Operation; Lamellar Resection On A Donor Eye (Graft) - MORIA CBm-ALTK CBSU Manuel Utilisateur

7 OPERATION

7.1 LAMELLAR RESECTION ON A DONOR EYE (GRAFT)

ACTIONS
1. Check the equipment before every use
• It is essential to make sure that the equipment is
perfectly clean and that it presents no debris, particle,
oxidation or deposit.
2. Connect the CB turbine to the console
• Check the pressure delivered by the console at the
turbine (operating range between 2.5 and 3.5 bars).
4. To prepare the donor eye:
• Mount the CB turbine on the ALTK artificial chamber or
on the single-use artificial chamber.
5. Activate the vacuum by pressing once on the "Vide /
Vacuum" pedal.
6. Check the intraocular pressure with a tonometer
• Moria recommends a pressure of 90mm Hg.
7. To prepare the donor eye:
• Lubricate the sliding guides for the ring for the artificial
chamber, the head and the blade.
8. Activate the oscillation of the blade and perform the
resection
• Once the microkeratome is in position, activate the
vacuum and the oscillation of the blade by pressing and
holding down the "Avance / Forward" pedal.
• Rotate the microkeratome gently and smoothly by hand
until a free corneal flap (or "free cap") is created.
• Depending on the thickness of the desired graft, a
second cut may be made.
Note that on the ALTK chamber (#19161) it is possible to
adjust the diameter by using lenses #19165 & #19166.
The adjustment ring on chamber #19162 allows the
diameter of the cut to be adjusted.
8. Release the vacuum by pressing once on the "Vide /
Vacuum" pedal.

• See the user guide for the console employed before
use.
• See the ALTK artificial chamber User Guide for
microkeratomes ONE & CBm-ALTK (#65009) before
use.
• See the selecting guide for CBSU heads for artificial
chambers (#65082).
• Check that the equipment does not interfere with other
medical equipment used during the surgery.
• For CBSU heads for artificial chambers: see the
selecting guide for CBSU heads for artificial chambers
(#65082).
• Before use, lubricate the various elements with
physiological serum or any other appropriate
ophthalmic solution.
• The equipment must not be in contact with a solution
with unknown interactions.
• See the user guide for the console used.
• See the ALTK artificial chamber user guide for
microkeratomes ONE & CBm-ALTK (#65009) before
use.
• See the selecting guide for CBSU heads for artificial
chambers (#65082).
• Check that nothing interferes with the movement of the
head in the ring sliding guides of the artificial chamber.
• At the end of the procedure, discard the CBm blade or
single-use head (CBSU) as well as the vacuum tube,
into an appropriate container.
