In Advanced Surface Ablation, the cornea is reshaped by the Excimer Laser from the surface rather than under a corneal flap like in LASIK.

PRK Step 1

Step 1:

The most superficial “skin” layer of the cornea (epithelium) is removed.

PRK Step 2

Step 2:

Excimer Laser with eye tracking is applied to reshape the cornea to correct the refractive error.

PRK Step 3

Step 3:

A contact lens is placed onto the eye for 5-7 days to allow the epithelium to grow back.
