Replace lens case at regular intervals as recom-
mended by the lens case manufacturer or your
eye care practitioner.
• Eye care practitioners may recommend a lubri-
cating/rewetting solution which can be used
to wet (lubricate) lenses while they are being
worn to make them more comfortable.
• Eye care practitioners may recommend a
weekly enzymatic cleaner which can be used to
effectively remove protein deposits from
Boston EQUALENS II Contact Lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
LENS CASE CLEANING AND MAINTENANCE
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry. Lens cases should be
replaced at regular intervals as recommended
by the lens case manufacturer or the eye care
practitioner.
CARE FOR A STICKING (NONMOVING) LENS
If the lens sticks (stops moving/cannot be
removed), the patient should be instructed to apply
one to three drops of a recommended lubricating
or rewetting solution directly to the eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL
EMERGENCY ROOM WITHOUT DELAY.
HOW SUPPLIED
Each lens is supplied (nonsterile) in a plastic lens
storage case. The case is labeled with the base
curve, diopter power, diameter, center thickness,
color, UV-absorber and lot number.
REPORTING OF ADVERSE REACTIONS
All serious adverse reactions observed in patients
wearing Boston EQUALENS II Contact Lenses or
adverse experiences with the lenses should be
reported to:
Consumer Affairs
Polymer Technology, a Bausch & Lomb company
1400 North Goodman Street
Rochester, NY 14609
1-800-333-4730
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:
Practitioner Marketing Representative
Polymer Technology, a Bausch & Lomb company

Rochester, NY 14609
1-800-225-1241
Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular
The lenses described above can have a center thick-
ness of 0.07 to 0.65 mm that will vary with lens
design, power and diameter.

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL

• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:

Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular
The lenses described above can have a center thick-
ness of 0.07 to 0.65 mm that will vary with lens
design, power and diameter.

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular
The lenses described above can have a center thick-
ness of 0.07 to 0.65 mm that will vary with lens
design, power and diameter.

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

information and specific instructions on the lens
care regimen recommended for the patient:
General Lens Care
(First Clean and Rinse, Then Disinfect Lenses)
Basic Instructions:
Always wash, rinse, and dry hands before handling
contact lenses.
• Always use fresh unexpired lens care solutions.
• Use the recommended system of lens care,
chemical (not heat) and carefully follow instruc-
tions on solution labeling. Different solutions
often cannot be used together, and not all solu-
tion are safe for use with all lenses. Do not alter-
nate or mix lens care systems unless
indicated on solution labeling or if advised
by the eye care practitioner.
• Do not use saliva or anything other than the rec-
ommended solutions for lubricating or rewetting
lenses. Do not put lenses in the mouth.
• Lenses should be cleaned, rinsed, and disin-
fected each time they are removed. Cleaning
and rinsing are necessary to remove mucus and
film from the lens surface. Disinfecting is neces-
sary to destroy harmful germs.

Replace lens case at regular intervals as recom-
mended by the lens case manufacturer or your
eye care practitioner.
• Eye care practitioners may recommend a lubri-
cating/rewetting solution which can be used
to wet (lubricate) lenses while they are being
worn to make them more comfortable.
• Eye care practitioners may recommend a
weekly enzymatic cleaner which can be used to
effectively remove protein deposits from
Boston EQUALENS II Contact Lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
LENS CASE CLEANING AND MAINTENANCE
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry. Lens cases should be
replaced at regular intervals as recommended
by the lens case manufacturer or the eye care
practitioner.
CARE FOR A STICKING (NONMOVING) LENS
If the lens sticks (stops moving/cannot be
removed), the patient should be instructed to apply
one to three drops of a recommended lubricating
or rewetting solution directly to the eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL
EMERGENCY ROOM WITHOUT DELAY.
HOW SUPPLIED
Each lens is supplied (nonsterile) in a plastic lens
storage case. The case is labeled with the base
curve, diopter power, diameter, center thickness,
color, UV-absorber and lot number.
REPORTING OF ADVERSE REACTIONS
All serious adverse reactions observed in patients
wearing Boston EQUALENS II Contact Lenses or
adverse experiences with the lenses should be
reported to:
Consumer Affairs
Polymer Technology, a Bausch & Lomb company
1400 North Goodman Street
Rochester, NY 14609
1-800-333-4730
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:
Practitioner Marketing Representative
Polymer Technology, a Bausch & Lomb company

