目的 寻找在葡萄膜炎并发白内障术中阻止术后虹膜后粘连的方法。方法 术中将粘弹剂衬于虹膜后表面与人工晶状体之间 ,使虹膜悬浮于人工晶状体上 1mm。结果 术后 3月复查 ,术中置留粘弹剂的 2 4眼中无虹膜后粘连 2 2眼占 92 % ,虹膜后粘连 <90°范围 1眼占 4% ,虹膜后粘连 90°～ 180°1眼占4%。视力提高 0 5以上 18眼占 75 % ,高于对照组 ( χ2 =2 0 .2 5 ,P<0 .0 1) ,差异有显著意义。结论 粘弹剂术中置留可以有效地预防葡萄膜炎并发白内障术后虹膜后粘连。
Objective To find a way to prevent post-iris adhesions in uveitis complicated with cataract surgery. Methods During the operation, the viscoelastic agent was lined between the posterior surface of the iris and the intraocular lens so that the iris was suspended in the intraocular lens by 1mm. Results Three months after operation, 22 eyes of 22 eyes with iris posterior adhesions were 92% underwent intraocular viscoelastic fixation, 1% of eyes with posterior iridia at 4%, and posterior iris posterior adhesion of 90 ° ~ 180 ° 1 eye accounted for 4%. Visual acuity increased more than 5 5 18 eyes accounted for 75%, higher than the control group (χ2 = 20.25, P <0.01), the difference was significant. Conclusion Viscoelastic surgery can effectively prevent uveitis and post-iris adhesion after cataract surgery.
