OPERATION PROCEDURES
* Follow the same procedure for the other ocular.
* Denote the diopter values on each ocular for future reference.
(4) Interpupillary distance adjustment
While looking through the eyepieces at the image on the focusing test rod, adjust the converg-
ing binocular's prism box, so that the image is fused and a stereoscopic image results. For
operator’s comfort, since each eyepiece can be moved independently, insure that both eye-
pieces are at the same height.
PATIENT POSITION AND FIXATION TARGET
(1) Positioning patient's head
Have the patient place his chin on the chinrest and forehead against the forehead rest. Adjust
the chinrest adjuster so that the patient's outer canthus is at the approximate height of the
level marker.
