PRK: A Safe and Effective Laser Vision Correction Option

PRK (Photorefractive Keratectomy) is a laser eye surgery designed to treat refractive vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Like LASIK, PRK works by reshaping the cornea using an excimer laser, which helps light focus correctly on the retina, leading to improved vision. However, unlike LASIK, PRK does not involve creating a flap in the cornea, making it a suitable option for patients with thinner corneas or those who have certain eye conditions.

In the PRK procedure, the outer layer of the cornea, called the epithelium, is removed to allow the excimer laser to reshape the corneal tissue underneath. After the laser treatment, a bandage contact lens is placed on the eye to protect the cornea as it heals. The epithelium naturally regenerates in a few days, and most patients begin to notice significant improvements in their vision within one to two weeks, though full recovery may take up to a few months.

One of the main benefits of PRK over LASIK is that it avoids the creation of a corneal flap, which can lead to complications in some cases, such as flap displacement or infection. Additionally, PRK may be a better option for individuals with thin corneas or those who participate in contact sports, as there is no flap to worry about. The procedure is also a good alternative for patients with dry eye syndrome, as the risk of exacerbating dry eye symptoms is lower compared to LASIK.

While PRK has a longer recovery time compared to LASIK, the procedure is still highly effective, with most patients achieving 20/25 vision or better. As with any surgery, there are potential risks and complications, including infection or undercorrection, but these are rare. PRK remains a reliable and safe option for individuals seeking to reduce or eliminate their dependence on glasses or contact lenses.
