OPERATIONS IN USE

Setting has been completed.
It is impossible to perform initialization (except X-Y translator), to change the illumination
angle, to perform the rough focusing operation or to adjust the illumination light intensity
with the foot switch.
It is possible to operate the variable illumination aperture and to perform the front lens
focusing operation.
Operating the front lens
1
Hold the microscope operation handle and press the electromagnetic lock release switch. Then
adjust the microscope position to condense the illumination light on the surface of cornea.
The distance between the cornea and the bottom of the front lens is approx. 20mm.
2
Let the illumination light enter through the center of cornea by using the X-Y translator lever switch.
3
If you see a flare (reflected light) in the observation visual field through the microscope, move the
front lens up and down with the front lens focusing switch until the flare disappears. The flare may
not disappear because of the difference between eyes or because of the IOL transplantation eye.
Operating the variable illumination aperture provides an observation image with better
contrast and less flare. (Refer to "OPERATION OF THE VARIABLE ILLUMINATION
APERTURE: OFFISS, OFFISS Lite" on P. 76.)