Rochester, NY 14609
1-800-225-1241
Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction

favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

information and specific instructions on the lens
care regimen recommended for the patient:
General Lens Care
(First Clean and Rinse, Then Disinfect Lenses)
Basic Instructions:
Always wash, rinse, and dry hands before handling
contact lenses.
• Always use fresh unexpired lens care solutions.
• Use the recommended system of lens care,
chemical (not heat) and carefully follow instruc-
tions on solution labeling. Different solutions
often cannot be used together, and not all solu-
tion are safe for use with all lenses. Do not alter-
nate or mix lens care systems unless
indicated on solution labeling or if advised
by the eye care practitioner.
• Do not use saliva or anything other than the rec-
ommended solutions for lubricating or rewetting
lenses. Do not put lenses in the mouth.
• Lenses should be cleaned, rinsed, and disin-
fected each time they are removed. Cleaning
and rinsing are necessary to remove mucus and
film from the lens surface. Disinfecting is neces-
sary to destroy harmful germs.

Replace lens case at regular intervals as recom-
mended by the lens case manufacturer or your
eye care practitioner.
• Eye care practitioners may recommend a lubri-
cating/rewetting solution which can be used
to wet (lubricate) lenses while they are being
worn to make them more comfortable.
• Eye care practitioners may recommend a
weekly enzymatic cleaner which can be used to
effectively remove protein deposits from
Boston EQUALENS II Contact Lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
LENS CASE CLEANING AND MAINTENANCE
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry. Lens cases should be
replaced at regular intervals as recommended
by the lens case manufacturer or the eye care
practitioner.
CARE FOR A STICKING (NONMOVING) LENS
If the lens sticks (stops moving/cannot be
removed), the patient should be instructed to apply
one to three drops of a recommended lubricating
or rewetting solution directly to the eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL
EMERGENCY ROOM WITHOUT DELAY.
HOW SUPPLIED
Each lens is supplied (nonsterile) in a plastic lens
storage case. The case is labeled with the base
curve, diopter power, diameter, center thickness,
color, UV-absorber and lot number.
REPORTING OF ADVERSE REACTIONS
All serious adverse reactions observed in patients
wearing Boston EQUALENS II Contact Lenses or
adverse experiences with the lenses should be
reported to:
Consumer Affairs
Polymer Technology, a Bausch & Lomb company
1400 North Goodman Street
Rochester, NY 14609
1-800-333-4730
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:
Practitioner Marketing Representative
Polymer Technology, a Bausch & Lomb company

Rochester, NY 14609
1-800-225-1241
Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in

Replace lens case at regular intervals as recom-
mended by the lens case manufacturer or your
eye care practitioner.
• Eye care practitioners may recommend a lubri-
cating/rewetting solution which can be used
to wet (lubricate) lenses while they are being
worn to make them more comfortable.
• Eye care practitioners may recommend a
weekly enzymatic cleaner which can be used to
effectively remove protein deposits from
Boston EQUALENS II Contact Lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
LENS CASE CLEANING AND MAINTENANCE
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry. Lens cases should be
replaced at regular intervals as recommended
by the lens case manufacturer or the eye care
practitioner.
CARE FOR A STICKING (NONMOVING) LENS
If the lens sticks (stops moving/cannot be
removed), the patient should be instructed to apply
one to three drops of a recommended lubricating
or rewetting solution directly to the eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL
EMERGENCY ROOM WITHOUT DELAY.
HOW SUPPLIED
Each lens is supplied (nonsterile) in a plastic lens
storage case. The case is labeled with the base
curve, diopter power, diameter, center thickness,
color, UV-absorber and lot number.
REPORTING OF ADVERSE REACTIONS
All serious adverse reactions observed in patients
wearing Boston EQUALENS II Contact Lenses or
adverse experiences with the lenses should be
reported to:
Consumer Affairs
Polymer Technology, a Bausch & Lomb company
1400 North Goodman Street
Rochester, NY 14609
1-800-333-4730
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:
Practitioner Marketing Representative
Polymer Technology, a Bausch & Lomb company

Rochester, NY 14609
1-800-225-1241
Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular
The lenses described above can have a center thick-
ness of 0.07 to 0.65 mm that will vary with lens
design, power and diameter.

