OPERATING PROCEDURES: AR (refractive error) and KM (corneal curvature radius) Measurements

1 Instruct the patient to look through the measuring

window and watch the center of a picture of a balloon

without straining as he or she sees it.

2 Manipulate the joystick to display the

patient’s eye on the screen.

By pulling the joystick backward, pushing it

forward, tilting it to the left and right, the main

body moves back, forth, to the right, and to

the left. By turning the upper part of the joy-

stick, the main body moves up and down.

Align the device to the patient’s eye with right,

left, up and down movements, and adjust the

focus with back and forth movements.

3 Perform alignment and focusing.

The methods of alignment and focusing vary

according to the 26. TRACKING SW parameter

setting.

*See “{ Auto-tracking mode and auto-shooting mode (

page 36) for details.

Perform alignment by placing the mire ring

reflected by the patient’s eye in the center of the

target.

Perform focusing according to the indication of

the on-screen focusing indicator.

• If the mire ring is not in the center of the pupil and the min. pupil mark is on the iris, turn off

the auto-tracking function and bring the min. pupil mark into the center of the pupil to

perform measurement, ignoring the mire ring.

• Auto-tracking or auto-shooting may not work on keratoconus or postoperative cornea.

In such a case, turn off the auto-tracking and auto-shooting functions.
