The PRK method is very effective in correcting small degrees of myopia, with or without astigmatism, but also to greater degrees if the cornea is relatively thin. A very thin laser beam is applied to the surface of the cornea.
In this technique, the corneal flap is not created, but the surface membrane of the cornea (epithelium) is removed, with a special tool and then the treatment with the Excimer Laser is applied.
A contact lens is placed at the end of the operation to help the epithelium heal within the next three to four days.
The operation is short and is performed using local anesthetic eye drops.
All individualized treatments can be applied to this method.
