Patient Alignment Guide

Too far out

(Used for

opto

map alignment)

Correct positioning

Helpful tip

: Stay still and keep looking at the center of the cross hairs. Keep

both eyes wide open.

(Used for

opto

map. OCT uses only the center of the pattern.)

Too close

(Used for

opto

map alignment)

Note

: In some instances the operator may choose to capture an image when you are aligned to the blue or red

target, or when only the center is visible. When capturing OCT modalities the operator may choose to capture
an image when you are aligned slightly off center.
