For capsulotomy and lens fragmentation procedures using a
headrest with integrated joystick
1. Move the patient bed using the joystick (Fig. 132/1 or Fig. 133/1) of the
patient bed control panel at the headrest until the suction clip and the PI
125 are aligned.
2.
Instill a maximum of six drops of balanced salt solution (BSS) in the suction
clip.
3. Slowly move the patient bed upward until the suction clip almost touches
the PI 125.
4.
Be aware that the reflection of the laser ring light is visible in the video camera
image.
Ensure that the laser ring light illumination switch is adjusted to position
‘10’ (Fig. 12/1). Align the reflection of the laser ring light on the cornea with
the laser ring light and gently move the patient bed upward.
5. Slowly move the patient bed upward until the central cornea gently
touches the PI 125. Ensure that there are no wrinkles visible in the OCT
image.

CAUTION!
Ensure that the pressure status display does not reach the upper red
pressure display area! Otherwise there is a higher risk to have wrinkles
in the posterior cornea.
ð
The shear force display shows the lateral pressure that is exerted on the
eye. The optimal position is achieved when the LEDs are illuminated
green.
