CLAT™
Corneal Lamellar Ablation for TransplantationThe surgical process consists of placing a laser-opaque mask onto the operative site serving to create a vertical transition from bed to untreated cornea.
The constant frequency per area ablation begins at the deepest point (peripheral) and accelerates towards the center. Even though the ablation depth in the periphery may exceed 700 microns, due to the 1 KHz frequency, the total ablation time is typically 90 to 120 seconds in duration leaving a residual uniform thickness selected by the surgeon.
A beautifully smooth receiving bed results ready for the donar lamella. The smooth character of the bed is significantly different than is seen with laser or mechanical keratomes or manual disection.
