Photorefractive Keratectomy (PRK) consists of using an excimer laser to ablate a thin amount of tissue from the cornea's surface. Most focusing problems can be compensated for by this slight adjustment to the shape of the cornea. Myopia, astigmatism, and myopia with astigmatism can be treated with PRK laser vision correction.

Radial Keratotomy (RK) is one of the oldest refractive surgery procedures. RK involves making incisions in a radial pattern on the surface of the cornea. These incisions cause the surface of the cornea to flatten slightly, which can achieve the desired result – correcting nearsightedness. Unfortunately, the results were unpredictable and unstable. The more accurate laser vision correction procedures available today are generally preferable to RK.
- Astigmatic Keratotomy (AK) is somewhat similar to radial keratotomy, the difference being that astigmatic keratotomy is performed to treat astigmatism. Incisions are made to flatten specific areas of the cornea. If executed correctly, AK can treat astigmatism. However, like RK, the AK procedure is somewhat unreliable and has been supplanted by modern laser vision correction techniques.
