Thirty-three keratophakias were performed at Holy Cross Hospital in Mission Hills, California between August 1979 and October 1982. Nineteen were primary, combined with cataract surgery; 14 were secondary, performed on aphakic eyes. Data on the 23 cases that had a minimum follow-up time of one year were analyzed by an independent observer. Best visual acuity obtained at seven months was 20/40 or better in 62% of the patients. Induced keratometric astigmatism averaged 1.0 diopter and manifest refractive astigmatism 2.0 diopters. The results of secondary keratophakia vs keratophakia combined with cataract extraction were compared. Accuracy, complication rate and final visual recovery suggest that the combined procedure is safe and effective, and that primary keratophakia does not add a significant risk to cataract surgery.
1979年8月至1982年10月期间，在加利福尼亚州米申山的圣十字医院进行了33例角膜移植术。19例为原发性，与白内障手术联合进行；14例为继发性，在无晶状体眼上进行。由一名独立观察者分析了23例至少随访一年的病例数据。7个月时获得的最佳视力在62%的患者中为20/40或更好。诱导性角膜散光平均为1.0屈光度，显性屈光散光为2.0屈光度。比较了继发性角膜移植术与角膜移植术联合白内障摘除术的结果。准确性、并发症发生率和最终视力恢复情况表明，联合手术安全有效，原发性角膜移植术不会给白内障手术增加显著风险。
