Below are some restrictions for this instrument for specific patients:

•
Patients who recently underwent photodynamic therapy (PDT).
•
Patients taking medication that causes photosensitivity.
•
Patients with a history of migraines.
•
Patients with a history of photosensitive epilepsy.
•
Patients with any kind of disease which could be induced by flash or
strong light.
Camera Handling– The camera should be protected from excessive vibration,
force, or pressure. Certain conditions such as dropping or hitting the camera
against a hard surface, or exerting excessive force on the lens or the monitor
may damage the lens, the monitor, or the control unit and also cause the camera
to malfunction or prevent recording. Also, as the camera is not dust resistant,
splash resistant, or waterproof, the camera should not be used in places with
excessive dust or sand, or where water can come into contact with the camera.
Sudden changes in temperature or humidity should be avoided as condensation
may result from such conditions, which may soil the lens or the monitor, causing
mold or damage to the camera. If condensation does occur, the camera should
be turned off for about 2 hours before using it. Once the camera adjusts to the
surrounding temperature, the fogging will clear naturally. The camera should
be avoided in extremely dusty conditions or sandy places, or rain or moisture,
which present the risk of sand, water, or foreign material entering the camera
through the lens or gaps around buttons. Such conditions may cause irreparable
damage to the camera.
It is recommended that the intensity of light directed into the patient's eye be
limited to the minimum level necessary for diagnosis. Infants and persons
with diseased eyes are at greater risk. The risk may also be increased if the
person being examined has had any exposure to the same instrument or any
other ophthalmic instrument that uses a visible light source within the previous
24 hours. This will apply particularly if the eye has been exposed to retinal
photography. The intended use of this device is for routine ophthalmic exams
of typically less than 60 seconds per eye. While any medical procedure has its
benefit versus risk factor, more complicated exams should not exceed 3 minutes
of exam time within 24 hours. Significant use of this device beyond its intended
use is not recommended as it may cause harm to the eyes.
