Your vision is an important part for an improved quality of life. Refractive errors are easily corrected through advanced laser surgery. Refractive vision problems include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (abnormal curvature of the cornea).\u00a0 Photorefractive Keratectomy (PRK) is an advanced laser surgery that helps correct your vision by reshaping your cornea (the transparent part of the eye covering the iris and the pupil that allows light to enter inside).\u00a0 PRK was the first refractive surgery\u00a0 that was given approval by the FDA (Food and Drug Administration).<\/span><\/p>\n

The goal of PRK is to allow less dependency on glasses and contact lenses. It is a flapless procedure that takes approximately 10 to 15 minutes per eye. PRK is a good option if you have corneas that are too thin for LASIK or have a curvature that might make creating a flap unsafe. PRK surgery results are considered to provide great improvement in your eyesight.<\/span><\/p>\n

Let’s explore how long you can enjoy the benefits of this revolutionary laser vision correction surgery.<\/strong><\/p>\n

What is Photorefractive Keratectomy?<\/b><\/h2>\n

Photorefractive Keratectomy, popularly known as PRK, is a refractive surgery that uses a laser to correct your vision. Refractive errors occur when your eyes do not refract (bend) light properly. Your eye surgeon uses a special brush or alcohol solution to remove the outer layer of the cornea (epithelium). Then an excimer laser is focused to reshape your cornea. This improves your vision by correcting the path of light so that it is focused on the retina (light-sensitive layers of nerve tissue at the back of the eye that receives and sends images to the brain through the optic nerve).. PRK surgery is an outpatient procedure which takesess than 30 minutes less than 30 minutes for both the eyes. Recovery is usually long which takes around 4 to 6 weeks. PRK reduces your dependency on eyeglasses and contact lenses. It is a good choice for you if you have dry eyes or thin corneas, since other laser surgeries are not recommended for such conditions.<\/span><\/p>\n

How Long Does PRK Surgery Last?<\/b><\/h2>\n

PRK is a trending refractive surgery which is also useful if you have thin corneas.\u00a0 The results last a very long time. It provides a permanent solution to the refractive errors present.\u00a0 Due to the innovation in technology over the years, eye surgeons can offer advanced treatment methods to improve your vision. Once the vision has stabilized 2 to 3 months post surgery, it is likely in most cases that your vision will remain stable. However, there could be small visual changes as the eye changes with age. Often this is seen over the age of 50. The most common age-related vision regression seen is cataract. This may affect your vision correction done during PRK surgery. Also, the PRK outcomes differ in each person since everyone has a different rate of healing.\u00a0<\/span><\/p>\n

Can You Have PRK Surgery Twice?<\/b><\/h2>\n

PRK enhancement procedure can be performed multiple times as long as the cornea remains healthy after healing. There should be adequate corneal thickness left for repeated enhancement surgeries. These are similar to the initial procedure. It involves removing the outer layer of cornea (epithelium) and reshaping the cornea with an excimer laser.<\/span><\/p>\n

Reasons that Affect Your PRK Results in the Long Run<\/b><\/h2>\n

You may experience a change in your vision after PRK a few months or years later. This may not always be due to side effects of the surgery. There could be some other underlying causes affecting your eye and vision.\u00a0<\/span><\/p>\n

        • \u00a0Hence vision problems occur due to cataract and not a side effect or after effect of the surgery.\u00a0<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
