It comes with one diode and special optics which is homogenizing the beam. Thus hot spots are being avoided and the endothelium is suffi ciently protected. To offer more fl exibility, it enables the surgeon to choose between three energy levels: 3 mW, 9 mW and 18 mW. This allows the surgeon to choose the ideal energy/time combination for the intended treatment: Standard - Accelerated - Express Cross-linking. At the end of the procedure the system switches off automatically.
3 mW x 1800 sec (30 min) = 5400 mJ
9 mW x 600 sec (10 min) = 5400 mJ
18 mW x 300 sec ( 5 min) = 5400 mJ
Since the total dose of radiation is time dependant, each setting delivers a total energy of 5400 mJ. Studies performed by Prof. Eberhard Spoerl, PhD at the University of Dresden demonstrated that the amount of cross-links achived by various energy levels is practically the same. To guarantee the high level of safety the beam of the CCL-VARIO has a wasteline at a distance of 45 mm from the optics and a depth of focus of approx. +/- 5 mm. To protect the limbal stem cells and to focus the beam on the clear cornea only the CCL-VARIO has a continuously adjustable aperture from 7 mm to 11 mm. The CCL-VARIO is portable with a table mount and comes in a sturdy transport case allowing the surgeon to be mobile.
