LASEK (or laser-assisted subepithelial keratomileusis) is a laser vision correction procedure that is similar to both LASIK and PRK. Like LASIK, LASEK can also be used to treat farsightedness, nearsightedness or astigmatism. It is also a type of laser presbyopia surgery when it is used for the treatment of age-related nearsightedness.