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

• Lenses should be cleaned, rinsed, and disin-
fected each time they are removed. Cleaning
and rinsing are necessary to remove mucus and
film from the lens surface. Disinfecting is neces-
sary to destroy harmful germs.

Replace lens case at regular intervals as recom-
mended by the lens case manufacturer or your
eye care practitioner.
• Eye care practitioners may recommend a lubri-
cating/rewetting solution which can be used
to wet (lubricate) lenses while they are being
worn to make them more comfortable.
• Eye care practitioners may recommend a
weekly enzymatic cleaner which can be used to
effectively remove protein deposits from
Boston EQUALENS II Contact Lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
LENS CASE CLEANING AND MAINTENANCE
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry. Lens cases should be
replaced at regular intervals as recommended
by the lens case manufacturer or the eye care
practitioner.
CARE FOR A STICKING (NONMOVING) LENS
If the lens sticks (stops moving/cannot be
removed), the patient should be instructed to apply
one to three drops of a recommended lubricating
or rewetting solution directly to the eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, the patient should
immediately consult the eye care practitioner.
EMERGENCIES
The patient should be informed that if chemicals
of any kind (household products, gardening solu-
tions, laboratory chemicals, etc.) are splashed into
the eyes, the patient should: FLUSH EYES IMMEDI-
ATELY WITH TAP WATER, THEN REMOVE LENSES
PROMPTLY, IF POSSIBLE, AND IMMEDIATELY CONTACT
THE EYE CARE PRACTITIONER OR VISIT A HOSPITAL
EMERGENCY ROOM WITHOUT DELAY.
HOW SUPPLIED
Each lens is supplied (nonsterile) in a plastic lens
storage case. The case is labeled with the base
curve, diopter power, diameter, center thickness,
color, UV-absorber and lot number.
REPORTING OF ADVERSE REACTIONS
All serious adverse reactions observed in patients
wearing Boston EQUALENS II Contact Lenses or
adverse experiences with the lenses should be
reported to:
Consumer Affairs
Polymer Technology, a Bausch & Lomb company
1400 North Goodman Street
Rochester, NY 14609
1-800-333-4730
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she
should be instructed to:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact the eye
care practitioner. If the lens has dirt, an eyelash, or
other foreign body on it, or the problem stops
and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the
lenses; then reinsert them. After reinsertion, if the
problem continues, immediately remove the
lenses and consult the eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. The patient
should be instructed to keep the lens off the eye
and seek immediate professional identification
of the problem and prompt treatment to avoid
serious eye damage.
FITTING
Conventional methods of fitting contact lenses
apply to Boston EQUALENS II (oprifocon A) Contact
Lenses. For a detailed description of the fitting
techniques, refer to the Boston EQUALENS II
Professional Fitting and Information Guide, copies
of which are available from:
Practitioner Marketing Representative

