超声乳化致晶体碎块坠入玻璃体腔的手术治疗

目的评价玻璃体切除术治疗晶体坠落物的效果。方法对１９９２年１０月至１９９５年１０月澳大利亚墨尔本皇家维多利亚眼耳医院所做５８例玻璃体切除术治疗晶体坠落物的病例,随访３个月以上资料进行回顾分析。结果最后随访时残留囊样黄斑水肿３例（５．２％）,视网膜脱离２例（３．４％）,低眼压ｌ例（１．７％）,其余并发症均消失。其中３８只眼（６５．５％）最后视力≥０．５,仅６只眼视力＜０．０５。结论白内障手术中一旦发生晶体成分坠落于玻璃体内,宜妥善处理眼前段,可能时植入人工晶体,并尽快行玻璃体切除术治疗,一般可取得良好效果

An analysis of treatment of intravitreal lens fragments following phacoemulsification

Objective To observe and evaluate the outcome of vitrectomy in the treatment of dropped lens fragments. Method Retrospectively the authors reviewed and analyzed 58 cases of dropped lens fragments that were treated with vitrectomy from October 1992 to October 1995 in Royal Victoria Eye and Ear Hosptial, Melbourne, Australia and followed for at least 3 months. Results At the last follow up, the remained complications were cystoid macular edema in three cases (5.2%), retinal detachment in two cases (3.4%) and hypotony in one case (1.7%). Other complications were all resolved. The final vision was significantly better than that before vitrectomy. There were 38 eyes (65.5%) with final visual acuities of 0.5 or better, and only 6 eyes (6.9%) with <0.05. Conclusion Once the lens fragments are dropped into the vitreous during phacoemulsification, the ocular anterior segment should be properly managed, if possible intraocular lens is inserted, and then vitrectomy should be performed as soon as possible. Generally, with the above method good therapeutic effects can be obtained.
