PRK and Refractive Lens Exchange
What is PRK?
Photorefractive keratectomy, or PRK, is another type of laser eye surgery used to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. While LASIK involves creating a thin flap in the cornea, PRK removes the outer layer of the cornea called the epithelium.
The PRK surgeon then uses a laser to reshape the underlying corneal tissue, allowing light to focus more directly on the retina and providing clear vision. The epithelium grows back over the treated area within a few days following PRK surgery.
Vision recovery after PRK tends to be more gradual compared to LASIK, with most people achieving optimal vision within a few weeks to a month. PRK may be recommended for patients with thinner corneas or certain corneal conditions that make them poor candidates for LASIK.
What is Refractive Lens Exchange?
Refractive Lens Exchange, or RLE, is a procedure that involves removing the eye’s natural lens and replacing it with an artificial intraocular lens (IOL) to correct focus errors. While it is similar to cataract surgery, RLE is performed to achieve sharper focus and reduce the need for glasses or contacts even when cataracts are not present.
There are many IOL options available, including monofocal, multifocal, and toric lenses. Your eye doctor will recommend the best IOL option for your individual needs and goals. Most people who have Refractive Lens Exchange experience a relatively quick visual recovery and are able to resume normal activities within a few days.
A thorough evaluation and discussion with your eye surgeon can help determine if you are a good candidate for Refractive Lens Exchange.
