Purpose: To determine the prevalence and types of intraoperative complications of cataract surgery and examine potential risk factors.

Methods: Data were obtained from the 2011 Iranian Cataract Surgery Survey in which information about cataract surgeries throughout the nation was collected. In the Province of Tehran, 55 centers and 1 week per season per center were randomly selected for sampling. In each center, the charts of all patients who underwent cataract surgery during the selected weeks (total of 20 weeks per center) were reviewed for data extraction. The prevalence of different types of intraoperative cataract surgery complications were determined, and their relationships with age, sex, surgical method, surgeon, and hospitalization time were examined.

Results: The prevalence of intraoperative complications of cataract surgery was 4.15% (95% confidence interval, 0.94 to 7.36). The prevalence of posterior capsular rupture with vitreous loss, posterior capsular rupture without vitreous loss, retrobulbar hemorrhage, suprachoroidal effusion/hemorrhage, intraocular lens drop, and nucleus drop was 2.86, 0.69, 0.06, 0.39, 0.03, and 0.11%, respectively. The prevalence of cataract surgery complications decreased from 6.95% in 2006 to 3.07% in 2010. The results of multiple logistic regression showed that surgery by residents, nonphacoemulsification methods of surgery, and patient age less than 10 years and more than 70 years were the risk factors for complications.

Conclusions: This study evaluated the prevalence of intraoperative complications of cataract surgery for the first time in Tehran Province. The prevalence of complications was high in this study. To achieve the goals of the Vision 2020 Initiative and improve surgical quality, it is necessary to minimize complication rates. Factors to note for decreasing complication rates include type of surgery, surgeon experience, and patient age.
