How to do eye steering
1. Ask the patient to keep their head in position between eye steered directions.
2. Click either Right Eye (OD) or Left Eye (OS) to select the eye you want to capture. Capture the on-
axis image (indicated by the green fixation light) first.
3. Click the same eye again to prepare the system to capture the next image.
4. Align the patient with the green fixation light. Explain that the green fixation light will go out and a
red fixation light will appear. Tell the patient which direction they need to look to see the red fixation
light. Select the required eye steering direction:
l
To see more of the 12 o'clock area of the retina you need to select the 12 o'clock direction.
l
To see more of the 9 o'clock area of the retina you need to select the 3 o'clock direction.
l
To see more of the 6 o'clock area of the retina you need to select the 6 o'clock direction.
l
To see more of the 3 o'clock area of the retina you need to select the 9 o'clock direction.
5. Ask the patient to look towards the new red fixation light. It is important that the patient does not
move their head.
6. Fine tune the alignment.
7. Ask the patient to open their eyes wide and to stay still. Press the capture button on the hand
control.
8. Repeat from step 3 for other directions.
