目的　对白内障超声乳化摘出及人工晶状体植入术中后囊膜破裂后处理进行分析。方法　在 2 2 8例老年性白内障、并发性白内障、先天性白内障者施行不同切口的超声乳化吸除 ,通过 3.2 mm切口植入折叠式人工晶状体 ,通过 5 .5 mm切口植入 PMMA人工晶状体。在术中后囊膜破裂 16眼 (6 .5 8% ) ,并发玻璃体外溢 6只眼 (2 .6 3% )。结果　术中人工晶状体植入的情况 :人工晶状体两袢均植入在囊袋内者有 9眼 ,其中人工晶状体一袢在睫状沟内的而另一袢在囊袋内的有 3眼 ,人工晶状体的两袢均植入在睫状沟的有 4眼。在随访平均 12 m o时 ,裸眼视力≥ 0 .5者有 13眼 ,占 81.2 % .裸眼视力≥ 1.0者有 8眼 ,占 5 0 % .与正常组对照无显著差异 (P>0 .0 5 )。结论　在白内障超声乳化吸除术中发生后囊膜破裂时 ,只要早期发现、沉着稳妥处理也能按预期植入后房型人工晶状体 ,且经随访观察无远期并发症 Objective To analyze the posterior capsular rupture after cataract phacoemulsification and intraocular lens implantation. Methods In 228 cases of senile cataract, complicated cataract and congenital cataract, different incision phacoemulsification was performed. The foldable intraocular lens was implanted through a 3.2 mm incision and the PMMA intraocular lens was implanted through a 5.5 mm incision. There were 16 eyes (6.78%) with rupture of the posterior capsule and 6 eyes (2.63%) with vitreous effusion. Results Intraoperative intraocular lens implantation: intraocular lens implantation in the capsular bag were 9 eyes, including intraocular lens in the ciliary sulcus and the other one in the capsule there are 3 eyes, Intraocular lens implantation are two in the ciliary sulcus 4 eyes. At 12 months of follow-up, there were 13 eyes (81.2%) with uncorrected visual acuity ≥0.5 and 8 eyes (≥50%) with uncorrected visual acuity ≥1.0 There was no significant difference between the two groups (P> 0.05) ). Conclusions When posterior capsular rupture occurs during cataract phacoemulsification, as long as early detection and stabilization of secundum implantation can be expected to implanted posterior chamber intraocular lens, and no long-term complications were observed after follow-up
