1. INTRODUCTION
The stenfilcon A Soft (hydrophilic) Contact Lenses are soft lenses. They are made from a "water-loving"
(hydrophilic) material that has the ability to absorb water, making the lens soft and flexible.
The stenfilcon A soft (hydrophilic) lenses are indicated for single use daily disposable wear. As prescribed
for single use daily disposable wear, once removed, they are to be discarded. They are not intended to be
cleaned and disinfected. You should always have replacement lenses or glasses available.
The information and instructions contained in this booklet apply only to stenfilcon A, stenfilcon A Toric,
stenfilcon A Multifocal, and stenfilcon A Multifocal Toric soft (hydrophilic) contact lens, referred to as your
contact lenses. For your eye health, it is important to wear your lenses as prescribed by your Eye Care
Practitioner. It is also important to keep your Eye Care Practitioner fully aware of your medical history. Your
Eye Care Practitioner will tailor a total program of care based on your specific needs. He or she will review
with you all instructions for lens handling, including how to safely and easily open the package. You will
receive instruction on how to properly insert and remove lenses. This booklet will reinforce those
instructions. Discard and replace your contact lenses with a new sterile pair, as prescribed by your Eye
Care Practitioner.
Please refer to the Section 13, GLOSSARY OF TECHNICAL TERMS, for definitions of medical/technical
terms used in this booklet.
1.1. Benefits1
Contact lenses provide vision correction.
If you lead an active lifestyle, contacts can provide:
•close to natural vision.
•excellent peripheral vision for sports and driving.
•advantages for athletes and those with an active lifestyle.
If you work or play in an environment in which glasses are not an option, contact lenses are an alternative.
If you prefer the way you look without glasses, contact lenses can provide ease, and convenience.
1.2. Risks2
Wearing contact lenses puts you at risk of several serious conditions including eye infections and corneal
ulcers. These conditions can develop very quickly and can be very serious. In rare cases, these conditions
can cause blindness. Other risks of contact lenses include pink eye (conjunctivitis), corneal abrasions and
eye irritation. For further detail, see Section 4, WARNINGS, and Section 6, ADVERSE REACTIONS.

3. CONTRAINDICATIONS (REASONS NOT TO USE)
Do not use your contact lenses when any of the following conditions exist:
•Acute and 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 dry eye.
•Reduced corneal sensitivity (corneal hypoesthaesia).
•Any systemic disease that may affect the eye or be exaggerated by wearing contact lenses. For
example, Sjogren's syndrome, rheumatoid arthritis, lupus and collagen vascular diseases affect your
ability to wear contact lenses.
•Allergic reactions of ocular surfaces or surrounding tissues (adnexa) that may be induced or
exaggerated by wearing contact lenses or use of contact lens solutions.
•An allergic reaction can occur to any ingredient in contact lens solutions. Example: some people are
allergic to the trace amounts of mercury or thimerosal included as active ingredient in some contact
lens solutions.
•Any active corneal infection (bacterial, fungal, or viral).
•If eyes become red or irritated.
•If you are unable to follow lens care regimen or unable to obtain assistance to do so.
4. WARNINGS
What You Should Know About Contact Lens Wear:
UV-absorbing contact lenses are NOT substitutes for protective UV-absorbing eyewear, such as
UV-absorbing goggles or sunglasses because they do not completely cover the eye and the
surrounding area. You should continue to use UV-absorbing eyewear as directed.
Long term exposure to the UV raditation is one of the risk factors associated with cataracts.
Exposure is based on a number of factors such as environmental conditions (altitude, geography,
cloud cover) and personal factors (extent and nature of the outdoor activities). UV-absorbing
contact lenses help provide 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 Practitioner for more
information.
PROBLEMS WITH CONTACT LENSES AND LENS CARE PRODUCTS COULD RESULT IN SERIOUS
INJURY TO THE EYE. It is essential that patients follow Eye Care Practitioner’s directions and all labeling
instructions for proper use of lenses. Eye problems, including corneal ulcers, can develop rapidly and lead
to loss of vision. Daily wear lenses are not indicated for overnight wear, and patients should be instructed
not to wear lenses while sleeping. Clinical studies have shown that the risk of serious adverse reactions is

