PRK (photorefractive keratectomy)

Photorefractive keratectomy (PRK) eye surgery in Yuma, Arizona, was at one time the most common laser eye surgery. It uses the same excimer laser as the LASIK procedure to reshape the outer layer of the cornea to correct nearsightedness, farsightedness, or astigmatism. Although LASIK is now more common, PRK is an alternative for patients who cannot undergo LASIK Surgery.

What can PRK do for me?

PRK can correct many of the same vision problems as LASIK, including:

  • Nearsightedness (myopia)
  • Farsightedness (hyperopia)
  • Astigmatism (irregularly shaped cornea)

PRK is also acceptable for individuals who are not eligible for LASIK for reasons such as:

  • Cornea too thin
  • Pupil too large

What happens during PRK surgery?

In preparation for surgery, anesthetic eye drops are administered. Next, a speculum is placed in the eye to keep the eyelids open. While the patient fixes his or her gaze on a target, the laser reshapes the cornea by removing tissue (a process called ablation), which is controlled and closely monitored by the doctor. The laser is actually guided by a detailed map of the patient's eye which has been programmed into a computer beforehand. The ablation usually takes around a minute for each eye, depending on the patient's vision prescription.

Is the procedure painful?

Most patients feel no pain during the procedure. After the procedure is complete, a bandage contact lens is placed on the eye. Most individuals may go home shortly after the procedure; however, someone else must drive or alternate transportation must be arranged.

How long is the recovery?

The doctor may prescribe pain medication to assist with recovery; however, most patients experience only minor discomfort. The doctor will also schedule several check-up appointments to monitor the healing process, followed by periodic visits over the next several months. During the recovery process, the patient should rest and refrain from any strenuous activities for at least a week. Most patients can return to work in a day or two, though it is best to take a few days off to ensure a smooth recovery.
