A possible alignment sequence to center the eye is shown Figure 4-4.
Figure 4-4 Centering the pupil in the image with a sequence of three camera rotations. Immediately after the goggles are placed on
the patient, the eye can assume a position as in the upper left image. From this starting position, the camera first needs to be
rotated such that the pupil is centered horizontally. The red arrow in the top left image indicates how the pupil will move during such
