简化的无晶状体眼内硅油取出术

目的 :介绍一种晶状体玻璃体切割术后简化的经角膜缘眼内硅油取出术。方法 :复杂性视网膜脱离经历晶状体玻璃体切割、气液交换、硅油充填联合手术患者 5 1例 ,硅油充填时间 2～ 34(平均 4 .5± 2 .3)个月。可确定视网膜状况稳定者 4 2眼。用 2 5G针头插入平坦部或角膜缘穿刺作灌注 ,同时由角膜缘穿刺取硅油。结果 :眼内硅油一次取出成功 ,视网膜状况稳定者视力显著提高 (P <0 .0 5 ) ,术后眼压基本正常 ,角膜带状变性者角膜混浊减轻。术后均有暂时性低眼压 ,视网膜再脱离 4眼 (4 / 5 1 ,7.8% ) ,巩膜穿刺口出血 2眼 (2 / 5 1 ,3.9% )。结论 :本方法简单、易掌握、疗效肯定 ,减少了巩膜穿刺创口及并发症的发生

Modification of silicone oil removal via limbus of corneal with aphakia

Objective To introduce a simplified method to remove silicone oil via limbus of corneal after previous lensectomy vitrectomy. Methods Fifty one eyes received the modified procedures to eliminate silicone oil via one pars plana or limbus incision after previous lensectomy vitrectomy. Local anesthesia was performed with 25G syringe needle through pars plana or corneal limbus infusion and super limbus incisions to eliminate silicone oil. Results All operations were primarily successful in eliminating silicone oil. The complications occurred in all the patients with the early low intraocular pressure, in 4 (4/51, 7.8%) eyes with retinal detachment, and in 2 (2/51, 3.9%) eyes with less bleeding at the point of puncture. The visual acuity was significantly improved after the procedure (P< 0.05) in patients with stable retinal reattachment. Conclusion The procedure via one pars plana and limbus or limbus incision after previous lensectomy vitrectomy is useful in removing the silicone oil tamponade in aphakic eyes because of its simplicity, good curative effect,and fewer complications.
