非对称性巩膜隧道切口人工晶状体植入术分析

An asymmetric scleral tunnel incision with implatation of intraocular lens

目的探讨在非对称性巩膜隧道切口下植入人工晶状体的效果。方法上方角膜缘后2mm为中心点作反“J”形巩膜隧道切口,圈出晶状体核后,植入后房型或前房型人工晶状体。结果本组10例(11只眼),外伤性白内障8只眼,先天性白内障3只眼,术后第1天平均视力0.1,术后第7天0.57,术后1个月0.6。术后并发症:角膜上皮轻度水肿7只眼,内皮线状混浊5只眼,无1例前房积血和角膜失代偿。结论非对称性巩膜隧道切口适用于外伤性白内障、先天性白内障摘除后小切口下植入较大光学直径的人工晶状体。

Objective To explore the effection using an asymmetric scleral tunnel incision with implatation of intraocular lens. Methods The whole nucleus by using a lens loop through an inverse J-shaped asymmetric scleral tunnel incision made 2mm from the limbus, then to perform implatation of posterior or anterior chamber IOLs. Results 11 eyes of 10 patients included 7 cases of traumatic cataract and 3 cases of congenital cataract. Their postoperative visual acnities were 0.1 at first day, 0.57 at one week and 0.6 at one month. Complications during operation included corneal edema （ 7 eyes） , linear opacity of corneal endothelium （5 eyes）. None of them was hyphema and corneal deoompensation. Conclusion An asymmetric scleral tunnel incision was suitable for implatation of large optic IOLs with small incision of traumatic and congenital cataract extraction.
