A retrospective analysis of risk factors for posterior capsule rupture in cataract surgeries in a local center

Abstract

Aim: To analyze the risk factors for posterior capsule rupture in cataract surgeries.

Patients and methods: This retrospective study reviewed 269 eyes undergoing extracapsular cataract extraction and 235 eyes undergoing phacoemulsification at the Department of Ophthalmology, Caritas Medical Center.

Results: The rate of posterior capsule rupture for extra- capsular cataract extraction was 3.0%, while the rate for phacoemulsification was 7.7%. Chronic obstructive airway disease was a statistically significant risk factor for posterior capsule rupture in phacoemulsification. Hypertension, diabetes, bleeding disorder, types of anesthesia, theaters chosen for operations (implying different biomicroscopes used), preoperative sedation in patients having regional anesthesia, and surgical experience were not associated with the risk of posterior capsule rupture.

Conclusion: Preoperative improvement in the lung function of patients with chronic obstructive airway disease may reduce the risk of posterior capsule rupture in phacoemulsification.
