To introduce a simplified method to remove silicone oil via limbus of corneal after previous lensectomy-vitrectomy.
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.
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.
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.
介绍一种在先前晶状体切除 - 玻璃体切除术后经角膜缘取出硅油的简化方法。
51只眼在先前晶状体切除 - 玻璃体切除术后，通过单通道平坦部或角膜缘切口接受改良手术以清除硅油。采用25G注射器针头经平坦部或角膜缘进行局部麻醉并通过角膜缘上方切口清除硅油。
所有手术在清除硅油方面基本成功。所有患者均出现早期低眼压并发症，4只眼（4/51，7.8%）发生视网膜脱离，2只眼（2/51，3.9%）穿刺点少量出血。视网膜复位稳定的患者术后视力显著提高（P < 0.05）。
在先前晶状体切除 - 玻璃体切除术后经单通道平坦部和角膜缘或角膜缘切口的手术，因其操作简单、疗效好且并发症少，对于无晶状体眼硅油填充的取出是有用的。