Rochester, NY 14609
1-800-225-1241
Professional Fitting Guides are also available
through your Authorized Boston Manufacturer.
WEARING SCHEDULE
The wearing and replacement schedules
should be determined by the eye care practi-
tioner. Patients tend to overwear the lenses ini-
tially. The eye care practitioner should emphasize
the importance of adhering to the initial maximum
wearing schedule. Regular checkups, as determined
by the eye care practitioner, are also extremely
important.
health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner’s office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
INDICATIONS (USES)
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practi-
tioner. The lens is indicated for extended wear for
the correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-dis-
eased eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correc-
tion of refractive ametropia (myopia, hyperopia,
astigmatism and presbyopia) in aphakic and not-
aphakic persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular
surface disorders may benefit from the physical
protection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion (dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which
is to be used to care for the Boston EQUALENS II
Contact Lenses.
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
Patients should be advised of the following warnings
pertaining to contact lens wear:
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It is
essential that patients follow their eye care prac-
titioner’s directions and all labeling instructions
for proper use of lenses and lens care products,
including the lens case. Eye problems, including
corneal ulcers, can develop rapidly and lead to
loss of vision.
DESCRIPTION
The Boston®EQUALENS®II Rigid Gas Permeable
Contact Lens material, oprifocon A, for daily wear
or extended wear is composed of methyl-methacrylate-
fluoroitaconate-siloxanyl copolymer with an ultravi-
olet absorber (Uvinul D-49). The lenses are available
in clear (untinted), blue, or green. The tinted lenses
contain the following color additives:
Color Color Additive
Blue D&C Green No. 6
Green D&C Green No. 6
D&C Yellow No. 18
The Boston EQUALENS Contact Lens is a hemi-
spherical shell of the following dimensions:
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient’s eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Daily wear lenses are not indicated for overnight
wear, and daily wear patients should be instructed
not to wear lenses while sleeping. Clinical studies
have shown that the risk of serious adverse reac-
tions is increased when these lenses are worn
overnight.
• If a patient experiences eye discomfort, excessive
tearing, vision changes, or redness of the eye, the
patient should be instructed to immediately
remove lenses and promptly contact his or her
eye care practitioner.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, suitability as an
extended wear patient should be discussed with
the eye care practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If the lenses are for
extended wear, the eye care practitioner may
prescribe more frequent visits.
PRECAUTIONS
• Patients may experience a reduction in visibility while
wearing this lens in conditions of low illumination for
the following colors and center thicknesses:
Color Center Thickness
Blue > 0.65 mm
Green > 0.55 mm
Special Precautions for Eye Care Practitioners:
• Due to the small number of patients enrolled in
clinical investigation of lenses, all refractive pow-
ers, design configurations, or lens parameters
available in the lens material are not evaluated
in significant numbers. Consequently, when
selecting an appropriate lens design and parame-
ters, the eye care practitioner should consider all
characteristics of the lens that can affect lens
performance and ocular health, including oxygen
permeability, wettability, central and peripheral
thickness, and optic zone diameter.
• The potential impact of these factors on the
patient's ocular health should be carefully
weighed against the patient's need for refractive
correction; therefore, the continuing ocular
The lenses described above can have a center thick-
ness of 0.07 to 0.65 mm that will vary with lens
design, power and diameter.

NOTE
Long term exposure to UV radiation is one of the
risk factors associated with cataracts. Exposure is
based on a number of factors such as environmen-
tal conditions (altitude, geography, cloud cover)
and personal factors (extent and nature of outdoor
actitivies). UV-absorbing contact lenses help pro-
vide protection against harmful UV radiation.
However, clinical studies have not been done to
demonstrate that wearing UV-absorbing contact
lenses reduces the risk of developing cataracts or
other eye disorders. Consult your eye care prati-
tioner for more information.
WARNING
UV-absorbing contact lenses are NOT substitutes
for protective UV-absorbing eyewear such as UV-
absorbing goggles or sunglasses. Persons should
continue to use their protective UV-absorbing
eyewear as directed.
ACTIONS
The Boston EQUALENS II Contact Lens when placed
on the human cornea, acts as a refracting medium
to focus light rays on the retina to improve visual
acuity. The toric lens provides a more even surface
over the highly uneven astigmatic cornea and thus
helps to focus light rays on the retina.

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a

2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies

gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.
WEARING AND APPOINTMENT SCHEDULES
DAILY WEAR (DURING WAKING HOURS)
Prescribed Wearing Schedule
DAY WEARING TIME (Hours)*
1 4 to 8 Hours
2 6 to 10 Hours
3 8 to 14 Hours
4 10 to 15 Hours
5 12 to All Waking Hours
6 and after All Waking Hours
*if the lenses continue to be well-tolerated.
Lenses should be removed daily for cleaning and
disinfecting for 4 hours (or overnight) before wearing.
EXTENDED WEAR (OVERNIGHT)
The prescribed wearing schedule for Boston
EQUALENS II Contact Lens for extended wear is to
initially adapt to daily wear during the first week of
wear as described above. During the second week,
you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.

quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-

will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of

wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
•If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
•Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.

