ABSTRACT
<p><b>INTRODUCTION</b>The aim of this study was to determine if racial differences exist in the rate of posterior capsule rupture (PCR) during cataract surgery in Singapore.</p><p><b>MATERIALS AND METHODS</b>All intraoperative complications during cataract surgery were prospectively reported as part of a clinical audit programme. A retrospective review of all patients who sustained a PCR during cataract surgery between July 1995 and December 1998 was performed.</p><p><b>RESULTS</b>Of 8230 consecutive eyes which underwent cataract surgery, 6951 (84.5%) were Chinese, 597 (7.3%) were Malay, 524 (6.4%) were Indian, and 158 (1.9%) were of other races. The overall incidence of PCR was 1.9%. The PCR rates were 1.8% [125 of 6951; 95% confidence interval (CI), 1.49 to 2.11] in Chinese, 2.0% (12 of 597; 95% CI, 1.01 to 3.57) in Malay, 2.7% (14 of 524; 95% CI, 1.13 to 3.56) in Indian, and 2.5% (4 of 158; 95% CI, 0.00 to 4.98) in other races. There was no statistical difference between the PCR rates (P = 0.62, chi-square test).</p><p><b>CONCLUSION</b>Racial differences in Singapore do not have an effect on the rates of PCR during cataract surgery.</p>
