Guidelines for Anterior Segment Cube 512x128 Scan Acquisition

• Instruct the patient to fixate on the center of the fixation target.
• Use the screen X, Y and Z controls or keyboard arrow keys and mouse scroll wheel to
center the scan on the corneal vertex with the anterior chamber visible in the B-scan
viewport.to center the scan between the gray bars on either side of the B-scan display,
as shown in Figure 6-5.
• If the patient's cornea is perfectly centered, a strong reflection from the anterior
cornea can produce bright artifacts in the HD Cornea display
alignment should be slightly offset from the center by adjusting the chinrest to avoid
the corneal reflection.
