Abstract

To get the pure clinical results of Yag Laser Posterior Capsulotomy, excluding all the possible factors that might affect the results of that, we performed posterior capsulotomies on after cataracts(118 eyes) by using Q-switched Nd:Yag laser from February 1987 to August 1989 and reviewed the results. Group A is composed of 68 surgical aphakic eyes and group B is composed of 50 Posterior chamber pseudophakic eyes. The results were as follows: 1. One eye in groupA and one eye in group B were congenital cataracts and the others were all adult and senile cataracts. 2. As a result of posterior capsulotomy, 59 eyes(86.8%) in group A and 42(84%) in group B were above 0.5 in corrected visual acuity. 3. On performing, the power setting was under 1.5mJ in 59 eyes(86.8%) in groupA and 40 eyes(80%) in group B. 4. Ocular complications developed in 35 eyes(51.5%) in group A and 15 eyes(30%) in group B. 5. Good preoperative ocular condition may predict good postoperative clinical results. 6. Less energy and pulses in operation combined with less occurrences of vitrous prolapse in group B might be associated with less development of postoperative complications in group B than in group A.
