In patients with corneal thickness below a certain minimum, performing LASIK would be unwince, because "the" foundation "may not go back to its the world, agree on when not do to LASIK, like when the cornea is very steep or very flat. In those cases we feel strongly that advanced surface ablation or (PRK) would be the preferred procedure.
This procedure involves sculpting the cornea at the surface. This is done by removing the epithelium, (the film-like protective outer layer of the cornea) using a special instrument called Amoils epithelial scrubber. The underlying Bowman & # 39; s membrane (the micro-thin second tissue layer of the cornea that lies just below the epithelium, or outer layer) is exposed.
A bandage soft contact lens, is placed afterwards to maintain comfort in the eye . Oral vitamin C along with steroidal and non-steroidal, anti-inflammatory drops are prescribed. Patients are asked to wear dark UV protective glasses.
With the early days, PRK was very painful and vision was not good. With dvanced surface ablation there is minimal pain and most patients resume work in 3-4 days .
