How is laser vision correctiondifferent from previous types of refractive eye surgery?
RK (radial keratotomy) is also a surgical procedure that can correct nearsightedness. With RK, the surgeon makes a series of cuts in the cornea; no laser is involved. You may know someone who has had RK, but it is rarely performed now and was never approved by the FDA. Current FDA-approved laser vision correction methods are PRK (photorefractive keratectomy) and LASIK (laser-assisted in situ keratomileusis).
