What Type of Refractive Errors Can be Improved With PRK Surgery?
&srotate=0)
PRK (photorefractive keratectomy) is a groundbreaking laser eye surgery that addresses refractive errors like nearsightedness (myopia) and farsightedness (hyperopia). So, what is PRK and how does it differ from more well-known procedures like LASIK?
Dr. Ming Wang, Harvard and MIT (MD, magna cum laude); PhD (laser physics) understands the importance of making safe and informed decisions regarding vision correction. Call our Nashville eye center and schedule an appointment if you are interested in reducing your reliance on corrective eyewear. Wang Vision Institute can help determine if PRK is suitable for your needs.
How refractive errors impact your vision
Refractive errors cause blurry vision at different distances, and they occur when an improper eye shape prevents light from focusing on the retina. This makes everyday tasks like reading more challenging. Nearsightedness and farsightedness are very standard refractive errors, with most people turning to contact lenses or glasses to correct the problem.
LASIK is a popular way to reduce nearsightedness and farsightedness. This laser surgery involves creating a flap in the cornea to change its shape. But for some people with certain eye conditions, PRK may be a better option.
When to choose PRK for refractive errors
Photorefractive keratectomy also employs laser technology to reshape the cornea, but instead of creating a flap, it removes the epithelium of the eye. This thin tissue layer is discarded during surgery but should grow back within two weeks of the procedure.
Our Nashville eye center recommends PRK for individuals with thinner corneas or chronic dry eyes because flapless procedures minimize your risk of complications. It's also more suitable for people who are engaged in contact sports or other activities that involve hazards to the eyes. Dr. Wang can perform a full evaluation and recommend the appropriate vision correction procedure for your needs.
Additional considerations for determining your candidacy
Patients who undergo any procedure at Wang Vision Institute should be at least 18 years old and have had a stable prescription vision for at least one year. In addition, potential candidates must be in good overall health and have no eye diseases or infections that could impact the outcome of their surgery. Our Nashville eye center is equipped with state-of-the-art diagnostics tools and can determine the right way to move forward.
What about the results after PRK?
Laser eye surgery may cause sensitivity to light or a gritty feeling in the eyes for a short period after treatment. We ask patients to wear protective bandages for 5 – 7 days to reduce their risk of infection and help with healing. Follow-up visits are essential during the first few weeks so we can monitor your progress and help manage any discomfort.
Results depend on your refractive error, but most people can expect to reduce or remove their need for corrective eyewear after undergoing PRK. Optimal visual acuity occurs within 4 – 12 weeks. We take pride in providing high-quality care and helping patients achieve the best possible outcomes.
