What is Photorefractive Keratectomy?

Considering corrective eye surgery? Photorefractive Keratectomy (PRK) might be for you! Let your Boca Raton expert eye doctor at Mitchell Eye Center help you understand what PRK is, how it works, and what to expect after experiencing this treatment.

Photorefractive Keratectomy (PRK) is a laser-assisted vision correction eye surgery that reshapes the cornea. Like with LASIK and several other vision corrections an eye doctor can perform, PRK removes material from the inner layers of the cornea to compensate for myopia, hyperopia, and other vision abnormalities. Where these laser procedures differ, typically, is in the way the outer layers of the cornea are treated. With PRK, the outer layer is completely removed (usually with the assistance of the laser itself), and then the eye is allowed to heal on its own.

After the Procedure

When the PRK vision correction eye surgery is complete, bandage contact lenses are placed on the eye(s), helping to shield the cornea from infection and foreign material while the outer layers of the cornea heal and reform. Vision is typically obstructed while the outer layer heals, and patients occasionally report haziness, spots, and other vision problems anywhere from the first few days to several months after the eye surgery.

Facts about PRK

Thanks to the evolution of eye surgery technology, the PRK procedure only takes about 10 minutes, and PRK is considered generally as effective as LASIK when comparing vision correction at the six-month mark. Because the outer layer of the cornea is removed, there is a chance of scarring complications with PRK, but this is rare thanks to improved equipment. There is also the possibility of infection, so patients undergoing PRK need to protect their eyes during their recovery period. As mentioned, your Boca Raton eye doctor will use a bandage contact lens to help shield the cornea during this time. Full recovery from PRK may take a few days to several months.
