PRK Eye Surgery Procedure

PRK Eye Surgery Procedure

 WHAT PRK EYE SURGERY IS?

PRK (Photo Refractive Keratectomy) laser eye surgery is similar to Custom Wavefront Optimized LASIK, as it involves using a laser to reshape the cornea. However, instead of forming a flap in the cornea to treat the deeper layers, the surgeon polishes a thin outer layer of the cornea.

 

HOW IT WORKS?

PRK treatment may be the best option for some eye conditions, and is often chosen if it is determined that the cornea is too thin to safely perform conventional LASIK surgery.

The outermost layer of your cornea (the epithelium) is first removed. An excimer laser is then utilized to reshape the curve of your cornea, which changes the way light travels through to the back of the eye. As a result, light entering the eye focuses more precisely on the retina. When this happens there is improvement in vision.

 

WHAT TO EXPECT?

The PRK laser eye surgery takes approximately 15 minutes. First anesthetic drops will be placed in your eyes.  The surgeon will then polish away the central area of the corneal epithelium in order to expose the part of the cornea that will be reshaped.  The excimer laser, which is programmed with your prescription, is used to reshape the underlying tissue of the cornea.

In order to protect your eye a soft contact lens will be placed on the cornea.

 

AFTER PRK EYE SURGERY?

For some patients PRK laser eye treatment is more advantageous than conventional LASIK surgery, despite it having a longer recovery period and more discomfort. The soft contact lens bandage is removed in approximately 5 days after surgery. Improvements in vision may be experienced more gradually, ranging from a few days up to 2 weeks. The majority of patients are able to drive approximately 1 to 3 weeks after the surgery. It may take 3 to 6 months to notice ideal vision. Learn more about PRK EYE SURGERY
