Abstract
- One hundred and twenty-three cases of planned ECCE with biconvex posterior chamber lens implantation were performed in St. Mary's Hospital from April 1988 to February 1990, were followed up for more than 6 months. We also analyzed 123 cases of planned ECCE with convex-plano posterior chamber lens implantation during the same period. The results were as follows: 1. The difference of visual acuity between the two groups was not statistically significant. 2. Of the 123 eyes with biconvex lens, 106 eyes (86%) were within +/- 0.50 spherical equivalent diopter compared to 55 of 123 eyes (44.7%) with convex-plano lens. This difference is statistically signficant (p<.001). 3. Eight out of the 123 eyes with biconvex lens (6.5%) developed after-cataract and two of these eight eyes were of the central type: 36 out of the 123 eyes (29.3%) with convex-plano lens developed after-cataract and 31 of the these 36 eyes were of the central type. This difference is statistically significant(p<.001).
