PRK (photorefractive keratectomy) 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 for nearsightedness, farsightedness, and astigmatism.  These days LASIK is more common, but PRK is still an alternative for patients who cannot undergo LASIK Surgery.

Reasons to consider PRK:

• Nearsightedness  (myopia).
• Farsightedness (hyperopia.
• Astigmatism (irregularly shaped cornea).
• Cornea too thin for LASIK.
• Pupil too large for LASIK.

The Procedure

In preparation for surgery, anesthetic eye drops will be administered.  Next, a speculum is placed in the eye to keep the eyelids open, which is normally not uncomfortable.

PRK involves the removal of a small portion of the upper surface level of the cornea called the epithelium.  There are no needles or blades involved.  The inner cornea is then exposed  in order for  the computer-assisted laser to begin its reshaping  by removing tissue (a process called ablation).  This step of the procedure usually takes around a minute for each eye, depending on the patient’s vision prescription.   The entire process is controlled and closely monitored by the doctor while the laser, called the excimer laser, is being guided by a detailed map of the patient’s eye which has been programmed into a computer beforehand. 

After the procedure is complete, a bandage contact lens is placed on the eye, which will be removed within 2-5 days.  The patient may go home shortly after the procedure; however, someone else must drive or alternate transportation must be arranged.

The Recovery

The doctor may prescribe pain medication for use 1-2 days postoperatively. 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 3-4 days, depending on the healing process.
