晶状体玻璃体切割术后透明角膜切口的二期人工晶状体植入术

目的 探讨晶状体玻璃体切割术后经颞侧透明角膜隧道切口的二期折叠式人工晶状体植入术的手术方法和疗效.方法 通过颞侧透明角膜隧道切口对晶状体玻璃体切割术后6～12个月的29例（29眼）二期植入折叠式人工晶状体,用聚丙烯缝线将人工晶状体襻固定于睫状沟中.术后随访6～18个月,观察术后视力、人工晶状体位置及术中术后并发症.结果 术后3个月裸眼视力＞0.5者16眼,0.3～0.5者12眼,0.2～0.3者1眼.术后视力与术前最佳校正视力相比较,差异无统计学意义（P＞0.05）.手术并发症主要为眼内出血（1眼）、人工晶状体倾斜（2眼）.结论 经颞侧透明角膜隧道切口及睫状沟缝合固定襻的折叠式人工晶状体植入术,手术效果可靠,并发症少,是晶状体玻璃体切割术后无晶状体眼屈光矫正的理想手术方式.

Secondary intraocular lens implantation through tunnel incision on temporal clear cornea after lensectomy and vitrectomy

Objective To investigate the methods and effect of secondary intraocular lens (IOL)implantation through tunnel incision on the temporal clear cornea after lensectomy and vitrectomy.Methods 29 cases were implanted with secondary foldable IOL through tunnel incision on the temporal clear cornea after 6~12 months of traumatic lensectomy and vitrectomy,and IOL was fixed with polypropylene suture fixation at ciliary sulcus.Post-operative vision,IOL position,intraoperative and post-operative complications were observed for 6~18 months after the operation.Results Three months after surgery,the visual acuity were >0.5 in 16 eyes,0.3~0.5 in 12 eyes and 0.2~0.3 in 1 eye.There was no statistically significant difference between post and pre-operative corrected visual acuity (P>0.05).The common complications were hemalopia(1 eye) and the IOL displacement(2 eyes).Conclusion Through tunnel incision on the temporal clear cornea,secondary foldable IOL implantation with polypropylene suture fixation at ciliary sulcus is successful to correct ametropia in aphakic eyes after traumatic lensectomy and vitrectomy.
