Corneal iron ring after hyperopic photorefractive keratectomy.

PURPOSE: To report the incidence and course of corneal iron deposition after hyperopic photorefractive keratectomy (PRK).

SETTING

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.

CONCLUSION

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.
