Typical procedure
•
•
Adjust the brightness on the stand by starting with the lowest value and
gradually increasing the brightness level. Please observe the maximum
permissible brightness (see page 26).
•
Adjust the eyepieces (see page 87).
•
Swing the surgical microscope over the surgical field into an ergonomic
position within the working distance.
WARNING Eye damage!
Looking directly at the light source, e.g. at the microscope lens or optical
fiber, can damage your eyes.
•
Never look directly at the light source!
CAUTION Retinal damage to the patient’s eye!
Excessive light intensity (brightness setting) or overly long radiation exposure
times may lead to retinal damage in the patient’s eye.
•
Adjust the illumination intensity and the resulting radiation exposure time
by selecting the appropriate illumination setting. You will find the values
recommended by ZEISS in the “Maximum radiation exposure times” table
on page 26.
•
When operating on the eye, use the retina protection filter (blue barrier
filter). It protects the patient’s eye against unnecessary (blue) radiation
and increases the recommended maximum radiation exposure time.
•
If no red reflex is required, swing the retinal protection device into the
beam path.
CAUTION Variable light intensity due to a faulty light source!
A faulty light source with variable light intensity can damage the patient’s
retina.
•
Check the light source and the brightness adjustment before each use of
the device.
•
Keep a backup lamp or an OR illuminator ready.
•
If the light control fails, switch the device to manual mode (see page 125).
