Photo-Refractive Keratectomy (PRK)

prk laser surgery

Photo-Refractive Keratectomy (PRK) involves no incision. The brief procedure is performed under topical anesthesia. The surgeon removes a thin surface layer called the epithelium, on the cornea. With computer controlled precision, the laser vaporizes microscopic amounts of tissue to sculpt a new corneal contour. Following the procedure, the doctor prescribes pain medications to control any discomfort that may last a few days.

The vision remains blurred for a number of days, until the surface cells have a chance to heal over the cornea, generally four days. Most of the side effects that may be experienced are part of the healing process of the cornea, and will usually disappear or be reduced within a few weeks or months after the surgery. Long-term complications are uncommon. The most common side effect of PRK is pain lasting four days following the procedure.Since LASIK and PRK are usually performed on Thursdays, most PRK patients take a four day weekend to heal up. On the fourth day the vision is usually not 20/20 but frequently good enough to drive and resume most activities. It takes about a month for PRK patients vision to catch up to where it would have been if they had LASIK. The reason for this is it takes a few weeks for the surface layer (the epithelium) to thicken up to it’s normal 5 cell layers thick and to become smooth again like glass. The visual results of PRK and LASIK are equal.

Dr. Wright was one of ONLY 10 SURGEONS throughout the United States chosen by Summit Technology to perform the Clinical Trials on which the FDA based the approval of the Excimer Laser (PRK). Immediately after approval, Dr. Wright was one of the first surgeons in Colorado designated to provide the clinical training to many of the other surgeons throughout Colorado in this procedure, making Dr. Wright an ideal choice for those seeking this type of eye surgery in Colorado Springs.
