Illumination intensity
The majority of researchers suggest that the surgeon should use the lowest
light intensity that is necessary at the patient’s eye to guarantee good viewing
during surgery.
Brightness control
For this reason, ZEISS has addressed this aspect by equipping its devices
with a feature for continuously varying the brightness of the light source.
This permits the surgeon to optimally adapt the illumination intensity at the
patient’s eye to the conditions existing in each case.
Angle of illumination
Several publications
1)-4)
suggest tilting the microscope to reduce the exposure
of the macula to direct illumination.
Tilting mechanism
The surgical microscope features a tilting mechanism to enable indirect illumi-
nation.
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, e.g. a light guide.
Fiber optic illumination
For this reason, ZEISS uses fiber optic illumination in its microscope systems.
