白内障术中后囊破裂的Ⅰ期后房型人工晶状体植入术

目的评价白内障囊外摘出术中后囊破裂行前段玻璃体切割联合Ⅰ期后房型人工晶状体植入的手术效果。方法对１４８０例白内障囊外摘出联合后房型人工晶状体植入术中４９例后囊破裂，行前段玻璃体切割联合Ⅰ期后房型人工晶状体植入的手术技巧、术后并发症和术后视力等进行分析。结果手术后囊破裂率为３．３％，７０％患者人工晶状体植入囊袋内，３０％患者为睫状沟，８９．９％患者出院时裸眼视力≥０．５。结论白内障囊外摘出术中后囊破裂，行前段玻璃体切割联合Ⅰ期后房型人工晶状体植入是安全有效的。

Primary posterior chamber intraocular lenses in eyes with posterior capsulorhexis following extracapsulor cataract extraction

Objective To evaluate the effect of anterior vitrectomy combined with primary implantation of posterior chamber intraocular lens for the posterior capsulorhexis following extracapsular cataract extraction.]Methods Anterior vitrectomy combined with primary implantation of posterior chamber intraocular lens was performed on 49 cases from 1 480 cases of posterior capsulorhexis following extracapsular cataract extraction.The surgical technique,postoperative complication and postoperative visual acuity were analyzed. Results In 49 cases,70% of the intraocular lenses were implanted in capsular bag,the rest were in ciliary sulcus.The visual acuity was 0.5 or better in 45 cases postoperatively.The rate of posterior capsulorhexis was 3.3%.THZ]Conclusions Anterior vitrectomy combined with primary implantation of intraocular lens for posterior capsuloxheris following extracapsular cataract extraction is safe and effective.
