Chapter 3 - How to...
1. Prepare the device for image capture, see How to prepare for image capture on page 36.
2. Align the patient, see How to align the patient on page 37.
3. Ask the patient to open both eyes wide, and to look at the center of the alignment target. Using the live
SLO image, center the cross hairs on the pupil until the target is aligned and turns green.
4. Capture the image either manually or using auto-capture.

Auto-capture: Auto-capture is enabled when Automatic is shown in green on the touch screen.
The system captures an image when the scan head is correctly aligned. You can press the
screen to manually capture the image. Auto-capture is turned off after capturing an image.
l
Manual capture: Align the scan head into the correct position. Press the screen to capture the
image when the pupil is in the center of the cross hairs and the patient alignment target is
green. You can also capture using the hand control.

3. If required, remove the controls from the view by selecting Declutter .
