Wills eye hospital residents' intraocular lens experience.

Intraocular lens (IOL) operations performed by Wills Eye Hospital residents over a three-year period were reviewed retrospectively. The growing numbers of implants performed, the trends in methods of cataract extraction, the trends in types of intraocular lenses, and the relative safety of the procedure were examined. The estimate for the total number of intraocular lenses implanted by Wills Eye Hospital residents this past year was 600, or 60 per senior resident, and the percent of patients seeing 6/12 or better was 93.2%. There has been a great increase in the number of intraocular lenses implanted by residents at Wills Eye Hospital, with planned extracapsular cataract extractions and posterior chamber lenses currently favored. This analysis documents a very high visual success rate and acceptably low complication rate in closely supervised residents' surgery.