Part Number: PIB01054 Page 5 of 18
Revision: A Revision Date: June 2020
increased when these lenses are worn overnight. Studies have shown that contact lens wearers who are
smokers have a higher incidence of adverse reactions than nonsmokers. 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.
The results of a study3indicate the following:
a. The overall annual incidence of infected corneal ulcer (ulcerative keratitis) in daily wear contact
lens users is estimated to be about 4.1 per 10,000 persons and about 20.9 per 10,000 persons in
extended wear contact lens users.
b. The risk of infected corneal ulcer (ulcerative keratitis) is 4 to 5 times greater for extended wear
contact lens users than for daily wear users. When daily wear users who wear their lenses overnight
and extended wear users who wear their lenses on a daily basis are excluded from the comparison,
the risk among extended wear users are 10 to 15 times greater than among daily wear users.
c. When daily users wear their lenses overnight (outside the approvedindication), the risk ofulcerative
keratitis is 9 times greater than among those who do not wear them overnight.
d. The overall risk of infected corneal ulcer (ulcerative keratitis) may be reduced by carefully following
directions for lens care, including cleaning the lens case.
e. The risk of infected corneal ulcer (ulcerative keratitis) among contact lens users who smoke is
estimated to be 3 to 8 times greater than among non-smokers.
f. If you experience eye discomfort, excessive tearing, vision changes, redness of the eye or other
problems, you should be instructed to immediately remove your lenses and promptly contact your
Eye Care Practitioner. It is recommended that you see your Eye Care Practitioner routinely as
directed.
5. PRECAUTIONS
Handling Precautions:
•Do not use if the sterile blister package is opened or damaged.
•Always wash and rinse hands before handling lenses. Do not get cosmetics, lotions, soaps, creams,
deodorant, 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.
•Lens damage may occur if you handle your lens with dirty hands.
•Carefully follow the handling, insertion, removal, cleaning, and wearing instructions prescribed by your
Eye Care Practitioner.
•Always handle lenses gently and avoid dropping them.
•Never use tweezers or other tools to remove lenses from the lens container. Pour the lens and
packaging solution into your hand.
•Do not touch the lens with fingernails.
Lens Wearing Precautions:
•Never wear your lenses beyond the period recommended by your Eye Care Practitioner.
•If aerosol products such as hairspray are used while wearing lenses, be careful and keep eyes closed
until the spray has settled.
•Avoid all harmful or irritating vapors and fumes while wearing lenses.
•Ask your Eye Care Practitioner about wearing the lenses during sporting activities.

Part Number: PIB01054 Page 6 of 18
Revision: A Revision Date: June 2020
•Always discard lenses following the recommended replacement schedule prescribed by your Eye Care
Practitioner.
Who Should Know That You Are Wearing Contact Lenses:
•Inform your doctor (health care practitioner) that you wear contact lenses.
•Always inform your employer that you wear contact lenses. Some jobs may require use of eye
protection equipment or may restrict contact lens wear.
•Always contact your Eye Care Practitioner before using any medicine in your eyes.
Other Topics to Discuss with Your Eye Care Practitioner:
•Follow-up visits are necessary to assure the continued health of your eyes. You should be instructed
to a recommended follow-up schedule.
6. ADVERSE REACTIONS (PROBLEMS AND WHAT TO DO)
Be aware that the following problems may occur when wearing contact lenses:
•Your eyes may burn, sting and/or itch or you may experience other eye pain.
•Comfort may be less than when the lens was first placed on the eye.
•There may be a feeling that something is in the eye such as a foreign body or a scratched area.
•There may be excessive watering (tearing), unusual eye secretions or redness of your eye.
•Reduced sharpness of vision (poor visual acuity).
•Blurred vision, rainbows, or halos around objects, sensitivity to light (photophobia) or dry eyes may also
occur if your lenses are worn continuously or for too long a time.
If you notice any of the above, you should:
•Immediately remove the lenses.
•If the discomfort or the problem stops, then look closely at the lens.
oIf the lens is in some way damaged, do not put the lens back on the eye. You should discard the
lens and insert a fresh lens on your eye.
If the problem continues, you should immediately remove the lenses and consult your Eye Care
Practitioner. You should keep the lens off the eye and seek immediate professional identification of the
problem and prompt treatment to avoid serious eye damage. Your Eye Care Practitioner will examine your
eyes, to be certain that a serious condition such as infection, corneal ulcer, neovascularization, or swelling
of the colored part of the eye (iritis) is not present.

