3.2.4.1 What to do after the image is captured
After you have captured the image, the image quality needs to be checked. You can then continue or
complete the session.
1. Check the image quality and laterality. Accept, change laterality or delete the image.
2. If required, continue capturing images.
3. Replace the dust cap when you have finished imaging each patient.
3.2.5 How to capture eye steered images
Depending on the features available on your device, you may be able to capture eye steered images.
1. Position the patient, see How to prepare for image capture on page 33.
2. Align the patient, see How to align the patient on page 33.
3. Ask the patient to keep their head still in the standard alignment.
4. Select the eye steered direction.
5. Ask the patient to look at the new alignment target, without moving their head. Align the scan head to
the eye steered alignment target. Make sure the patient can see the target, that the target is green and
that the cross hairs are close to the center of the pupil.
6. 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.

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.
