surgery.
Brightness control
For this reason, the brightness of the light source in Carl Zeiss systems is con-
tinuously variable. This permits the surgeon to optimally adapt the light inten-
sity at the patient's eye to the conditions existing in each case.
Angle of illumination
A number of publications
1)-4)
suggest that the microscope should be tilted to
reduce the exposure of the macula to direct illumination.
Tilting mechanism
The surgical microscope features a tilting mechanism for the main microscope
to enable indirect illumination.
Focus of the light source
Studies show that injuries are likely to occur if the filament of the light source
is imaged on the patient's retina. The peak intensity of a filament is consider-
ably higher than that of an even and extended light source such as a light
guide.
Fiber optic illumination
This is the reason why Carl Zeiss uses fiber optic illumination in its surgical mi-
croscope systems.
