Critical Analysis of Posterior Capsule Rupture
Purpose
Three retrospective studies of rupture of the posterior capsule in different periods of time will be presented and a critical analysis of its causes will be discussed.
Methods
The first retrospective study of 7356 cataract surgery cases between 1998 and 2006; the second study of 1418 cases in 2007 and the third study of 6514 cases between 2012 and 2014. All retrospective studies of patients that underwent cataract surgery of phacoemulsification at our institution Clínica Oftalmológica del Caribe that had complete clinical record and film support.
Results
In the first retrospective study we found 319 cases of posterior capsular rupture (4.34%); in the second study we found 30 cases (2.11%) and in the third study we found 96 cases (1.47%). We present a demographic analysis and also the critical analysis of the different moments in which a posterior capsular rupture can present.
Conclusion
The posterior capsular rupture is the most frequent complication in cataract surgery. The great majority of cases occurred during the emulsification of the nucleus. It is a complication that with the adequate analyses and follow-up can somehow be prevented. The use of the polymer tip for the I/A contributes to decrease the ruptures in this step of the surgery.
