Abstract

Corneal transplantation of three hundred and twenty five cases operated at the Department of Ophthalmology, Kangnam St. Mary's Hospital, Catholic University Medical College from May 1980 to December 1987 were clinically evaluated. The follow up period ranged from 1 month to 6 years(mean: 3 3/4 years). Major causes of corneal opacity were keratitis(105 eyes, 32.3%) and trauma(50 eyes, 15.4%), followed by keratoconus(50 eyes, 15.4%) and bullous keratopathy(46 eyes, 14.2%). There were 233 eyes of partial penetrating keratoplasty, 59 eyes of lamellar keratoplasty, 4 eyes of keratoplasty with IOL implantation and 29 eyes of prostho-keratoplasty. Success rate was 74.3% by maintaining clarity among 220 eyes out of 296 eyes except of cases of prostho-keratoplasty. Among the 76 eyes with graft opacity, 35 eyes were caused by graft rejection and 19 eyes, by bullous keratopathy. Among the cases of keratoplasty, 112 eyes showed postoperative bestcorrected visual acuity of 0.5 or higher(35.2%), 134 eyes were between 0.1 and 0.4(42.1%), and 246 eyes were 0.1 or higher(77.3%). Corneal endothelial cell density change from before the corneal transplantation was 42.3% decrease at 1 year post-operatively and 18.4% decrease at 3 months postoperatively.
