PRK (photorefractive keratectomy) is designed to correct vision problems like nearsightedness, farsightedness and astigmatism. PRK is a type of laser eye surgery and can be a good alternative to a LASIK procedure. PRK uses the same precise excimer laser technology to correct vision as LASIK but without a protective flap being created. PRK is commonly referred to as surface ablation as the corneal reshaping is done on the surface of the eye. PRK is completed in 10 minutes or less. To ensure optimal patient comfort patients are given a relaxing medication by mouth and numbing eye drops are applied before and during the procedure. Dr. Lee begins by removing the thin outer layer of the cornea with an alcohol bath in preparation for laser correction. Then you are asked to focus on a blinking red light while your cornea is gently reshaped to correct for your prescription using an excimer laser. Most treatments are completed within 5-60 seconds per eye. After desired correction has been obtained, a contact lens with no prescription is placed in the eye for about one week while the outer layer of the cornea heals. This corneal layer will regenerate itself over a few days and eye drops are used to help with the healing process. Most PRK patients return to normal activities after approximately 5-7 days. While vision will fluctuate from blurry to decent initially, vision quality will continue to improve over the next few weeks after your PRK procedure.
PRK was the first laser refractive surgery approved by the FDA, receiving final approval in 1995. With over 20 years of clinical achievement, PRK is extremely safe and effective. The procedure itself is painless and can be a suitable laser vision correction option for those seeking clear vision without the hassle of glasses and contacts. The quality of vision between LASIK and PRK are essentially identical. PRK has a longer visual recovery time, but offers surgical simplicity.
Some athletes and people with recreational or occupational activities that put them at risk for eye trauma might consider PRK at CS LASIK Institute. This may include those who participate in high contact sports, military service men and women, and those with careers in police or fire departments. The corneal flap created during LASIK doesn’t exist, therefore eliminating the risk of disrupting or damaging it. PRK is also a safe alternative for those whose cornea is too thin for LASIK or for those who have undergone LASIK previously and now have a thinner residual cornea. Your individual treatment needs and candidacy are carefully evaluated during a thorough complimentary consultation at our facility. Once you are deemed to be a great candidate for PRK, surgery can usually be completed within a few days or short weeks of your initial consultation appointment.