7. INSTRUCTIONS FOR LENS HANDLING
7.1. 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. These substances may contact the lenses and interfere with successful wearing.
•Handle your lenses with your fingertips. Be careful to avoid touching the lens with fingernails.
It is helpful to keep your fingernails short and smooth.
Start correctly; always use proper hygienic procedures.
7.2. Lens Package
The individual package is designed specifically to maintain sterility. The lens packages are
individual.
To open an individual lens package, follow these simple steps:
•Shake the lens package and check to see that the lens is floating in the solution.
•Peel back the foil closure to reveal the lens. Stabilizing the lens package on the tabletop, will
minimize the possibility of a sudden splash.
Occasionally on opening, a lens may adhere to the inside surface of the foilor to the plastic package
itself. This will not affect the sterility of the lens. It is still perfectly safe to use. Carefully remove and
inspect the lens following the handling instructions.

Part Number: PIB01054 Page 8 of 18
Revision: A Revision Date: June 2020
7.3. Handling the Lenses
•Develop the habit of always working with the right lens first to avoid mix-ups.
•Remove the right lens from its storage case and examine it to be sure that it is moist, clean,
clear, and free of any nicks or tears. If the lens appears damaged, do not use it. Use a new
lens.
Verify that the lens is not turned inside out by placing it on your forefinger and checking its profile.
The lens should assume a natural, curved, bowl-like shape (Fig. A). If the lens edges tend to point
outward, the lens is inside out (Fig. B).
Another method is to gently squeeze the lens between the thumb and forefinger. The edges should
turn inward (Fig A). If the lens is inside out, the edges will turn slightly outward (Fig. B).
Fig. A
Fig. B
7.4. Placing the Lens on the Eye
Start with your right eye.
Once you have opened the lens package, removed and examined the lens, follow these steps to
apply the lens to your eye:
a. Place the lens on the tip of your forefinger. BE SURE THE LENS IS CORRECTLY
ORIENTED (see Section 7.3 "Handling the Lenses").
b. Place the middle finger of the same hand close to your lower eyelashes and pull down the
lower lid (Fig. C).
c. Use the forefinger or middle finger of the other hand to lift the upper lid.
d. Place the lens on the eye (Fig. D).
e. Gently release the lids and blink. The lens will center automatically.
f. Use the same technique when inserting the lens for your left eye.

Part Number: PIB01054 Page 9 of 18
Revision: A Revision Date: June 2020
There are other methods of lens placement. If the above method is difficult for you, your Eye Care
Practitioner will provide you with an alternate method.
Fig. C
Fig. D
Note: If after placement of the lens, your vision is blurred, check for the following:
•The lens not centered on the eye (see Section 7.5 "Centering the Lens").
•If the lens is centered, remove the lens (see Section 7.6 "Removing the Lens") and
check for the following:
a. Cosmetics or oils on the lens. Clean the lens.
b. The lens is on the wrong eye.
c. The lens is inside out (it would also not be as comfortable as normal).
If you find your vision remains blurred after checking the above possibilities, remove both lenses
and consult your Eye Care Practitioner.
After you have successfully inserted your lenses, you should ask yourself:
•How do the lenses feel in my eye?
•How do my eyes look?
•Do I see well?
If your examination shows any problems IMMEDIATELY REMOVE YOUR LENSES AND CONTACT
YOUR EYE CARE PRACTITIONER.

