Operation of the instrument
WARNING - RISK OF OPTICAL RADIATION
This is a group 2 device according to ISO 15004-2:2007.
The light emitted by this device may be harmful. The risk of eye damage
increases with the length of exposure to rays. Exposure at maximum
intensity for more than 4.9 min will exceed the hazard reference value.
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. This device should be used with
filters that eliminate UV radiation (< 400 nm) and, whenever possible, filters
that eliminate short-wavelength blue light (< 420 nm).
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 slit lamps,
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 instrument or any other ophthalmic instrument using a visible
light source during the previous 24 hours. This will apply particularly if the
eye has been exposed to retinal photography.
WARNING - RISK OF OPTICAL RADIATION
When operating the device, avoid looking directly into the light emitting
prism.
Never look into the sun through the binocular tube and eyepieces.
Take particular care when examining infants and aphakic patients.
It is not allowed to use a 90 D additional lens.
CAUTION - GENERAL HAZARDS
The patient should not touch the instrument with his/her hands. In
particular, the instrument should not be used as a support or an aid for
standing up.
