2.5 Risk due to optical radiation
This is a group 2 device according to ISO 15004-2:2007.
The light emitted by this device is potentially hazardous. The longer
the duration of exposure, the greater the risk of ocular damage.
Exposure to light from this device when operated at maximum
intensity will exceed the safety guideline for the aphakic eye after
48 s.
Because prolonged intense light exposure can damage the retina,
the use of the device for ocular examination should not be unnec-
essarily prolonged, and the brightness setting should not exceed
what is needed to provide clear visualization of the target struc-
tures.
Some groups of people will be at greater risk due to anatomical
conditions (e.g. infants, aphakes and persons with diseased eyes).
The risk may also be increased if the patient being examined has
recently had any exposure to light (e.g. an eye examination or
treatment).
The device allows to illuminate the eye with two different white
tones using the VarioLight function.
The cold white VarioLight can offer an advantage when examining
transparent media in the anterior segment of the eye, while the
warm white VarioLight creates natural image effects when viewing
circulated tissue e.g. in the posterior segment of the eye. The time
required to exceed the ISO 15004-2:2007 guideline is reduced to
48 seconds if cold white VarioLight is used exclusively, compared
with 88 seconds if warm white VarioLight is used exclusively.
