3) Perform alignment in the Y axis. While pressing the center of the screen (3),
the measuring head advances towards the patient.
Touch the measuring
head retract button (4) to retract the measuring head towards the physician.
(Fig. 2)
4) When the focus indicator (5) appears while Auto Alignment is activated,
focusing in the Y axis starts automatically.
When alignment conditions are
optimal, the alignment OK mark (6) is displayed.
c) Positioning by the joystick
■ This instrument is designed to perform measurement in Auto mode to
ensure higher accuracy through standard operation. However, Auto
Alignment may not be particularly effective when insufficient light is
reflected due to deformation or inflammation of the cornea. In this case,
conduct measurement manually.
■ The reflection in the center of the cornea may not be clearly viewed when
any deformation and/or inflammation of the cornea is severe. In this case,
an error may occur even in Manual mode.
There are two types of operations - rough operation for roughly positioning the
measuring head and fine operation for finely adjusting the position of the measuring
head.
[Rough operation]
Moving the joystick moves the measuring head back, forth, left, and right.
When the up/down ring is slid up and down, the head moves up and down.
(Fig. 1)
[Fine operation]
Tilting the joystick moves the measuring head in the tilting direction.
Turn the up/down ring to move the head up and down. (Fig. 2)
