The PRK Procedure
1. Your eyelids will be cleaned.
2. Anesthetic drops are given to completely numb the eye for comfort and a lid holder is used to keep your eyelids open.
3. A solution is placed on the corneal surface to loosen the epithelium or top corneal layer.
4. Your surgeon uses information from your extensive testing to set a surgical plan that is programmed into the laser. The computer calculates the required treatment and directs the laser. Computer-controlled pulses of cool laser light are applied to the inner layers of your cornea. The inner corneal layer is reshaped with the laser to mimic your contact lens or glasses prescription.
5. The surgeon gently places a therapeutic bandage lens, like a contact lens, on the corneal surface until it heals. This minimizes discomfort after the procedure.
There are three different types of PRK: Conventional PRK, CustomVue PRK, or Allegretto PRK.
