We reviewed the 2,095 cases among the 3,000 cases who underwent the intraocular lens(IOL) implantation from the first trial of IOL in 1978 to 30 th June, 1986. The data was analyzed by Minicomputer(Honewell Level 6 Model 57, U.S.A.) Cobal Language. The results were as follows; 1. Among the 2,095 cases, primary implantation was over 98%. The trend toward the posterior chamber lens(PCL) was increased annually. 2. The most commonly implanted intraocular lens power was +19.5D. in PCL and +18.0D. in ACL. Modified J loop type of PCL was used in 86% of PCL implantation. 3. The corrected visual acuity of 20/30 or better at postoperative 6 month follow-up was 78% in PCL group, and 70% in ACL group. 4. The mean spherical equivalent within +/-1.0D. at postoperative 6 month was 48% in cases were measured IOL power with biometry, and 37% in cases without biometry. 5. The average corneal endothelial cell loss at postoperative 6 month was 13.08 +/- 1.08% in PCL group, and 22.20 +/- 1.90% in ACL group. 6. The late postoperative complications were about 8%. There were pupillary abnormalities(21%), glaucoma(11%), after cataract(20%) and clinical cystoid macular edema(5%). 7. The preoperative mean corneal curvature(K-reading), axial length and IOL power was 42.9D., 23.9 mm and +18.4D., respectively.
