Illumination system
The illumination system has been designed for use in ophthalmology. A
light guide directs the light from the light source in the suspension system
to the surgical microscope.
A retinal protection device is provided to protect the patient's eye from
photoretinitis. This device can be swung into the beam path if no red reflex
is required.
At the light source integrated in the suspension system, a GG 475 eye
protection filter can be swung into the beam path. This filter markedly re-
duces the exposure of the patient's and surgeon's eyes to light.
Warning!
–
Avoid looking directly into the light source, e.g. into the microscope ob-
jective lens or into the light guide!
–
Adjust the intensity of the illumination of the patient's eye through the
surgical microscope in such a way that the fundus is exposed to as lit-
tle light as possible.
–
If no red reflex is required, swing the retinal protection device into the
beam path. Only use the retro-illumination contrast-enhancing stop
(see page 64) if the procedure requires a red reflex.
–
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 (risk of retinal injury).
