PRK (Photorefractive Keratectomy)
PRK is an alternative to LASIK. Jenkins Eye Care offers both, but some patients, worried about the corneal flap made during LASIK surgery, opt to correct their vision with PRK, the original form of laser eye surgery.
Both PRK and LASIK take only a few seconds to perform. Patients may feel some pressure, but no pain. The laser permanently corrects vision for patients with nearsightedness, farsightedness and astigmatism by changing the curvature of the cornea so that images are properly focused in the eye. In either procedure, you’ll benefit from less dependence on and often complete freedom from glasses or contact lenses.
The main difference between the two methods is that during PRK, the laser is applied directly onto the corneal surface, so the cornea is never cut. However, because the cornea is treated directly, you should expect to experience more post-operative pain than with LASIK. PRK also has a longer recovery time – one or more weeks – before your vision is restored. People with very thin corneas or with certain pre-existing conditions are more suitable for PRK. Dr. Jenkins can best advise which method is right for you.
What to Expect During the Procedure
PRK takes only about 5 minutes per eye to perform. For those few minutes, you will be laying back in a comfortable reclining chair with your head just under the laser equipment. First, the doctor anesthetize your eyes with drops, then, to keep you from blinking, place an eyelid holder in your eye. An outer layer of the cornea is removed to prepare the cornea for the laser. After that, you’ll be asked to look at a red target light. A computer system constantly tracks the patient’s eye position as they laser works. The laser delivers a cool pulsing beam of ultraviolet light, making a clicking sound as it works, and is completely painless, though you will feel a pressure. When both eyes are done, the surgeon will place a clear bandage contact lens on your eye to help keep you comfortable while they heal.
PRK offers permanent results, but it’s not for everyone. The professionals at Jenkins Eye Care can help. Call (855) 522-2020 to learn about your options.
