L WARNING! Danger of injury due to contaminations!
There must be no air bubbles, excess fluids, etc. between the PI 125 and the
corneal surface. This situation may impair the treatment and cause severe
patient injuries.
5.
Check if there are air bubbles, fluids, 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, fluids, or impurities between the PI 125 and the
cornea, undock the patient.
n
If the PI 125 is clean, continue with step 8.
6.
Repeat steps 1 to 5 until no air bubbles, fluids, or impurities are visible
between the PI 125 and the cornea.
7. Verify that there is no water ring between the PI 125 and the cornea.
n
If there is a water ring, undock the patient and use a Merocel
®
sponge
to absorb excess fluids. Repeat steps 1 to 7.
8. Verify that the eye is correctly centered.
9. Verify that one of the (more central) green or yellow shear force LEDs on
the force display is illuminated.
n
If not, correct the pressure by using the joystick (Fig. 132/1 or
Fig. 133/1) until one LED is illuminated green or yellow.
10. Close the suction clip by pressing the ends of the suction clip together.
ð
The patient is docked to the PI 125.
11. Verify again that one of the (more central) green or yellow shear force LEDs
on the force display is still illuminated.

For all other procedures using a headrest with external joy‐
sticks
1. Move the patient bed using the X/Y-joystick (Fig. 134/1) of the patient bed
control until the suction clip and the PI 125 are aligned.
2.
Slowly move the patient bed upward using the Z-joystick (Fig. 134/2) until
the suction clip almost touches the PI 125.
3.
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.
