7.4.1.3 Internal Fixation Targets
The internal fixation target set positions include 9 fixed points to
steer a patient's gaze:
• Central
• Temporal
• Nasal
• Superior
• Inferior
• Superotemporal
• Superonasal
• Inferonasal
• Inferotemporal
You can override the preset fixation targets and choose any
location within the patient's field of view (See Manually Positioning
the Internal Fixation Target [} 122].)
If the patient is unable to see the fixation target, you can blink the
fixation target to help the patient to see it. (See Blinking the
Fixation Target [} 121].)
Internal fixation targets adjust to any point within the 90 degree
circular FOV.
