Secondary lens implantation in aphakia: visual results and complications.

We reviewed 70 cases that had undergone secondary lens implantation. The lenses used included 34 Medallion and 36 Choyce Mark VIII lenses. A 20/40 or better vision was present in 74.3% of the cases before implantation, and could be achieved postoperatively in 95.7% of the cases. Corneal changes, i.e. endothelial corneal dystrophy and induced astigmatism, were not noted in cases where Choyce Mark VIII lenses were used. Cystoid macular edema occurred in three cases where surgery followed an intracapsular cataract extraction (5.3%).