7.5. Centering the Lens
A lens on the cornea (center of your eye) will rarely be displaced onto the white part of the eye
during wear. This can occur if insertion or removal procedures are not properly performed. To
center a lens, follow either of these procedures:
a. Close your eyelids and gently massage the lens into place through the closed lids.
OR
b. Gently manipulate the off-centered lens onto the cornea while the eye is open, using finger
pressure on the edge of the upper lid or lower lid.
7.6. Removing the Lens
CAUTION: Always be sure the lens is on the cornea before attempting to remove it. Determine
this by covering the other eye. If vision is blurred, the lens is either on the white part of the eye or
it is not on the eye at all. To locate the lens, inspect the upper area of the eye by looking down into
a mirror while pulling the upper lid up. Then, inspect the lower area by pulling the lower lid down.
a. Wash your hands thoroughly with a mild soap, rinse completely, and dry with a lint-free towel
before touching your lenses.
b. Remove the right lens first. There are two recommended methods of lens removal: the Pinch
Method and the Forefinger and Thumb Method. You should follow the method that your Eye
Care Practitioner recommended.
Pinch Method for removing lens:
Step 1. Look up; slide the lens to the lower part of the eye using the forefinger. (Fig. E)
Step 2. Gently pinch the lens between the thumb and forefinger. (Fig. F)
Step 3. Remove the lens.
Fig. E
Fig. F
Forefinger and Thumb Method for removing lens:
Step 1. Place your hand or a towel under your eye to catch the lens.
Step 2. Place your forefinger on the center of the upper lid and your thumb on the center
of the lower lid.
Step 3. Press in and force a blink. The lens should fall onto your hand.
Once you remove the lens, simply follow the lens care directions recommended
by the Eye Care Practitioner.
Note: The lens may come out but remain on the eyelid, finger or thumb.

Part Number: PIB01054 Page 11 of 18
Revision: A Revision Date: June 2020
c. Remove the other lens by following the same procedure.
d. When prescribed for single use daily disposable wear, patients are instructed to dispose of the
lens at each removal.
Note: If these methods of removing your lenses are difficult for you, your Eye Care Practitioner
will show you with an alternate method.
8. CARING FOR YOUR LENSES
8.1. Basic Instructions
The stenfilcon A Soft (Hydrophilic) Contact Lenses are indicated for daily wear single use only.The
lenses are to be discarded upon removal; therefore, no cleaning or disinfection is required.
You should adhere to recommended care regimen. Failure to follow the regimen may result in
development of serious ocular complications, as discussed in Section 4, WARNINGS.
If you require only vision correction but will not or cannot adhere to a recommended care regimen
for your lenses, or are unable to place and remove lenses, or have someone available to place and
remove them, you should not attempt to get and wear contact lenses.
As prescribed for single use daily disposable wear, once removed, they are to be discarded. They
are not intended to be cleaned and disinfected. You should always have replacement lenses or
glasses available.
For safe contact lens wear, you should know and always practice your lens care routine:
•Always wash your hands thoroughly with a mild soap. Rinse completely. 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. These substances may contact the lenses and interfere with successful wearing.
•Handle your lenses with your fingertips. Be careful to avoid contact with fingernails. It is helpful
to keep your fingernails short and smooth.
•Do not use saliva or anything other than the recommendedsolutionsfor lubricating or rewetting
your lenses. Do not put lenses in your mouth.
•Lenses should be thrown away after the recommended wearing period prescribed by your Eye
Care Practitioner.
•Never rinse your lenses in water from the tap. There are two reasons for this:
a. Tap water contains many impurities that can contaminate or damage your lenses and may
lead to eye infection or injury.
b. You might lose your lens down the drain.
•Since the lens material contains silicone, the ability of the lens to remain soft and flexible
(wettability) may differ when different lens care products are used. Your Eye Care Practitioner
should recommend a care system that is appropriate for you. Each lens care product contains
specific directions for use and importantsafety information,which you should readand carefully
follow.

