Warnings and Cautions
Authorized representative in the European Community
Global Trade Item Number
WARNING: The light emitted from the ophthalmoscope is
potentially hazardous. The longer the duration of exposure, the
greater the risk of ocular damage. Exposure to light from this
instrument, when operated at maximum intensity, will exceed
the safety guideline after 13 minutes when lit with a LED lamp
(blue base). Exposure times are cumulative for a 24-hour
period.
WARNING: When using Halogen illumination, no acute optical
radiation hazards are identified. However, Welch Allyn
recommends limiting the intensity of the light directed into the
patient’s eye to the minimum level that is necessary for
diagnosis. Infants, aphakes, and persons with diseased eyes
are at a greater risk. The risk is also increased if the examined
person has had any exposure with the same instrument or any
other ophthalmic instrument using a visible light source within
the previous 24 hours. This will apply particularly if the eye has
had exposure to retinal photography. The intended use of this
device is for routine ophthalmic exams on the order of typically
less than 60 seconds per eye. Although there is a benefit
versus risk factor in any medical procedure, these more
complicated exams should not exceed a three minute exam
time in 24 hours. Significant use of this device beyond its
intended use is not recommended; it may cause harm to the
eyes.

WARNING: To minimize lamp housing temperatures, on-
time should not exceed 2 minutes with off-time not less than
10 minutes.
WARNING: Use only PanOptic Patient Eyecups with this
product.
WARNING: Rx only (for professional use).
WARNING: Lamps may be hot. Lamp should be allowed to
cool before removal.
WARNING: Equipment not suitable for use in the presence
of a flammable anesthetic.
Caution: Halogen lamps are pressurized to provide
maximum efficiency and illumination. Mistreatment may
cause shattering. Protect lamp surface against abrasion and
scratches. Verify power is off when replacing lamp. Dispose
of lamp with care.
Note A graph of the relative spectral output of the instrument is
available upon request.

The PanOptic™Ophthalmoscope
Transparency of the cornea, lens and vitreous humor permits the
practitioner to directly view arteries, veins, and the optic nerve of the
retina.
Direct observation of the structures of the fundus through a PanOptic
Ophthalmoscope may show disease of the eye itself or may reveal
abnormalities indicative of disease elsewhere in the body. Among the
most important of these are vascular changes due to diabetes or
hypertension and swelling of the optic nerve head due to papilledema
or optic neuritis. In this sense, the eye serves as a window through
which many valuable clinical evaluations may be made.
When a preliminary diagnosis of an imminently dangerous eye
condition, such as acute (angle-closure) glaucoma or retinal
detachment, is made by the examiner, prompt referral to an eye
specialist may prevent irreversible damage. Or, when distressing but
less urgent conditions, such as visual impairment due to cataract or
vitreous floaters, are recognized, the patient can be reassured and
referred.

Set-up Instructions
Attaching the Pan Optic
Ophthalmoscope head to a Welch
Allyn Power Source
Align cutouts in the PanOptic
Ophthalmoscope base with lugs on
power source. (The PanOptic
Ophthalmoscope fits all 3.5v Welch
Allyn power sources.) Push in slightly
and turn 90 degrees.
Attaching the Patient Eyecup to PanOptic
Insert eyecup into the patient’s side of
the instrument. Push and twist in one
motion until you feel the two “lock”
together.
See “Accessory and Replacement
Parts List” on page 19 to reorder new
PanOptic Patient Eyecups.
WARNING: Use only PanOptic Patient Eyecups with this
product.

Attaching Corneal Viewing Lens to PanOptic (Model 11820 only)
Insert Corneal Viewing Lens into patient’s side of the instrument. Push
and twist in one motion until you feel the two “lock” together as
shown on page 5, except replacing Patient Eyecup with the Corneal
Viewing Lens. Verify that the line on the lens housing is aligned with
the top seam of the PanOptic instrument.
