What is photorefractive keratectomy (PRK)?

Photorefractive keratectomy is a no-flap alternative to LASIK. 

The PRK laser gently removes the outer layer and reshapes the cornea. PRK gives the patient safer surgical options while still providing the same laser technology and outcomes as LASIK. 

This procedure avoids the cutting of a flap on the corneal tissue which in return minimizes potential flap complications in the future. The cutting of the flap increases the risk of intraoperative complications, and it can also cause increased dryness in patients who already have dry eyes before the procedure.

The surgeon can treat the corneal surface to correct nearsightedness, farsightedness, and astigmatism.
