To describe a flapless/grooveless technique for four-point refixation of a dislocated intraocular lens (IOL) with four fenestrated haptics.
An intraocular suture looping technique was performed with the assistance of two 27-gauge needles. A looping needle was passed into the eye through paracentesis and was used to loop both fenestrated haptics on the same side with an 8-0 polypropylene thread. A guiding needle was used to guide the looping needle out of the eye at the scleral fixation sites. After looping each pair of fenestrated haptics on nasal/temporal sides with 8-0 polypropylene sutures, the IOL was refixated by definitive knotting. The exterior suture ends were buried into the sclera without the creation of scleral flaps/grooves.
The technique was employed in four eyes (three patients). The mean postoperative follow-up period was 13.8 ± 2.2 months. Postoperatively, the IOLs of all the eyes remained well positioned and stable. The postoperative visual acuities of all the eyes were improved. No suture erosion, hypotony, scleral atrophy, chronic inflammation, retinal tears, and/or detachments were observed within the follow-up period.
The present technique provides minimal surgical invasion for the transscleral refixation of a dislocated IOL with four fenestrated haptics.
描述一种用于四点固定有四个带孔袢的脱位人工晶状体(IOL)的无瓣/无沟技术。
在两根27号针的辅助下进行眼内缝线环扎技术。一根环扎针通过穿刺进入眼内,并用8-0聚丙烯线环扎同一侧的两个带孔袢。一根引导针用于在巩膜固定部位引导环扎针穿出眼外。在用8-0聚丙烯缝线分别环扎鼻侧/颞侧的每对带孔袢后,通过最终打结将IOL重新固定。外部缝线末端埋入巩膜,不制作巩膜瓣/沟。
该技术应用于4只眼(3例患者)。术后平均随访时间为13.8±2.2个月。术后,所有眼的IOL均保持良好位置且稳定。所有眼的术后视力均有提高。随访期间未观察到缝线侵蚀、低眼压、巩膜萎缩、慢性炎症、视网膜裂孔和/或视网膜脱离。
本技术为经巩膜重新固定有四个带孔袢的脱位IOL提供了最小的手术侵袭。
