Photorefractive keratectomy (PRK) is a refractive surgery procedure performed to correct vision issues such as nearsightedness, farsightedness, and astigmatism. While the procedure did not receive FDA approval until 1995, it has been performed in other countries since the 1980s. Prior to the development of LASIK surgery, PRK was the most common refractive surgery procedure.
Dr. Wilmarth often recommends PRK as an alternative to LASIK. Many patients who are not good LASIK candidates due to corneas that are too thin or pupils that are too large may achieve excellent results with PRK. Patients with corneas that are very thin may experience complications with corneal flap creation during LASIK, ruling them out as a candidate. Patients with pupils that are very large have an increased risk of seeing starbursts or halos at night after undergoing LASIK. PRK can help you avoid these unwanted LASIK complications.
The best way to find out if PRK is the right vision correction option for you is to schedule a consultation with refractive surgeon Stephen Wilmarth, M.D., at our Sacramento office. Call today to get started: 916-782-2111. During your free consultation, Dr. Wilmarth will perform a thorough evaluation of your eyes before recommending the ideal procedure to help you achieve clear vision.
Difference between LASIK and PRK
Both PRK and LASIK are performed to treat the same refractive errors in vision, but each procedure takes a different approach to reshaping the cornea. In LASIK, a hinged flap is created in the surface of the cornea that is used to reshape the underlying tissue. PRK does not require the creation of a flap in order to reshape the cornea.
Instead of creating a flap during PRK, the surface layer of the cornea is completely removed, allowing Dr. Wilmarth to reshape the underlying tissue with an excimer laser.
What to Expect after PRK Eye Surgery
During the PRK recovery period, the surface layer of the cornea will heal. As a result, the healing time for PRK is a little longer than for LASIK, and you may experience a little more discomfort. But you will be able to achieve excellent vision with both procedures.
PRK is a very effective way to correct refractive errors in vision. Approximately 95% of patients are able to see clearly without glasses three months after the surgery is complete. While it may take a little longer to achieve your results with PRK than with LASIK, the procedure is well worth the investment if you are not a good candidate for LASIK.
