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.
