9.4.4.2
For capsulotomy and lens fragmentation procedures using a
headrest with external joysticks
1.
Move the patient bed using the X/Y-joystick (Fig. 134/1) of the patient bed
control panel 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 using the Z-joystick (Fig. 134/2) 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.
L
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.
6.
Check if there are air bubbles or impurities between the PI 125 and the
cornea.
It may be useful to change the camera focus between the lens and the cornea
to better recognize air bubbles.
n
If you see air bubbles or impurities between the PI 125 and the cornea,
undock the patient.
n
If the PI 125 is clean, continue with step 9.
7.
Clean the PI 125 with a Merocel
®
sponge to remove the impurities.
n
If the PI 125 is not clean, dispose of the product and use a new PI 125.
8.
Repeat steps 1 to 7 until no air bubbles or impurities are visible between
the PI 125 and the cornea.
