摘要

目的:本研究的目的是描述聚丙烯缝线辅助巩膜固定人工晶状体-囊袋复合体或人工虹膜-人工晶状体复合体用于晚期脱位或半脱位的人工晶状体-囊袋和人工虹膜-人工晶状体复合体的微创无创技术。方法:在这项回顾性观察研究中,我们评估了11例患者,其中10例为囊袋-人工晶状体复合体半脱位或脱位进入玻璃体腔,1例为无虹膜-人工晶状体复合体。一名资深外科医生进行了手术。麻醉后,制作4 × 4 mm结膜包膜,6-0聚丙烯缝线穿过巩膜,标记在角膜缘后2.0 mm处。缝合端烧灼成0.5 mm以下的法兰,反向插入巩膜隧道,隐藏在2mm巩膜隧道内,以确保人工晶状体的安全定位。结果:我们分析了11例脱位或脱落的囊袋-人工晶状体复合体。患者的中位年龄为67岁(44-78岁),中位随访时间为10个月(4-16个月)。男性8人(72%),女性3人(27%)。结膜切开4例(36%)。主要的是,术前诊断显示7例(63%)患者有囊袋-人工晶状体复合物脱位。所有患者的囊袋-人工晶状体复合体集中,光学相干断层扫描证实了巩膜内准确的缝合定位。随访期间未见缝合相关并发症,术后随访未见危及视力的并发症。结论:我们的技术为治疗分散或脱位的囊袋-人工晶状体复合体提供了一种简单、有效的解决方案,无需复杂的干预措施,如大角膜创面、巩膜瓣、人工晶状体置换和人工晶状体外置。

Inverted tunnel scleral fixation technique for dropped intraocular lens complex: the double-flanged suture method.

Purpose: The aim of this study is to describe a minimally invasive and atraumatic technique for managing the polypropylene suture-assisted scleral fixation of intraocular lens-capsular bag complex or artificial iris-intraocular lens complex for repositioning late luxated or subluxated intraocular lens-capsular bags and artificial iris-intraocular lens complexes.

Methods: In this retrospective and observational study, we evaluated 11 patients, including 10 patients with capsular bag-intraocular lens complex subluxation or luxation into the vitreous cavity and 1 patient with an aniridia-intraocular lens complex. A single senior surgeon performed the procedures. After anesthesia, a 4 × 4 mm conjunctival peritomy was created, and a 6-0 polypropylene suture was passed through the sclera marked 2.0 mm posterior to the limbus. The suture ends were cauterized into a flange under 0.5 mm and inserted inversely into a scleral tunnel, concealed within a 2-mm scleral tunnel to ensure secure intraocular lens positioning.

Results: We analyzed 11 patients with dislocated or dropped capsular bag-intraocular lens complexes. The patients' median age was 67 (range 44-78) years, with a median follow-up of 10 (range: 4-16) months. There were 8 (72%) men and 3 (27%) women. Conjunctival peritomy was performed in 4 (36%) patients. Predominantly, preoperative diagnoses indicated 7 (63%) patients with dislocated capsular bag-intraocular lens complexes. The capsular bag-intraocular lens complexes were centralized in all patients, and optical coherence tomography confirmed accurate suture positioning within the sclera. No suture-related complications were observed throughout the follow-up period, and no vision-threatening complications were reported during the postoperative follow-up.

Conclusions: Our technique provides a simple, effective solution for treating decentralized or dislocated capsular bag-intraocular lens complexes, eliminating the need for complex interventions such as large corneal wounds, scleral flaps, intraocular lens exchange, and intraocular lens externalization.
