What are the long-term results from LASIK?
While LASIK has only been in existence since 1991, another, very similar procedure called myopic keratomileusis (or MKM), has been performed for almost 40 years. LASIK is really a refinement of MKM, so there are 40 years of cases to draw on for conclusions. These cases tell us is that if patients are carefully selected for lamellar refractive surgery (like LASIK) then the long-term results are excellent.
