PRK refers to Photorefractive Keratectomy.
Surface Laser Ablation was the first type of laser eye surgery for vision correction.
With PRK the recovery time is longer than that of LASIK or SMILE® Pro.
However, it is still widely performed and offers several advantages over some other treatment options for some patients.
PRK is safe, efficient, and predictable
Gently removes corneal tissue without creating a flap of corneal tissue
PRK uses a state-of-the-art laser beam to alter the top layer of corneal cells
Suitable for thinner and irregular shaped cornea
May be possible for patients with mild dry eye symptoms
Visual outcome of PRK is excellent
A diluted alcohol solution is applied to the cornea to dissolve the epithelial layer.
The epithelial layer is then removed or moved to the side using a manual instrument.
The Excimer laser sculpts the corneal tissue within a matter of seconds to correct the visual defect.
Finally, a protective bandage lens is placed over the eye until the epithelium grows back within a few days.
