PRK, short for photo refractive keratectomy, is a procedure which utilizes the excimer laser to reshape your cornea. This procedure can correct nearsightedness or farsightedness, as well as astigmatism associated with nearsightedness.

To correct nearsightedness, the excimer laser beam is directed on the central surface of the cornea. The pulses of ultraviolet light remove microscpic layers of the cornea. This flattens the cornea so the light rays are focused on the retina.

To correct farsightedness, the excimer laser beam is directed on the peripheral surface of the cornea. The pulses of ultraviolet light remove microscopic layers of the cornea and reshapes the cornea to compensate for too little curvature.

The Procedure-What to expect?

Prior to the procedure, your eye is numbed with drops so you are comfortable. During the procedure you will lie flat on a chair and will be awake. Your eyelids are held open with a special instrument and you will be asked to look at a small light. The laser treatment usually takes less than one minute.

Risks and Side Effects of PRK

As with any surgical procedure, risks are involved. Prior to PRK, risks and side effects will be explained in detail and you will be asked to sign a consent form.

Infection, although rare, could scar your cornea and decrease your vision. Irregular asigmatism, over correction or under correction are possible. Some people become more sensitive to glare or see halos around lights. A haze may develop in the cornea and vision may remain cloudy for a period of time.
