摘要
目的探讨后房型人工晶体后脱位至后段玻璃体腔的处理方法。方法对１５例人工晶体严重后脱位的患者行玻璃体手术加机械人工晶体取出术；玻璃体手术加全氟化碳液人工晶体取出术；玻璃体手术加人工晶体取出及人工晶体睫状沟固定等手术，观察手术疗效及并发症。结果１５例患者人工晶体均成功取出，５例行人工晶体睫状沟固定术。术前视力为光感至手动。随访３个月至３年，人工晶体睫状沟固定５例患者视力均在０２以上，最佳视力０８；未行人工晶体固定的１０例患者矫正视力在００２～０４之间。术后并发症有视网膜脱离１例，轻度眼内出血２例，反应性葡萄膜炎３例。结论人工晶体严重后脱位应予取出，玻璃体手术处理是其最佳方案，人工晶体睫状沟固定可提高患者视功能。
Objective To study the way to manage intraocular lenses (IOLs) dislocated into vitreous cavity. Methods Three methods of vitreoretinal surgery were applied for 15 cases with severe dislocation of IOL into vitreous cavity: vitreoretinal surgery combined with simple IOL removal in 7 cases (simple group), vitreoretinal surgery combined with liquid perfluorocarbon (PFCL) applied for IOL removal in 3 cases and vitreoretinal surgery combined with IOL removal and fixation of IOL at ciliary sulcus in 5 cases. Results The dislocated IOLs were removed successfully in all cases. The preoperative visual acuities were light perception to hand movement. Postoperatively, the patients were followed for 3 months to 3 years. In the cases with ciliary sulcus fixation of IOL, all their visual acuities were above 20/100 and the best visual acuity was 20/25. In the 10 cases without fixation of IOL, the corrected visual acuities were 20/1000 to 20/50. The complications were retinal detachment in 1 case, slight vitreous hemorrhage in 2 cases and temporary uveitis in 3 cases. Conclusion Vitreous surgery is the best way for the treatment of a case with IOL severely dislocated into the vitreous cavity, and such an IOL should be removed. Visual acuity can be improved significantly by the fixation of IOL at ciliary sulcus
