Canada's CityNews (5/21) reported that while laser-assisted in-situ keratomileusis (LASIK) can help correct vision, the surgery is "best suited for those with nearsightedness, farsightedness, or astigmatism." Approximately five percent of patients who undergo the procedure, however, experience complications, which include undercorrections, overcorrections, and astigmatism "caused by uneven tissue removal." In addition, some patients experience "glare, halos, and double vision," dry eyes, or "infection, tearing, and swelling." Individuals considering the procedure should find out how many LASIK procedures the surgeon has performed, the "surgeon's rate of retreatment," and the type of laser used. LASIK candidates should also consider if the price is "too good to be true." LASIK surgeon Dr. Sheldon Herzig, of the Herzig Eye Institute, cautioned bargain-hunting LASIK patients, saying, "You shouldn't discount... your vision. Your eyes are priceless, and you should only get the best."
