PURPOSE: To report a new corneal iron ring after hyperopic laser-assisted in situ keratomileusis (LASIK).
METHODS: Three patients underwent hyperopic LASIK for the correction of hyperopia in both eyes. Spherical equivalent refraction of the patients ranged from +3.37 to +6.50 diopters. LASIK procedure was performed using automated corneal shaper and 193-nm argon fluoride excimer laser.
RESULTS: Both eyes of the patients were noted to have a corneal iron ring located at the paracentral area at 6-7 months after surgery. The localization of iron ring corresponded with outside border of central steep zone. Twelve-month examination showed there was no change in color, shape, and density of corneal iron ring.
CONCLUSIONS: Corneal topographic changes induced by hyperopic LASIK may cause corneal iron ring to develop.
