This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
Ocular Protection
WARNING: LASER HAZARD
Never look directly into the laser aperture or scattered laser light from reflective surfaces
when the treatment beam is activated. Severe eye damage could occur.
Never look into the path of a laser beam. Laser safety eyewear only offers protection against
stray or diffuse laser beam energy for a maximum exposure of 10 seconds.
Never substitute glass prescription eyewear for the appropriate laser safety eyewear, as
severe eye damage could occur. The glass in prescription eyewear can concentrate the laser
light onto the retina. A high power density beam can also shatter glass prescription eyewear,
resulting in possible severe eye damage.
Do not use eyewear that is broken or damaged.
The
(laser emission) indicator is displayed on the Treatment screen to warn the user that
the system is capable of emitting laser energy. Appropriate precautions, such as wearing
appropriate eyewear in the room, should be taken.
As a precaution against accidental exposure to the output beam or its reflection, anyone
checking or adjusting calibration should wear appropriate laser safety eyewear.
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 slit lamps, it is
recommended that the intensity of light directed into the patient’s eye be limited to the
minimum level that is necessary for diagnosis. Infants, aphakes and persons with diseased
eyes will be at greater risk. The risk may also increase 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. The red diode laser aiming beam has an average
