A Comprehensive Guide on PRK Eye Surgery by Boston Vision
Photorefractive Keratectomy (PRK) is an advanced laser eye surgery that has helped countless individuals achieve clearer vision without needing glasses or contact lenses. Boston Vision offers PRK a safe and effective alternative to LASIK, especially for those with thinner corneas or certain cornea conditions. This blog will delve into PRK surgery, including what it entails, candidacy criteria, the procedure itself, recovery expectations, and the consultation process.
What is PRK?
Photorefractive Keratectomy (PRK) is a type of refractive surgery that corrects vision by reshaping the cornea using a precise excimer laser. Unlike LASIK, PRK does not involve creating a corneal flap. Instead, the outer layer of the cornea (the epithelium) is removed to expose the underlying tissue, which is then reshaped to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. This approach is particularly beneficial for individuals with thin corneas or those who are not suitable candidates for LASIK. PRK has been proven to be a highly effective procedure, providing long-lasting vision correction and a reduced risk of complications associated with corneal flaps.
Am I Suitable for PRK?
Determining suitability for PRK involves a comprehensive eye examination and consultation with a qualified ophthalmologist at Boston Vision. Ideal candidates for PRK are typically over 18 years old, with stable vision prescriptions for at least one year. PRK is especially suitable for individuals with thin corneas, irregular corneal shapes, or those participating in contact sports or activities that put them at risk for eye injuries. Additionally, candidates should have healthy eyes, free from conditions such as severe dry eye, cataracts, or glaucoma. Patients must have realistic expectations and understand that while PRK can significantly improve vision, it may not eliminate the need for corrective eyewear in all situations.
PRK Procedure
The PRK procedure is relatively quick and usually takes 12 minutes for both eyes. On the day of the surgery, numbing eye drops are applied to ensure comfort. Your ophthalmologist, Dr. Samir Melki, then carefully removes the cornea’s thin outer layer (the epithelium). Once the epithelium is removed, the excimer laser is used to reshape the corneal tissue, correcting the refractive errors. The laser is guided by detailed measurements of the patient’s eye, ensuring precise and customized treatment. After the laser reshaping is complete, a protective contact lens is placed over the cornea to aid in healing. This contact lens is typically worn for about a week until the epithelium regenerates.
PRK Recovery and Results
Recovery from PRK is a gradual process, with most patients experiencing noticeable improvements in their vision within a few days. However, it can take several weeks to achieve optimal vision clarity. Patients may experience mild discomfort, light sensitivity, and blurry vision during the initial recovery period. It is essential to follow the postoperative care instructions provided by Dr. Samir Melki, which may include using prescribed eye drops to prevent infection and promote healing. Most patients achieve significant vision improvements and are satisfied with the results of PRK. The outcomes are comparable to LASIK, with many individuals attaining 20/20 vision or better.
