OPERATIONS IN USE
OPERATION OF THE STEREO VARIATOR: OFFISS, OFFISS Lite
Binocular observation of observing the eye ground through the front lens may be difficult, as the
patient’s cornea is small. In such a case, use the variator.
1
Move the stereo variator lever to the right to set the stereo variator to IN.
Adjusting the stereo variator to IN provides an acute stereo angle for binocular observation.
This reduces the shading caused by the cornea, even for microcoria patients.
While the stereo variator is under the IN condition, the -2° illumination cannot be used.
When the front lens is not used, set the stereo variator to OUT.
2
Move the stereo variator lever to the left to set the stereo variator to OUT.
