title: Corneal iron ring after hyperopic laser-assisted in situ keratomileusis.
abstract: OBJECTIVE
  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.
