Posterior polar cataracts: A predisposition to intraoperative posterior capsular rupture

Abstract
We performed phacoemulsification or planned extracapsular cataract extraction on posterior polar cataracts in 31 eyes of 22 patients and experienced eight cases of posterior capsular rutpure (26%). Capsular rupture occurred during removal of the posterior polar opacity or during clensing of the posterior capsule after the opacity had been removed. We believe that excessive adherence of the opacity to the posterior capsule and unusual thinness of the capsule predisposed these eyes to posterior capsular rupture.
