ABSTRACT
INTRODUCTION: 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. MATERIALS AND METHODS: 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. RESULTS: 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). CONCLUSION: Racial differences in Singapore do not have an effect on the rates of PCR during cataract surgery.

PURPOSE: To determine the short-term outcomes in eyes with posterior capsule rupture (PCR) during cataract surgery. SETTING: The Eye Institute, National Healthcare Group, Tan Tock Seng Hospital, Singapore, Singapore. METHODS: All intraoperative complications during cataract surgery were reported prospectively as part of a clinical audit program. The clinical charts of all patients who had PCR during cataract surgery from July 1995 to December 1998 were retrospectively reviewed. RESULTS: Posterior capsule rupture occurred in 155 (1.9%) of 8230 consecutive eyes that had extracapsular cataract extraction (ECCE) or phacoemulsification. Thirteen cases were excluded from analysis for missing data or insufficient follow-up. Of the remaining 142 eyes, 100 (70.4%) achieved a best corrected visual acuity (BCVA) of 6/12 or better between 6 weeks and 3 months postoperatively. Excluding 27 eyes with preexisting ocular pathology contributing to impaired vision, 87.0% achieved a BCVA of 6/12 or better. Fifteen eyes (13.0%) failed to achieve that acuity because of cystoid macular edema (CME) (2 eyes), posterior capsule opacification (2 eyes), endophthalmitis (1 eye), glaucoma (1 eye), retinal detachment (1 eye), CME, central retinal artery occlusion, and vitreous hemorrhage (1 eye) or unknown reasons (7 eyes). Risk factors for a poor visual outcome included older age, presence of coexisting ocular pathology, ECCE, implantation of an anterior chamber intraocular lens, and vitreous loss requiring anterior vitrectomy. CONCLUSIONS: Most eyes with PCR achieved a good BCVA in the early postoperative period.
