Cleaner LASIK is possible.

LASIK (laser in situ keratomileusis) surgery is the most frequently performed refractive procedure for correcting nearsightedness, farsightedness, and astigmatism. Its popularity increased over the late 1990's, rapidly replacing Radial Keratotomy (RK). The LASIK operation and excimer laser surface ablation procedures gained the rapid acceptance of refractive physicians and patients over the RK procedure because of greater predictability, precision, safety, and stable vision.