you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper

There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.
WEARING AND APPOINTMENT SCHEDULES
DAILY WEAR (DURING WAKING HOURS)
Prescribed Wearing Schedule
DAY WEARING TIME (Hours)*
1 4 to 8 Hours
2 6 to 10 Hours
3 8 to 14 Hours
4 10 to 15 Hours
5 12 to All Waking Hours
6 and after All Waking Hours
*if the lenses continue to be well-tolerated.
Lenses should be removed daily for cleaning and
disinfecting for 4 hours (or overnight) before wearing.
EXTENDED WEAR (OVERNIGHT)
The prescribed wearing schedule for Boston
EQUALENS II Contact Lens for extended wear is to
initially adapt to daily wear during the first week of
wear as described above. During the second week,
you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®

OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes

ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.

EXTENDED WEAR (OVERNIGHT)
The prescribed wearing schedule for Boston
EQUALENS II Contact Lens for extended wear is to
initially adapt to daily wear during the first week of
wear as described above. During the second week,
you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing

• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.
WEARING AND APPOINTMENT SCHEDULES

Prescribed Wearing Schedule
DAY WEARING TIME (Hours)*
1 4 to 8 Hours
2 6 to 10 Hours
3 8 to 14 Hours
4 10 to 15 Hours
5 12 to All Waking Hours
6 and after All Waking Hours
*if the lenses continue to be well-tolerated.
Lenses should be removed daily for cleaning and
disinfecting for 4 hours (or overnight) before wearing.
EXTENDED WEAR (OVERNIGHT)
The prescribed wearing schedule for Boston
EQUALENS II Contact Lens for extended wear is to
initially adapt to daily wear during the first week of
wear as described above. During the second week,
you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight

• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers’ license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.
WEARING AND APPOINTMENT SCHEDULES
DAILY WEAR (DURING WAKING HOURS)
Prescribed Wearing Schedule
DAY WEARING TIME (Hours)*
1 4 to 8 Hours
2 6 to 10 Hours
3 8 to 14 Hours
4 10 to 15 Hours
5 12 to All Waking Hours
6 and after All Waking Hours
*if the lenses continue to be well-tolerated.
Lenses should be removed daily for cleaning and
disinfecting for 4 hours (or overnight) before wearing.
EXTENDED WEAR (OVERNIGHT)
The prescribed wearing schedule for Boston
EQUALENS II Contact Lens for extended wear is to
initially adapt to daily wear during the first week of
wear as described above. During the second week,
you should comfortably wear the lenses during all
waking hours. Then;
DAY WEARING TIME (Hours)*
15-21 24 hours a day
*if the lenses continue to be well-tolerated.
The maximum suggested wearing time for Boston
EQUALENS II Contact Lens/Lenses extended wear is
1 week (7 days). Lenses should be removed for
cleaning and disinfecting for 8-10 hours (overnight)
at the end of 1 week of extended wear, or more fre-
quently if recommended by your eye care practitioner.
2) Place the tip of the forefinger of one hand
on the middle of the upper lid margin and
the forefinger of the other hand on the
middle of the lower lid margin.
3) Press the lid margin inward and then
together. The lens should be wedged out of
your eye onto your hand or towel.
4) The lens may come out but remain on your
eyelid or hand or be decentered onto the
white part of your eye. If the latter occurs,
recenter the lens onto your cornea before
repeating the removal procedure.
BLINK METHOD
Seat yourself at a table covered with a clean
towel and lean over until you are looking down
at the surface.
1) Place your index finger at the outer junction
of your upper and lower lids, stretch the
skin outward and slightly upward. (Do not
allow your lid to slide over the lens.)
2) Blink briskly. The lens will be pinched by the
pressure of your eyelids and the lens will
pop out onto the clean surface of the
towel, or you may catch the lens in the palm
of your hand.
c. Remove the other lens by following the same
procedure.
d. Follow the required lens care procedures
described under the heading, CARING FOR
YOUR LENSES (CLEANING, RINSING, DISINFECT-
ING, STORAGE AND REWETTING/LUBRICATING).
Note: If these methods of removing your lenses
are difficult for you, your eye care practitioner
will provide you with an alternate method.
CARING FOR YOUR LENSES (CLEANING, RINSING,
DISINFECTING, STORAGE AND REWETTING/LUBRICATING)
1. Basic Instructions
For continued safe and comfortable wearing of
your lenses, it is important that you first clean
and rinse, then disinfect your lenses after each
removal, using the care regimen recommended
by your eye care practitioner. Cleaning and rins-
ing are necessary to remove mucus, secretions,
films, or deposits which may have accumulated
during wear. The ideal time to clean your lenses
is immediately after removing them. Disinfecting
is necessary to destroy harmful germs.
You should adhere to the recommended care
regimen. Failure to follow the regimen may result
in development of serious ocular complications
as discussed in the WARNINGS section above.
If you require only vision correction, but will not
or cannot adhere to a recommended care regi-
men for your lenses, or are unable to place and
remove lenses and do not have someone avail-
able to place and remove them for you, you
should not attempt to wear contact lenses.
When you first get your lenses, be sure you can
place the lenses on your eyes and remove them
while you are in your eye care practitioner’s
office. At that time you will be provided with a
recommended cleaning and disinfection regi-
men and instructions and warnings for lens care,
handling, cleaning, and disinfection. Your eye
care practitioner should instruct you about
appropriate and adequate procedures and prod-
ucts for your use, and provide you with a copy
of the Patient Instructions for the Boston
EQUALENS II Contact Lens.
• Dry eyes
If you notice any of the above:
• Immediately remove lenses.
• If the discomfort or problem stops, then look
closely at the lens. If the lens is in any way dam-
aged, do not put the lens back on the eye. Place
the lens in the storage case and contact your eye
care practitioner. If the lens has dirt, an eyelash,
or other foreign body on it, or the problem stops
and the lens appears undamaged, you should
thoroughly clean, rinse, and disinfect the lenses;
then reinsert them. After reinsertion, if the prob-
lem continues, immediately remove the lenses
and consult your eye care practitioner.
When any of the above problems occur, a serious
condition such as infection, corneal ulcer, neovas-
cularization, or iritis may be present. You should
keep the lens off the eye and seek immediate
professional identification of the problem and
prompt treatment to avoid serious eye damage.
PERSONAL CLEANLINESS FOR LENS HANDLING
1. Preparing the Lens for Wearing
It is essential that you learn and use good
hygienic methods in the care and handling of
your new lenses. Cleanliness is the first and most
important aspect of proper contact lens care. In
particular, your hands should be clean and free
of any foreign substances when you handle your
lenses. The procedures are:
• Always wash your hands thoroughly with a mild
soap, rinse completely, and dry with a lint-free
towel before touching your lenses.
• Avoid the use of soaps containing cold cream,
lotion, or oily cosmetics before handling your
lenses, since these substances may come into
contact with the lenses and interfere with suc-
cessful wearing.
• Handle the lenses with your fingertips, and be
careful to avoid contact with fingernails. It is
helpful to keep your fingernails short and
smooth.
Start off correctly by getting into the habit of
always using proper hygienic procedures so that
they become automatic.
2. Handling the Lenses
• Develop the habit of always working with the
same lens first to avoid mix-ups.
• Remove the lens from its storage case and
examine it to be sure that it is moist, clean,
clear, and free of any nicks or cracks.
3. Placing the Lens on the Eye
After thoroughly washing and rinsing your
hands, and after proper cleaning and condition-
ing of the lens, follow these steps to insert the
lens:
• Remove the lens from its storage compart-
ment.
• Rinse the lens with fresh conditioning solution,
if desired.
• Inspect the lens to be sure that it is clean, uni-
formly wet and free of debris.
• Rub several drops of conditioning solution over
the lens surfaces.
• Place the lens on the top of the index finger
of
your dominant hand. Place the middle finger
of the same hand close to the lower lash and
hold down the lower lid.
wear, and should not be worn while sleeping.
Clinical studies have shown that the risk of serious
adverse reactions is increased when these lenses
are worn overnight.
• The risk of ulcerative keratitis has been shown to
be greater among users of extended wear lenses
than among users of daily wear lenses. The risk
among extended wear lens users increases with
the number of consecutive days that lenses are
worn between removals, beginning with the first
overnight use. This risk can be reduced by care-
fully following directions for routine lens care,
including cleaning of the lens case. Additionally,
smoking increases the risk of ulcerative keratitis
for contact lens users.
• Clinical studies indicate that the majority of
patients who wish to wear Boston EQUALENS II
Contact Lenses for extended wear do so with
favorable results. However, your suitability as an
extended wear patient should be discussed with
your contact lens practitioner.
• All contact lens wearers must see their eye care
practitioner as directed. If your lenses are for
extended wear, your eye care practitioner may
prescribe more frequent visits.
• Studies have shown that contact lens wearers
who are smokers have a higher incidence of
adverse reactions than nonsmokers.
PRECAUTIONS
You should carefully adhere to the following care
regimen and safety precautions:
• Before leaving the eye care practitioner’s office,
you should be able to promptly remove lenses or
should have someone else available who can
remove the lenses for you.
• You should remove your lens immediately if your
eye becomes red or irritated.
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution and
lenses. Keep them away from extreme heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package insert
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Sterile unpreserved solutions, when used,
should be discarded after the time specified in
the labeling directions.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blot-
ting with a soft lint-free tissue prior to being

