Abstract
Purpose. To report a new corneal iron ring after hyperopic laser-assisted i n situ keratomileusis (LASIK). Methods. Three patients underwent hyperopic LASIK for the correction of hyperopia in both eyes. Spherical equivalent re fraction of the patients ranged from +3.37 to +6.50 diopters. LASIK procedu re was performed using automated corneal shaper and 193-nm argon fluoride e xcimer laser. Results. Both eyes of the patients were noted to have a corne al iron ring located at the paracentral area at 6-7 months after surgery. T he localization of iron ring corresponded with outside border of central st eep zone. Twelve-month examination showed there was no change in color, sha pe, and density of corneal iron ring. Conclusions. Corneal topographic chan ges induced by hyperopic LASIK may cause corneal iron ring to develop.
