Procedure
Caution!
–
Avoid looking directly into the light source, e.g. into the microscope ob-
jective lens or into the light guide!
–
When selecting the brightness level for the patient's eye, always take
care to keep the strain on the patient's eye to a minimum.
–
If the red reflex is not necessary, move the retinal protection device
into the beam path. Only use the retro-illumination contrast stop, if the
surgical procedure requires a red reflex.
–
When operating on the eye, always use a GG 475 eye protection filter
to ensure that the patient's retina is not exposed to unnecessary (blue)
radiation (retinal injury)!
•
Switch on the power switch of the suspension system.
•
Start with the lowest brightness setting on the suspension system and
gradually increase brightness up to the necessary and still admissible
level.
•
Check the system using the checklist.
•
Swing the surgical microscope over the surgical field into an ergonom-
ic position within the working distance.
•
Press the actuator button on the X-Y coupling.
–
The X-Y coupling adopts its center position.
–
The focus adopts its initial position in the focusing range.
•
Select the lowest magnification (zoom function on the foot control pan-
el).
•
For coarse focusing, look through the eyepieces and lower the surgi-
cal microscope using the suspension arm until the surgical field comes
into focus.
•
Select the highest magnification (zoom function on the foot control
panel).
•
Look through the eyepieces and activate the focusing function on the
foot control panel until the microscope is sharply focused on the sur-
gical field.
