During the calibration, a suggested target will be displayed with a large red dot which will move in a
sequence of jumps from fixation point to fixation point, indicating the next desired fixation. With the
help of this display, the examiner can announce to which target the patient should be looking at.
Figure 4.2.3-3 Sequence of calibration fixations displayed in the Eye in Space plot at the bottom right of the
calibration screen. The sequence is: center, right, left, upper, lower. This sequence is repeated twice within a duration
of 24 seconds.
The calibration procedure wil automatically stop after about 24 seconds. If you wish to end the
calibration before, then select Stop.
Figure 4.2.3-4 Completed Standard Eye Calibration screen.
Evaluate the calibration: a successful calibration should form a cross with accumulations of gaze
points around the instructed laser points. A false calibration shows scattered gaze points and has to
be repeated.
