In brief: Relatively common
Prk is second only to lasik as the most common corneal treatment for nearsightedness, farsightedness and astigmatism.
Both procedures use a laser to reshape the cornea. In lasik, a flap is first made and the laser is applied under it, while in prk laser is applied directly to the front of the cornea after removing the surface skin. Lasik is more comfortable and one heals more quickly from it.

In brief: Less than LASIK
Prk was very common at one time, because a flap in the cornea was not required.
Now with custom ablations, lasik, lasek and other types of refractive surgeries, it is used less commonly. It still has a place in patients with certain types of corneal disorders where a flap might cause a problem with healing, or if the ocular surface would benefit from the prk. Please discuss with your eyemd.
