摘　　要：当晶状体悬韧带有异常时,白内障手术的安全性将受到严重的威胁,手术中玻璃体脱出、囊膜破裂、晶状体皮质残留及人工晶状体脱位等风险大大增加。晶状体囊袋张力环和相关的囊膜内装置的使用,使眼科医生能够在复杂的白内障手术中轻松维持囊袋的稳定性,增强了眼前节手术的可控性,减少或减轻了术中、术后并发症,改善了悬韧带异常相关疾病的预后。随着设计和材料的不断进步,晶状体囊袋张力环的适应证逐渐扩展,尤其对于高度近视患者而言,可维持人工晶状体位置的稳定,辅助支撑悬韧带松弛部位,抑制术后残留的晶状体上皮细胞的迁移和增生,改善患者视觉质量以及降低视网膜脱离的发生率。When there are anomalies in the zonules,the safety of cataract surgery is significantly compromised,leading to increased risks of vitreous prolapse,capsular rupture,residual lens cortex,and dislocation of the intraocular lens(IOL).The use of capsular tension rings(CTRs)and related intraocular devices allow ophthalmologists to maintain the stability of the capsular bag easily during complex cataract surgeries,enhancing the controllability of anterior segment procedures and reducing or alleviating intraoperative and postoperative complications.Moreover,they improves the prognosis of zonular anomalies related conditions.With continuous advancements in design and materials,the indications for capsular tension rings are expanding gradually.Especially for highly myopic patients,CTRs can effectively stabilize the position of the IOL,provide additional support to the relaxed zonules,inhibit migration and proliferation of residual lens epithelial cells,and improve patients'visual quality while reducing the incidence of retinal detachment post-surgery.
