二期张力环缝合固定治疗先天性晶状体不全脱位手术技术

Two-stage capsular tension ring fixation technique on the surgical treatment of congenital ectopia lentis

先天性晶状体不全脱位是一种较为罕见的晶状体悬韧带异常的疾病,其手术治疗极具挑战性。以人工晶状体悬吊为代表的传统手术方式易出现囊袋破裂、玻璃体疝、人工晶状体脱位和继发性青光眼等严重并发症。近年来,以重建囊袋悬韧带隔为目标,新型囊袋辅助装置的应用极大程度提高了先天性晶状体不全脱位的手术成功率。然而,以改良式张力环为代表的囊袋辅助装置在我国仍难以得到普及且操作繁琐。因此,如何最大程度利用普通张力环等最常见的装备,设计出一种安全可靠手治疗先天性晶状体不全脱位的手术方式是眼科界亟待解决的问题。本文将介绍一种二期张力环缝合固定治疗先天性晶状体不全脱位手术技术。该技术仅需使用普通张力环,具有操作简单安全、术后效果稳定和易于技术推广的优点。

Congenital ectopia lentis is a relatively rare zonular disorder of the lens,and its surgical treatment is extremely challenging.The traditional surgical procedures represented by intraocular lens suspension are prone to result in serious complications such as capsular bag rupture,vitreous hernia,intraocular lens dislocation and secondary glaucoma.In recent years,with the goal of reconstructing the capsular bag-zonules diaphragm,the application of new capsular bag-assisted devices has greatly improved the surgical success rate of congenital ectopia lentis.However,the capsular-assisted devices,such as modified capsular tension ring,are still difficult to be popularized in China and the surgical procedures are complicated.Therefore,how to maximize the use of common equipment such as normal capsular tension rings and design a safe and reliable surgical method for the treatment of congenital ectopia lentis is an urgent issue for ophthalmologists.This article aims to introduce a two-stage capsular tension ring fixation for the treatment of congenital ectopia lentis,which has many advantages such as simple and safe operation,stable postoperative effect and less requirements for special equipment,and is worth promoting in clinical practice.
