AIM:To analyze the cause of posterior capsular rupture in small incision non-phacoemulsification cataract surgery and investigate the treatment methods.

METHODS: The clinical data of 108 cases(121 eyes)undergone small incision non-phacoemulsification cataract surgery combined with intraocular lenses(IOL)implantation were retrospectively analyzed. The causes of posterior capsular rupture and treatment of 6 patients(6 eyes)after surgery were analyzed and summarized.

RESULTS: Six cases(6 eyes, 4.96%)occurred posterior capsular rupture during the operation, of which 2 cases(2 eyes)underwent posterior chamber IOL implantation intraoperative, 2 cases(2 eyes)received Ⅱ stage IOL implantation in the ciliary sulcus at 1wk postoperative, 2 cases(2 eyes)were given anterior chamber IOL implantation. One case(1 eye)whose vision acuity <0.1 was macular degeneration; One case(1 eye )whose vision acuity=0.3 was diabetic retinopathy; 0.4～0.6 in 2 cases(2 eyes), 0.6～0.8 in 2 cases(2 eyes)after 1～3mo postoperatively. No severe syndrome was found after surgery.

CONCLUSION: Posterior capsular rupture which occurs in different stages of the operation is the commonest intraoperative complication in small lincision non-phacoemulsification cataract surgery. With improving operative techniques, and continuously accumulating experience, incidence of posterior capsular rupture can be effectively reduced. Even posterior capsular rupture occurs intraoperative, patients can still get a good outcome after timely and proper treatment.