Part Number: PIB01054 Page 12 of 18
Revision: A Revision Date: June 2020
Lubricating/Rewetting
Your Eye Care Practitioner may recommend a lubrication or rewetting solution for your use. These
solutions can be used to wet (lubricate) your lenses while you are wearing them tomake lens wear more
comfortable.
8.2. Care for a Sticking (Non-moving) Lens
If a lens sticks (stops moving) on your eye, apply a few drops of the recommended lubricating
solution. You should wait until the lens begins to move freely on the eye before removing it. If non-
movement of the lens continues, you should IMMEDIATELY consult your Eye Care Practitioner.
8.3. Care for a Dehydrated Lens
If a soft, hydrophilic contact lens is exposed to air while off the eye, it may become dry and brittle.
If this happens, dispose of the lens and use a fresh new one.
8.4. Emergencies
If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are
splashed into your eyes: FLUSH EYES IMMEDIATELY WITH WATER AND IMMEDIATELY
CONTACT YOUR EYE CARE PRACTITIONER OR VISIT A HOSPITAL EMERGENCY ROOM
WITHOUT DELAY.

Part Number: PIB01054 Page 13 of 18
Revision: A Revision Date: June 2020
9. INSTRUCTIONS FOR THE PRESBYOPIC PATIENT (MULTIFOCAL OR
MONOVISION WEARER)
Two common methods of using contact lenses for presbyopic vision correction include
multifocal and monovision.
Monovision: a treatment technique often prescribed for people age 40 and overwho have presbyopia.
Presbyopia occurs as part of the natural aging process. The eye’s crystalline lens loses its ability to
bring close objects into clear focus. Monovision means wearing a contact lens for near vision on one
eye and, if needed, a lens for distance vision on the other eye. (Ref: American Optometric Association)
Multifocal contact lenses have separate powers for distance and near vision in each lens. This allows
the wearer to use both eyes for seeing at all distances.
•The decision to be fit with a monovision correction or multifocal contact lenses is made by careful
consideration and discussion of your needs with your Eye Care Practitioner.
•As with any type of vision correction, you should be aware that there are advantages and tradeoffs with
multifocal or monovision contact lens correction. The benefit of clear near vision in straight ahead and
upward gaze that is available may be accompanied by a reduction in your visual acuity and depth
perception for distance and near tasks. Some patients experience difficulty adapting to monovision.
Symptoms, such as mild blurred vision, dizziness, headaches and a feeling of slight imbalance, may
last for a brief minute or for several weeks as adaptation takes place. The longer these symptoms
persist, the poorer 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 might be better to be a
passenger rather than a driver of an automobile during the first few days of monovision lens wear. It is
recommended that you only drive with monovision correction if you pass your state drivers license
requirements with monovision correction.
•Some patients will never be fully comfortable functioning under low levels of lighting, such as driving at
night.If this happens, you may want to discusswith your EyeCare Practitionerhaving additionalcontact
lenses prescribed so that both eyes are corrected optimally for distance when sharp distance binocular
vision is required.
•If you require very sharp near vision during prolonged close work, you may need to wear spectacles
over your lenses or have additional contact lenses prescribed specifically for this task so that both eyes
are corrected for near when sharp near binocular vision is required.
•Some monovision patients require supplemental glasses 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 presbyopic
contact lens therapy. During the adaptation period you should make careful note of any specific
situation where you feel unable to function effectively and safely, and discuss any concerns that you
may have during and after the adaptation period.

Remedy for a Non Centered Lens
A lens, which is on the cornea (center of your eye), will very rarely be displaced onto the white part
of the eye during wear. This, however, can occur if insertion and removal procedures are not
performed properly. To center a lens, follow either of these procedures:
a. Close your eyelids and gently massage the lens into place through the closed lids.
OR
b. Gently manipulate the off-centered lens onto the cornea while the eye is opened, using finger
pressure on the edge of the upper lid or lower lid.
Remedy for a Sticking Lens
If a lens sticks (stops moving) on your eye, apply a few drops of the recommended lubricating
solution. You should wait until the lens begins to move freely on the eye before removing it. If non-
movement of the lens continues, you should IMMEDIATELY consult your Eye Care Practitioner.
Dried Lens in Case
If exposed to air while off the eye, a soft hydrophilic contact lens may become dry and brittle. If this
happens, dispose of the lens and use a fresh new one.
