Contraindications
The use of this device is contraindicated in patients who have already received pro-
longed or intense light exposure, especially if the patients are infants, aphakes, or per-
sons with diseased eyes. Excessive exposure to light may result in patient injury. See
warnings for additional information.
General Warnings
A warning statement in this manual identifies a condition or practice
which, if not corrected or discontinued immediately, could lead to patient
injury, illness, or death.
CAUTION: Because prolonged intense light exposure can damage the retina, the use
of the device for ocular examination should not be unnecessarily prolonged, and the
brightness setting should not exceed what is needed to provide clear visualization of
the target structures.
The retinal exposure dose for a photochemical hazard is a product of the radiance and
the exposure time. If the value of radiance were reduced in half, twice the time would
be needed to reach the maximum exposure limit.
While no acute optical radiation hazards have been identified for direct or indirect oph-
thalmoscopes, it is recommended that the intensity of light directed into the patient's
eye be limited to the minimum level which is necessary for diagnosis. Infants,
aphakes and persons with diseased eyes will be at greater risk. The risk may also be
increased if the person being examined has had any exposure with the same instru-
ment or any other ophthalmic instrument using a visible light source during the previ-
ous 24 hours. This will apply particularly if the eye has been exposed to retinal
photography.
WARNING: The carrying cases provided with these devices are intended for long
term storage or transport between facilities or when shipping devices to and from
ADC’s facility for repair or servicing. Carry cases (including internal liners) can NOT
