Correct Patient Positioning
Set the height of the table so the canthus marks on the sides of the instrument are level with the
patient’s eyes.
Patients should lean forward slightly so that the center of their forehead rests in the middle of the
rubber forehead pad. The patient’s head should contact the headrest straight-on; perpendicular
to the front of the instrument (not turned to the side). In addition, the patient’s nose and chin
should be inward, towards the front surface of the unit.
Proper
Patient Alignment
(Chin Close to Unit)
Improper
Patient Alignment
(Chin Moved Away From Unit)
Observe the photo on the right. Notice the distance between the patient’s chin and the front of
the instrument. The instrument is too low, causing the patient to rest his head in a downward-
facing manner. In this instance, the patient may not be able to see the fixation target, and the
alignment system may not be able to find the patient’s eye.
