Abstract：
OBJECTIVE: To describe the facilitated trailing haptic externalization technique for intrascleral intraocular lens (IOL) fixation.
METHODS: In this technique, first the direction of the 4-5 mm tip of the trailing haptic is straightened with the help of forceps. After the second needle enters the posterior chamber, the edge of the IOL optic is pushed towards the opposite scleral tunnel with the needle. The trailing haptic approaching the center from the periphery and the straightened distal part of the haptic towards the direction of the needle facilitate the relatively easily and gently placing of the haptic into the lumen with a one-time use of forceps.
RESULTS: This technique was performed on 65 eyes of 58 patients, with a mean patient age of 53.0 ± 14.6 years (range, 22-78). No complications such as endothelial touch, vitreous loss, iris or ciliary body damage, and hyphema were encountered during surgery. The mean operation duration was 14.8 ± 2.3 min (range, 12-20). In the postoperative period, there was only mild postoperative anterior chamber reaction in all eyes. Postoperative transient intraocular pressure (IOP) elevation that responded well to topical antiglucomatous therapy was observed in only two cases (3%). No patient developed haptic exposure, IOL dislocation, iris capture, postoperative hypotony, vitreous hemorrhage, choroidal effusion, cystoid macular edema, or retinal detachment.
CONCLUSIONS: The facilitated trailing haptic externalization technique provides a safer, simpler, and minimally invasive surgery without significant complications while easing the surgical difficulties of the Yamane technique.

摘要：
目的：描述用于巩膜内人工晶状体（IOL）固定的促进拖曳触觉外化技术。
方法：在这种技术中，首先，在镊子的帮助下，将尾部触觉部的4-5毫米尖端的方向拉直。第二根针进入后房后,用针头将IOL光学器件的边缘推向相对的巩膜隧道。从周边接近中心的尾部触觉件和朝向针的方向的触觉件的伸直的远侧部分有助于利用一次使用镊子将触觉件相对容易且温和地放置到管腔中。
结果：该技术在58例患者的65只眼中进行，患者平均年龄为53.0±14.6岁(范围，22-78).无内皮触碰等并发症，玻璃体丢失,虹膜或睫状体损伤，术中出现前房积血。平均手术时间为14.8±2.3分钟(范围，12-20).在术后期间，所有眼睛仅有轻度的术后前房反应。仅在2例（3％）中观察到对局部抗葡萄胎治疗反应良好的术后短暂性眼内压（IOP）升高。没有病人出现触觉暴露，人工晶状体脱位,虹膜捕获,术后低张力,玻璃体出血,脉络膜积液,黄斑囊样水肿，或者视网膜脱离.
结论：促进拖尾触觉外化技术提供了一种更安全的，更简单，和微创手术无明显并发症，同时缓解了Yamane技术的手术困难。
