TransPRK - Epi-Lasik - Epi-K - Lasek - PRK

PRK is short for Photorefractive Keratectomy

This term is commonly used for a "Surface" excimer procedures where the first layer of the cornea, namely the "epithelium" is removed and the excimer laser is applied to the remaining cornea.
This means "non-lasik", that is without cutting any flap.

Our preferred method of applying excimer treatment is now TransPRK where the full procedure is performed via the Excimer laser.

In Epi-Lasik or Epi-K, a special microkeratome or separator is used to remove the epithelium from the surface of the eye and then the excimer treatment is then  applied.

If the separator si contraindcated, the epithelial layer can be removed with alcohol, in a procedure called LASEK.

These methods are referred to as ADVANCED SURFACE ABLATION.
The advantages of this method is that we avoid any flap complications and the results are generally better than regular surface PRK treatments.

"Regular" PRK, involves "scraping" off the epithelium prior to applying the excimer laser treatment.
