37.
Click on the <
Ready
> button.
38.
Start ablation by depressing the footswitch.
39.
Stop every 15 seconds to verify proper centration.
40.
After the last shot, park the CCA+ unit.
Note
The progress bar display informs you of the treatment progress.
When the correction program has been finished, the control computer automatically stops laser
release. To interrupt the treatment, release the footswitch. To continue the treatment, step on the
footswitch again.
You can abort the treatment after releasing the footswitch by clicking the <
Abort
> button. If you
do not confirm the displayed query, you can continue the treatment as after an interruption. After
you have confirmed treatment abortion, you
cannot
resume the treatment.
Note
If the eye tracker loses track of the pupil during the treatment or the pupil leaves the hot zone, the
control computer will interrupt the treatment.
You can then continue the treatment with the <
Resume
> button, when the pupil has been
detected again or the eye tracker has been deactivated.
41.
Immediately after ablation, clean the stromal bed very carefully with a new moist triangular swab
moved clockwise and with another new moist swab moved counterclockwise to remove debris
and epithelial cells. Continue until the bed looks dry.
42.
Fold back the flap by means of a bent cannula. If folds have formed, use the cannula to unfold
them. Then, rinse with BSS to clean the site and remove any wrinkles.
Note
Rinse briefly at high pressure to avoid hydration of the flap and thus canalization -> ingrowth of
epithelium!
43.
Make sure the flap is properly positioned (marks, symmetry of the duct). If not, use the cannula
again. Then, using a wet triangular swab wipe the flap away from the hinge to fix its position.
Note
Use the segmenting facility of the ring lamp, if necessary, to check the correct position of the flap.
44.
Apply a few drops of an antibiotic.
45.
Wait one minute while keeping the central epithelium moist.
46.
Carefully remove the eyelid retractor and the drapes. Ask the patient to blink repeatedly and
observe the behavior of the flap.

Microscope setting: Magnification 0.6x.
