We reviewed 44 eyes of pseudophakic(PC-IOL)retinal detackment in which 12 eyes had their posterior lenticular capsules broken,7 of them during the operation and 5 after postoperative YAG laser eapsulotomy.Eleven of the 12 eyes (91.7%) had their retinal detached within 1 year after cataract extraction associated with Intraocular lens implantation,and 18 eyes in 32 eyes(56.3%) with intact po6terior lenticular capsules had their retinae detached within 1 year.The difference between the above conditions was statistically significant (Plt;0.05), Thirty-six of 44 eyes(81.8%) had their detached retinae reattaehed after surgical treatmint. And we found that advanced proliferative vitroretinopethy and failure of detection of retinal breaks played important role for failure of surgical treatment in this series. （Chin J Ocul Fundus Dis,1994,10:74-76）
