摘　　要：目的　探讨外伤性晶状体后脱位于后段玻璃体腔的处理方法。方法　对 9例外伤性晶状体后脱位于后段玻璃体腔行玻璃体手术晶状体切除术 ;玻璃体手术加粘弹剂晶状体摘出术 ,观察手术疗效及并发症。结果　 8例晶状体成功取出 ,3例行人工晶状体睫状沟固定术。术前视力为光感至 0 0 6。随访 6月～ 2年 ,人工晶状体睫状沟固定 3例视力均在 0 1以上 ,最佳矫正视力达 1 2 ;未行人工晶状体固定的 6例矫正视力为光感～0 3。结论　外伤性后脱位于后段玻璃体腔的晶状体应摘出 ,玻璃体切除配合玻璃体腔内注入粘弹剂 (透明质酸钠 )Objective To study the way to manage lens dislocated into vitreous cavity.Methods Two methods of vitreous surgery were applied for 9 cases with traumatic complete luxation of lens into the vitreous cavity:vitreous surgery with resection of lens in 2 cases,vitreous surgery combined with viscoelastics applied for lens removal in 6 cases.Results The dislocated lenses were removed successfully in 8 cases,and 3 IOLs were fixed at ciliary sulcus.The preoperative visual accuities were light perception to 6/100.Postoperatively,the patients were followed 6 months to 2 years.In the cases with ciliary sulcus fixation of IOLs,the corrected visual acuities were 6/60 to 6/5.In the 6 cases without fixation of IOLs,the corrected visual acuities were light perception to 6/20.Conclusion Vitreous surgery combined with the use of viscoelastics in the vitreous cavity is a good way for the treatment of a case with lens dislocated in the vitreous cavity and the lens should be removed.Visual acuity can be improved significantly by the fixation of IOL at ciliary sulcus
