HFA3 Instructions for Use
1. Touch the center of the pupil in the Live Eye monitor, or use
the manual chin rest switch, to move the chin rest and align
the eye to the center of the lens target, indicated by a green
plus sign "+".
The eye is centered when the "x" of the pupil turns green and
is overlaid on the green plus sign "+", resulting in a green star
.
2. Ask the patient if the fixation light is in focus. If the fixation
light is out of focus you may need to adjust the refractive
correction.

Note: The HFA3 saves the last chin rest position for each
patient eye for a particular patient and uses the saved chin rest
position at the start of each eye exam.

Note: When using Liquid Trial Lens on HFA3 Model 860, move
the lens close to the patient's eye but avoid hitting lashes. If
the lens is too close to the eye, the eye appears too dim on the
monitor and may adversely affect Gaze Tracking.
3. Read the instructions shown on the screen to the patient.
The Back button returns to the previous screen. Select Next or
Start Test to proceed.
