Photorefractive Keratectomy (PRK)
Photorefractive Keratectomy, more commonly called PRK, is a laser vision correction procedure. PRK is often a good solution for people with thinner than normal corneas—but your surgeon will be able to determine which procedure is best for your individual needs.

Nearsightedness
Myopia, also known as nearsightedness, is a common type of refractive error where close objects appear clearly, but distant objects appear blurry.
-
Astigmatism
Astigmatism causes your vision to be blurred at both near and far distances. It occurs when your cornea is shaped more like a football than a basketball.
-
Farsightedness
Hyperopia, also known as farsightedness, affects nearly one in four people. Those with hyperopia can see distant objects very well but have difficulty focusing on objects that are close.

Is PRK right for me?
PRK is often a good solution for people with certain corneal issues, such as thin corneas, and provides visual results very similar to LASIK and SMILE. Your NVISION surgeon will determine which laser vision correction is right for your individual needs based on your eye exam and your visual goals.

What is PRK?
PRK (“photo-refractive keratectomy”) was the first vision correction procedure to use excimer lasers and specifically involves reshaping the surface cornea rather than the inner corneal tissue as with LASIK. PRK also differs from LASIK in that no corneal flap is required.

What conditions does PRK treat?
Just as with LASIK, PRK is a procedure to help people with nearsightedness, farsightedness, and astigmatism. But every patient is different, and your NVISION surgeon will select the best procedure for your needs.

NVISION® Eye Centers can be found throughout California, Nevada, Oregon, and in Toronto, Canada. Each center is a little bit different—but what they have in common are talented NVISION® surgeons, caring staff, and a commitment to a gold standard for patient care.
