摘　　要：目的 评价小切口白内障摘除术术中后囊膜破裂的原因及处理方法。方法 回顾分析1056例小切口白内障手术联合人工晶体植入术,其中术中51例后囊膜破裂,玻璃体溢出,行前段玻璃体切割术联合一期后房型人工晶体植入术。结果 本组患者手术中后囊膜破裂发生率为4.8%,全部行一期后房型人工晶体植入术,其中5例囊袋内固定植入,42例睫状沟固定植入和4例DGR人工晶体双襻缝线固定法植入。术后矫正视力大于或等于0.3者46例(90.2%); 矫正视力大于或等于0.05,低于0.3者4例(7.8%);矫正视力低于0.05者1例(2.0%)。结论 前段玻璃体切割术为小切口白内障摘除术中后囊膜破裂一期人工晶体植入提供了安全有效的保证。Objective To analyze the causes of posterior capsulorhexis in small incisioncataract surgery with intraocular lens implantation and deal with methods.Methods The authorsperformed a retrospective study that 51 cases of posterior capsulorhexis caused vitreous loss from 1056patients, which were performed phacoemulsification or small incision cataract surgery with intraocularlens implantation, were given anterior vitrectomy combined with primary posterior chamber intraocularlens implantation.Results The rate of posterior capsulorhexis was 4.8%.All of the cases withposterior capsulorhexis were performed on primary posterior chamber intraocular lens implantation.In-the-bag intraocular lens implantation was performed on 5 cases,the sulcus-fixed intraocular lensimplantation on 42 cases,and Dgr loop-fixed intraocular lens implantation on 4 cases. After follow upfor 1～15 months (mean 6.6 months),46 cases had the best corrected visual acuity (BCVA)≥0.3(90.2%),4 cases had BCVA of 0.05 or lower 0.3(7.8%),and 1 case had BCVA < 0.05(2.0%). Conclusions Anteriorvitrectomy furnished benificial condition to primary posterior chamber intraocular lens implantationin eyes with vitreous loss due to posterior capsulorhexis after small incision cataract surgery withintraocular lens implantation.
