•
Using the brake tabs on the base, secure the stand in position. Make
sure that the stand is stable and cannot roll away.

Avoid looking directly into the light source, e.g. into the microscope ob-
jective lens or a light guide.
•
When the illumination is on, the light guide must be connected at both
ends. Otherwise there is a risk of fire or burn injuries.
•
Any kind of radiation has a detrimental effect on biological tissue.This
also applies to the light illuminating the surgical field. Please therefore
reduce the brightness and duration of illumination on the surgical field
to the absolute minimum required.
•
When operating on the eye, always use a GG 475 protection filter to
ensure that the patient's retina is not exposed to unnecessary (blue)
radiation (retinal injury).

Always use the main power switch of the instrument to turn it off.
•
The main power switch must always be turned off when the instrument
is not in use.
Phototoxic retinal injury in eye surgery
General
Several papers have been published dealing with the problems of photo-
toxicity during eye surgery. A comprehensive review of these publications
reveals five aspects of particular concern:
–
Illumination characteristics (spectral composition)
–
Intensity of illumination
–
Angle of illumination
–
Focus of the light source
–
Exposure time to light
