such as strabismus, anisocoria, ptosis, and buphthalmos, as well as to
measure lid position & eye aperature.

Taking a Session
A. Select Eye Check or Contact Lens icon as required. Input

In Contact Lens Mode, if sticker available, long-press IPD field
to enable sticker detection. IPD input not required if sticker
present.
B. Select Eye icon to start session. After a short pause, zoom

C. Frame subject until face fills about two thirds of the screen.
Use both hands to stabilize camera. Ensure patient’s eyes are
within the white indicators which appear on the screen.

Lens mode, or to the off-centre LED fixation target when
using Eye Check mode. Activate the off-center LED fixation
target as needed with left finger.
E. Half-press shutter button with right finger until green focus
locks. The position of the focus lock display on the screen is
random. If you are at the correct distance from the patient and
a red circle appears, do not change the distance. Simply lift
your right finger from the shutter button and re-focus until a
green circle appears.
Note2: Small green circle on the right hand side will indicate focus is
locked. Large red circle indicates patient too close while a small red circle
indicates patient too far.

shot – do not linger. Ensure patient is looking at the correct
location as picture is taken. Volk Eye Check will indicate what
to do next.

automatically recalibrate the lens after 4 pictures, if necessary.
