摘要
探讨经颞侧透明角膜隧道切口的二期人工晶体植入术的方法及优点。方法 :用钻石刀在颞侧角膜周边血管弓中央的透明角膜上 ,做一深 0 3mm ,长 3 2mm ,宽 1 75mm的角膜隧道切口 ,对 5 0例5 3只眼的无晶体眼行二期人工晶体植入术 ,植入可折叠人工晶体。随访 6～ 12个月 ,平均 8 4个月 ,观察术后视力、角膜曲率、人工晶体位置及术中、术后并发症。结果 :手术时间为 15～ 40分钟 ,平均 2 6分钟。术后第一天矫正视力≥ 0 5者 2 0只眼 (占 37 73 % ) ;术后 1周和 3个月矫正视力≥ 1 0者分别为 2 6眼 (占 49 0 5 % )和 35眼 (占 6 6 0 3 % )。术后一天和三个月平均散光为 0 6 1± 0 42D和 0 5 1± 0 37D与术前比较无统计学差异。手术并发症主要为术中后囊破裂 ( 5眼 ) ,术后晶体偏心 ( 2眼 )和黄斑囊样水肿 ( 3眼 )。结论 :经颞侧透明角膜隧道切口的二期折叠式人工晶体植入术具有手术时间短、并发症少、操作简单、视力恢复快等优点 ,适应于绝大部分的无晶体眼患者。
Objective:To investigate the methods and advantages of secondary intraocular lens (IOL) implantation through tunnel incision on the temporal clear cornea. Methods:In 50 cases (53 aphakic eyes),secondary foldable IOL implantation was performed.The temporal clear cornea was incised with the diamond knife just in the center of cornea′s peripheral vascular arcus,0 3mm deep,3 2mm long and 1 75mm wide.The following up was 6～12 months (average,8 4 months).The observation included postoperative vision,cornea′s curvature,IOL position,intraoperative complications and postoperative complications. Results:On the first day after surgery,there were 20 eyes (37 73%) of which corrected vision was better than 0 5.By one week and 3 months after surgery,there were respectively 26 eyes (49 05%) and 35 eyes (66 03%) of which corrected vision was not less than 1 0.By one day and 3 months after surgery,the average astigmatism was 0 61±0 42D and 0 51±0 37D,respectively.However,there was not statistical difference between preoperative and postoperative astigmatism.The major complications were rupture of posterior capsule during the operation (5 eyes),postoperative eccentric IOL (2 eyes) and macular edema (3 eyes). Conclusions:The advantages of the secondary foldable IOL implantation through tunnel incision on the temporal clear cornea are short operative duration,few complications,simple techniques and quick vision recovery,etc.The surgery adapts to most aphakic patients.
