PURPOSE: To evaluate the association between intraoperative complications of cataract surgery and postoperative mortality. METHODS: A retrospective review of patients who underwent cataract surgery at our institution from 2014 to 2020 was conducted. Intraoperative complications included choroidal hemorrhage, posterior capsule rupture, vitreous loss, retained lens, and/or severe zonular dialysis in either eye. All-cause mortality statistics were obtained through a collaborative agreement with the Colorado Department of Public Health and Environment. Hazard ratios (HRs) from Cox proportional hazard models were used to estimate survival following cataract surgery. RESULTS: Among 8,054 patients, the mean follow-up time was 4.4 (SD = 2.3) years and the mortality rate was 15% ( CONCLUSION: Intraoperative cataract surgery complications were associated with mortality in univariate analysis. However, this association was not significant in the multivariable analysis as it is confounded by other factors such as pre-operative visual acuity.
