Most eyes with PCR achieved a good BCVA in the early postoperative period.

There has been a significant increase in incidence of cases of Acanthamoeba keratitis presenting to our institution. The type of contact lens solution and the use of silicon hydrogel lenses combined with extended overnight wear may play a role; however, the significance is unclear given the small numbers for analysis. Further study of incidence and patient characteristics is warranted to identify risk factors and causes for the rising incidence.

Nanophthalmos is a rare ophthalmic condition with potential sight-threatening complications. In addition, nanophthalmic eyes have a high incidence of intraoperative and postoperative complications, including uveal effusion and retinal detachment. Prophylactic measures to prevent these complications may be used. The case is presented where cataract extraction for a nanophthalmic eye was performed from a posterior approach in combination with a pars plana vitrectomy and gas procedure. To the authors' knowledge, this method of cataract extraction has not been reported before for this condition.

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.
