“Laser-assisted in situ keratomileusis” (LASIK) is a routine surgery to correct near- and farsightedness as well as astigmatism. It’s a preferred treatment (in fact, it’s one of the most common laser eye surgeries) for a reason: it’s virtually pain-free and takes minutes. Moreover, improved results can be literally seen within a day. Pronouncing its unabbreviated name, however, isn’t LASIK’s greatest challenge. This procedure isn’t for everyone. Unfortunately, there are limitations as to who will qualify as a good candidate.
