PURPOSE: Posterior capsule rupture is defined as an intraoperative posterior capsule tear resulting in vitreous loss. This study aimed to analyze the clinical characteristics, preoperative risk factors, intraoperative management strategies, and postoperative complications associated with posterior capsule rupture during phacoemulsification surgery.
METHODS: This was a retrospective observational cohort study of the medical records for 25,224 phacoemulsification surgeries performed at our tertiary eye care center between 2017 and 2022. We collected and collated the demographic characteristics and clinical findings of the patients in our cohort. Intraoperative management strategies and postoperative outcomes over a 1-year followup period were also recorded.
RESULTS: Posterior capsule rupture occurred in 351 eyes (351 patients), giving an overall posterior capsule rupture rate of 1.3%. The mean patient age was 68.6 ± 10.8 years. Pseudoexfoliation syndrome, mature cataracts, brown cataracts, and surgery performed by a resident were identified as risk factors for posterior capsule rupture (p<0.05 for each; the risk ratios were 2.70, 2.15, 2.44, 1.34, respectively). The most common intraoperative complications were dislocated lens fragments in the vitreous (8%) and iris damage (7.1%). The mean best-corrected visual acuity improved from 1.31 ± 0.84 (logMAR) postoperatively to 0.51 ± 0.56 at the end of the 1-year follow-up period (p<0.001). Corneal edema (55.6%) and elevated intraocular pressure (33.3%) were the most common early postoperative complications. Persistently elevated intraocular pressure (11.1%) and cystoid macular edema (5.1%) were the most common late postoperative complications.
CONCLUSION: Posterior capsule rupture is a common complication of phacoemulsification surgery that requires prolonged postoperative follow-up and a multidisciplinary approach. Despite the increased incidence of complications when rupture occurs, appropriate intraoperative and postoperative management can lead to satisfactory visual outcomes.