INTRODUCTION
Boston®EQUALENS®II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
• Use the forefinger or middle finger of your
other hand to lift the upper lid and then place
the lens on the eye. It is not necessary to press
the lens against the eye.
• Gently release the lids and blink. The lens will
center automatically. Always verify its proper
position by checking your vision immediately
after insertion.
• Use the same technique or reverse the hand
when inserting the other lens.
There are other methods of lens placement. If
the above method is difficult for you, your eye
care practitioner will provide you with an alter-
nate method.
Note: If after placement of the lens, your vision
is blurred, check for the following:
• The lens is not centered on the eye (see
“Centering the Lens,” next in this booklet).
• If the lens is centered, remove the lens (see
“Removing the Lens” section) and check for
the following:
a. Cosmetics or oils on the lens. Clean, rinse,
disinfect, and place on the eye again.
b. The lens is on the wrong eye.
If you find that your vision is still blurred after
checking the above possibilities, remove both
lenses and consult your eye care practitioner.
4. Centering the Lens
Very rarely, a lens that is on the cornea will be
displaced onto the white part of the eye during
lens wear. This can also occur during placement
and removal of the lenses if the correct tech-
niques are not performed properly. To center a
lens follow one of the procedures below.
• Close your eyelids and gently massage the lens
into place through the closed lids.
OR
• Gently push the off-centered lens onto the
cornea while the eye is open using finger pres-
sure on the upper or lower lid next to the edge
of the lens.
5. Removing the Lens
Before removing your lenses, it is recommended
that you have the following items available:
1) A lens storage case.
2) Two Bottle Care System
Boston ADVANCE®Cleaner or
Boston® Cleaner. AND
Boston ADVANCE®Comfort Formula
Conditioning Solution or Boston®
Conditioning Solution.
OR
One Bottle Care System
Boston SIMPLUS™ Multi-Action Solution
(Removes Protein, Cleans, Disinfects,
Conditions & Cushions) or
Boston SIMPLICITY® Multi-Action Solution
(Clean, Condition, Disinfect, Rinse & Cushion)
3) A clean towel.
Always remove the same lens first.
a. Wash, rinse, and dry your hands thoroughly.
b. There are two suggested methods of lens
removal:
TWO-FINGER METHOD
1) Place a towel under your eye to catch the
lens.
placed in a clean, dry lens storage case. Ideally,
these lenses should be rehydrated overnight
prior to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, immediately
consult your eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before
putting on makeup. Water-based cosmetics are
less likely to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing in-
structions that follow for the Boston EQUALENS II
Contact Lens and those prescribed by the eye care
practitioner.
• Never wear lenses beyond the period recom-
mended by your eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that you
not wear contact lenses.
• As with any contact lens, follow-up visits are nec-
essary to assure the continuing health of your
eyes. Follow your eye care practitioner’s instruc-
tion as to a recommended follow-up schedule.
ADVERSE EFFECTS
The following problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
• Sensitivity to light (photophobia)
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner’s
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight
