Keratoplasty and intraocular lenses.

The art and science of intraocular lens implantation surgery is expanding. Highly successful results with elderly uncomplicated cataract patients have led to cautious implantation surgery in patients with co-existing eye disease. The results of implantation surgery achieved in sixteen patients with combined corneal disease and cataract formation are analyzed. In twelve patients penetrating keratoplasy was performed prior to cataract removal and implantation surgery, performed simultaneous with or in combination with secondary implantation in previously aphakic eyes. Vitrectomy was avoided in all primary lens insertion procedures but was necessary in two secondary implantations without ontoward effect. In this entire group of twelve patients all grafts have remained clear, there was minimal tissue reaction and visual return was excellent. In those with pre-existing corneal disease not requiring keratoplasty including one instance of Fuch's Corneal Dystrophy, there was no change in corneal status as a result of implantation surgery.
