title: [Reason and management of posterior capsular breaks during cataract extraction and lens implantation].
abstract: OBJECTIVE
  To study the reason and management of posterior capsular bresks during cataract extraction and lens implantation.
  
  
  METHODS
  The authors analyse the reasons of posterior capsular brseaks during cataract extraction and lens implantation on 55 eyes and discuss the management according to the different situations.
  
  
  RESULTS
  The posterior capsular disruption occurred most frequently during cortical cleanup on 21 eyes (38.2%) and lens implantation on 21 eyes (38.2%). The diameter of the tears was about 3 mm on 39 eyes (70.9%), about 5 mm on 13 eyes (23.6%) and larger than 6 mm on 3 eyes (5.5%). The tears with central defined borders were on 12 eyes (21.8%), with peripheral defined border in one side on 39 eyes (71%), with pooly defined borders on 3 eyes (5.5%). Final visual acuity of 0.5 or better was achieved on 35 eyes (63.6%).
  
  
  CONCLUSIONS
  When the complication occurs during the operation, we should use the suitable management according to the different situations in order to reduce the loss of the complication.
