目的：探讨玻璃体切割联合晶状体超声粉碎和Ⅰ期人工晶状体睫状沟固定术治疗晶状体后脱位的临床效果。 方法:对晶状体后脱位11例11眼作回顾性研究, 均采用闭合式三切口玻璃体切割联合晶状体超声粉碎和人工晶状体睫状沟固定术。 结果:所有患者均成功摘出脱位晶状体, 且视力均有提高。合并继发青光眼者, 眼压得到控制。术后并发症有角膜水肿3例, 虹膜炎症反应2例。 结论:晶状体后脱位导致视力障碍、继发性青光眼、伴有玻璃体积血时, 采用玻璃体切割联合晶状体超声粉碎和人工晶状体睫状沟固定术治疗效果良好。手术成功的关键在于选择适应证及掌握娴熟的操作技巧。

AIM:To evaluate the Clinical efficacy of pars plana vitrectomy,ultrasonication of crystalline lens combined with intraocular lens ciliary sulcus fixation for traumatic subluxated lens. METHODS:Eleven cases (11 eyes) with traumatic subluxated lens were surgically managed by pars plana vitrectomy, ultrasonication of crystalline lens combined with intraocular lenses ciliary sulcus fixation. RESULTS:The subluxated lenses were extracted successfully in the 11 eyes. All the cases had better corrected visual acuity after surgery. The postoperative complications were corneal edema in 3 cases, and iritis in 2 cases.  CONCLUSION:Combined surgery on the traumatic subluxated lens is effective, especially for the recovery of vision decrease,secondary glaucoma and vitreous hemorrhage. Proper selection of indication and skillful manipulation are key points.
