To report the results of sutureless scleral fixation of a posterior chamber intraocular lens (IOL) by using our developed simple technique.
We retrospectively reviewed the medical records of 48 eyes of 47 patients who underwent sutureless intrascleral IOL fixation by using our modified technique. A 25-gauge microvitreoretinal knife was used to perform sclerotomies and create limbus-parallel scleral tunnels with lamellar dissection in which the haptics were fixed.
The IOLs were fixed and centered well. The mean follow-up period was 26.7 months. Postoperative complications included smooth vitreous hemorrhage in four eyes (8.3%), cystoid macular edema in two eyes (4.2%), and iris capture of the IOL in two eyes (4.2%). No other complications, such as breakage of the IOL, spontaneous IOL dislocation, or retinal detachment, were detected during the follow-up period.
The lamellar dissection of the limbus-parallel scleral tunnel can simplify the forceps-assisted introduction of the haptics into the scleral tunnel, and this technique seemed to be safe.
报告采用我们研发的简单技术进行后房型人工晶状体（IOL）无缝线巩膜固定术的结果。
我们回顾性分析了47例患者48只眼采用改良技术行无缝线巩膜内IOL固定术的病历。使用25G微型玻璃体视网膜刀进行巩膜切开，并通过板层分离创建与角膜缘平行的巩膜隧道，将IOL袢固定于其中。
IOL固定良好且居中。平均随访时间为26.7个月。术后并发症包括4只眼（8.3%）发生轻度玻璃体积血，2只眼（4.2%）出现黄斑囊样水肿，2只眼（4.2%）发生IOL的虹膜夹持。随访期间未发现其他并发症，如IOL破裂、IOL自发脱位或视网膜脱离。
与角膜缘平行的巩膜隧道板层分离可简化镊辅助将IOL袢引入巩膜隧道的操作，且该技术似乎是安全的。
