AIM:To study the causes and management of posterior capsule rupture(PCR) in manual small incision cataract surgery(MSICS). METHODS:The clinical datas of 360 eyes undergoing MSICS in our hospital from 2008 to 2010 year was reviewed,and the causes and management of PCR in 26 eyes were analysed. RESULTS:These 26 eyes all got intraocular lens implantation, and the number of eyes which achieved a best-corrected visual acuity of 0.3 or more was 22(84.6%).No serious complications occurred. CONCLUSION:Posterior capsule rupture which occurrs in diferent stages of the operation was the commonest intraoperative complication in MSICS. The incidence of PCR can be decreased by careful operation,and suitable management leads to satisfactory outcome.
