PRK (Photorefractive Keratectomy) is a laser vision correction procedure that can effectively treat myopia, hyperopia, and astigmatism. PRK achieves vision correction in the same basic way that LASIK does, with one significant difference: PRK does not create a corneal flap. Instead, PRK removes the entire surface layer of your eye (the epithelium) using in order to reshape the stoma layer beneath it. After PRK surgery, the epithelium layer will regenerate and heal on its own.
Because of this, PRK is a good option for patients who have corneas that are too thin for LASIK flap creation. The ideal PRK candidate should:
- Have good ocular health
- Be 18+ years old
- Have a year or more of stable eye examinations
- Not be pregnant (or planning a pregnancy in the near future)
Since the epithelium layer is entirely removed during PRK treatment, your recovery period will last longer than the healing period for LASIK, but PRK is capable of achieving the same quality of results. Anesthetic eyedrops are used to keep you comfortable during the procedure, and you will be provided with post-surgical eyedrops to help manage any lingering discomfort. Unlike LASIK, there is no need for a blade to be used on your eye.
