摘　　要：目的　探讨将囊袋张力环植入晶状体半脱位的囊袋内进行超声乳化白内障吸除术的安全性。方法　对 13例 (14只眼 )合并晶状体半脱位 (脱位范围 1/ 3～ 3/ 4象限 )的白内障患者行超声乳化白内障吸除术 ,术中注 /吸晶状体皮质时 ,将囊袋张力环送入晶状体囊袋内 ;对脱位范围 >1/ 2象限者 ,将囊袋张力环用缝线固定在巩膜上。结果　术中人工晶状体植入晶状体囊袋内 11只眼 ,植入睫状沟 3只眼 ;术后人工晶状体正位 12只眼 ,人工晶状体轻度倾斜 2只眼 ;术中常见并发症为囊袋撕裂和玻璃体脱出。结论　囊袋张力环是超声乳化白内障吸除术治疗白内障合并晶状体半脱位患者的新型辅助工具 ,它具有提高手术安全性 ,防止人工晶状体偏位 。Objective To investigate the safety of capsular tension ring implantation during phacoemul sification in the subluxated lens Methods Capsular tension ring was implanted in 13 cases (14 eyes) of subluxated lens after continuous curvilinear capsulorrhexis during phacoemulsification The luxated area was ranged from one third to three quarters of a circle The capsular tension ring was necessary to be fixated on sclera if the luxated area was larger than half quarter of a circle After the ring was implanted, phacoemulsification was performed and foldable intraocular lens (IOL) was implanted Results The capsular tension ring was successfully implanted in 14 eyes, including 11 IOLs fixated in the bag and 3 in ciliary sulcus IOL positions in 12 cases were normal, and in 2 eyes, had slight tilt The most common intraoperative complication was the rupture of capsular bag, and secondly, the loss of vitreous body Conclusion Capsular tension ring implantation is safe in the patient of lens subluxation during phacoemulsification It can prevent the IOL decentration and decrease the vitreoretinal complication
