So, I was going to get lasic, but my eyes are too thin so they suggested getting PRK. They explained it's a little more painful and takes a little longer to get the final results, but is just as good. Has anyone else every had PRK? What should I expect?

PRK: The Original Laser
Eye SurgeryBy Liz Segre; reviewed by Charles Slonim, MD
PRK (photorefractive keratectomy) once was the most common refractive surgery procedure before LASIK was developed as a more popular alternative.
Both PRK and LASIK are grouped under the umbrella "laser eye surgery," but each is a little different when it comes to advantages and disadvantages.
LASIK patients have less discomfort and obtain good vision more quickly — whereas, improvement with PRK is gradual and takes days, weeks or even months. But many surgeons prefer PRK in circumstances such as when patients have thin corneas.
PRK was invented in the early 1980s. The first FDA approval of a laser for PRK was in 1995, but the procedure was practiced in other countries for years. In fact, many Americans had the surgery done in Canada before it was available in the United States.
PRK is performed with an excimer laser, which uses a cool ultraviolet light beam to precisely remove ("ablate") very tiny bits of tissue from the surface of the cornea in order to reshape it. When you reshape the cornea in the right way, it more precisely focuses light into the eye and onto the retina, providing clearer vision than before.
Both nearsighted and farsighted people can benefit from PRK. With nearsighted people, the goal is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. Also, excimer lasers can correct astigmatism, by smoothing an irregular cornea into a more normal shape.
