title: Corneal iron ring after hyperopic photorefractive keratectomy.
abstract: OBJECTIVE
  To report the incidence and course of corneal iron deposition after hyperopic photorefractive keratectomy (PRK).
  
  
  METHODS
  Gazi University, Medical School, Department of Ophthalmology, Ankara, Turkey.
  
  
  METHODS
  Between January 1995 and December 1997, 62 eyes had PRK to correct hyperopia.
  
  
  RESULTS
  Nine eyes developed corneal iron ring 5 to 8 months (mean 6.25 months +/- 1.3 [SD]) after PRK for hyperopia. The rings persisted during the mean follow-up of 19 +/- 11.09 months.
  
  
  CONCLUSIONS
  The ring-shaped iron deposition after PRK for hyperopia must be differentiated from the Fleischer ring. Our results suggest that the slitlamp findings of peripheral corneal iron deposition in hyperopic PRK patients correlate with achieved correction.
