Height between the liquid
in the drip chamber and
the top of the artificial
chamber: around 1.20 m
Positioning the graft on the artificial chamber:
If desired, apply cohesive viscoelastic to the endothelium.
RECOMMENDATION: Use grafts with a rim having a minimum diameter of 16mm and a well-centered cornea.
Donor graft cut:
Main steps:
• remove the epithelium and dry the corneal surface
• measure corneal thickness
• if derised, check the pressure with a tonometer
• place the guide ring for CBSU head on the cover and screw it on with the blue screw
• make the cut(s) with the CB turbine and the appropriate CBSU heads (see document "CBSU Head
Selection for Creating Ultra-thin Corneal Lamellar Grafts" #65082)
Removal of the graft and disposal of the devices:
Once the cuts are completed, unscrew the guide ring.
To prevent a possible collapse of the graft, open the chamber stopcock, unscrew the white screw, and gently lift
the cover to grasp the graft.
The graft is now ready to be placed on a Moria punch to obtain the desired diameter.
At the end of the surgical procedure, discard the single-use artificial chamber and its accessories, the CBSU head,
and the single-use tubing into an appropriate container for disposal (according to the regulations in force).
CAUTION for USA only: US federal laws restrict this device to sale by, or on the order of, a physician.
Use the syringe to gently infuse the system with corneal storage medium or BSS.
Position the donor graft on the top of the piston, endothelium downwards. Slightly lift
the graft with forceps to remove the possible air bubbles.
Precisely center the cornea on the stage and place the cover carefully in position
(inserting the pin into the slot). Check that the graft is well centered. Seal the
chamber by placing the white locking ring over the cover.
Open the chamber stopcock at least three seconds. Then, close the chamber
stopcock to maintain pressure of 90 mmHg. Check the 2 stopcocks are closed.
If desired, check the pressure with a tonometer.
Raise the IV bottle to a height of 1.20 m between the drip
chamber and the top of the artificial chamber (cornea) to
ensure obtaining pressure of 90mmHg.
Attach the IV bottle to the IV line. Open the air valve.
Purge the line, and use the roller to close the system.
Check that there is no air bubble in the IV line up to the
chamber.
Attach the IV line to the chamber stopcock and release
the roller of the IV line while keeping the chamber
stopcock closed.
