摘要
目的探讨在曾做过玻璃体切除手术眼再施行超声乳化白内障摘除术时的临床特征及其并发症和视力预后。方法回顾研究作者3年内对曾行玻璃体切除手术后并发白内障的32例(32只眼)患者再施行白内障超声乳化术。资料包括术前特征、术中发现、术后并发症,还对比分析了最终视力与术前测定的激光视网膜预测视力。结果在所有做过玻璃体切除的术眼,均可发现术中有晶状体悬韧带松弛、前房加深及前房波动大和瞳孔变化大。在12只硅油眼中有3只眼在术中有少量硅油进入前房。未见有严重威胁视力的并发症出现,最后视力较术前多有明显提高。结论白内障超声乳化术对玻璃体切除术后眼的白内障是一种安全有效的方法,但必须注意小心处理一些特殊情况,包括丧失玻璃体支持、后囊膜不稳定及悬韧带脆弱、前房深度异常波动、玻璃体填充硅油进入前房等。
Objective To report our experience of phacoemulsification in patients who had previously undergone pars plana vitrectomy surgery. Methods A retrospective study of 32 consecutive cataract operations on vitrectomised eyes per-formed in a three years period by a single sergeon. Data was collected on preoperative characteritics ,intraoperative observations , postoperative complications. The final visual acuity and its correlation to the preoperative potential acuity msiliconcarbide disk（PAM） visual acuity were analysed. The mean interval from PPV to phacoemulsification was 22 months. Result Zonular laxity with abnormal deepening of anterior chamber and small pupils was noted in all eyes that had undergone pars plana vitrectomies . Out of 12 eyes with silicon oil ,3 eyes had little silicon oil into anterior chamber from vitreous chamber . No sight threatening complications was.encountered and final visual acuity was improved . Conclusion Phacoemulsification is a ssfe and effective surgical procedure in post-vitrectomised eyes . But phacoemulsification in the vitrectoraised eye present a special challenge , which include the loss of vitreous support , unstable posterior capsular , weakened zonules ,the silicon oil into anterior chamber from vitreous chamber.
