Our 20/20 LASIK Blog

PRK is the original laser vision correction procedure, invented during the 1980s. For some people, PRK still offers advantages over other laser vision correction options.

In PRK, the WaveLight Allegretto Wave Eye-Q excimer laser is used to reshape the cornea so that light focuses properly on the retina. For a more detailed explanation, see our How the Eye Works page. This makes PRK similar to LASIK and other forms of laser vision correction.

What makes PRK different from LASIK is this: in PRK, the laser reshapes the surface of the cornea, but in LASIK a flap is created so that the laser can be used to reshape the middle of the cornea.

For some people, PRK is a better option than LASIK. If you have been told you cannot have LASIK either because you have thin corneas or because your pupils are too large you may be an ideal candidate for PRK.
