Keratoplasty with primary and secondary lens implantation.

Twenty-eight patients who had cataract and corneal scarring were operated on with combined penetrating graft, cataract extraction, and lens implantation (group A); 20 patients who had aphakic corneal dystrophy or dystrophy caused by intraocular lens received simultaneous penetrating graft, vitrectomy, and lens implantation or revision of the intraocular lens (group B). Group B had more severe disorders and more complicated surgery, and therefore poorer visual results than group A.
