Corneal iron ring after hyperopic photorefractive keratectomy.
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.
