Laser treatment of the cornea

What does the PTK procedure consist of?

The Phototherapeutic Keratectomy procedure is performed using an excimer laser based on the photoablation method. It involves the removal of the epithelium and some corneal tissue. The laser works only on the surface of the cornea, so it does not interfere with its deeper structures.

The effect of the treatment depends on the type and severity of the condition with which the patient comes in.

The procedure is carried out under local anesthesia (drops). The entire procedure, including preparation and rest, takes about 20-30 minutes. The first follow-up visit takes place after a week.
