摘要

A consecutive series of 44 eyes of 22 patients who underwent radial keratotomy from Jan. 1987 to Dec. 1989 were studied. The range of follow-up was between 4 months and 39 months with a mean of 17 months. After radial keratotomy, 90.91% of eyes developed corneal iron deposition. The corneal iron deposition was significantly greater in eyes which pre-operative refractive error over -6.0D than in eyes which under -3.0D. And the mean change in corneal keratometry was significantly greater in eyes that developed prominent corneal iron deposition. The authors believe that alternations in corneal topography resulting from radial keratotomy lead to deposition of corneal iron.
