Abstract

The implantation of intraocular lens(IOL) has now been routinely used in cataract surgery and its indication has more extended gradually. Improvement of surgical methods, IOL designs and dvelopment of viscoelastic substance have accelerated the implantation of IOLs. In Korea, 20 IOL Study Club also was organized in 1984. And in 1988, domestic mode IOL named UNI-PCL was finally approved from ROK government. This report is concernd to investigate the datas of IOL implantations in Korea by use of questionnaire method which was conducted by prof. Dr. Jae Ho Kim. The brief summary on 21,779 IOL cases from 1975 to May 31, 1988 is as follows. 1. Cases of Primary IOL implantation were 21,093(973%) among 21,779 cases and posterior chamber lens(PCL) implantation was done in 20,242 case(95%) among primary IOL implantation. 588 cases(2.7%) were secondary IOL implantation, among them, cases of ACL implantation were 361(61.4%). 2, PCL implantation was done in 20,269 cases(91.1%) and ACL implantation in 1,412 cases(6.4%). It shows that PCL implantation has increased in number annually. 3. J-loop type of PCL including modified J-loop type was most comonly used and the use of C-Ioop type was gradually increased. 4. Posterior capsule rupture was the most common complication in intraoperative period, However, the transient intraocular pressure rise and after cataract were the most common complications in early and late postoperative period. 5. The most common cause of blindness after IOL implantation was bullous keatopathy. 6. In this study, number of surgeons who performed IOL implantation were 120 and IOL implantation was thought to be performed more than 75 hospitals including general hospital and offices.
