目的 应用经角膜隧道切口的改良手术方法取出晶状体玻璃体切割 (PPV +PPL)术后填充的眼内硅油 ,考察并评价其临床效果。方法 对 1 8例曾行PPV +PPL的无晶状体硅油填充眼行经角膜隧道切口的硅油取出术。局麻下 ,将灌注管固定于术眼颞下方平坦部处灌注 ,用剪短至5mm左右长的 2 0G静脉穿刺套管经透明角膜隧道穿刺口负压抽取硅油 ,并在显微镜下仔细置换出残留的小油滴。结果 1 8例眼内硅油均一次成功取出 (成功率 1 0 0 % )。主要并发症有 :1 4眼术后低眼压 ( 77. 8% ) ;7眼玻璃体混浊 ( 38. 9% ) ;1眼视网膜脱离复发 ( 5 6 % )。结论 经角膜隧道切口取出无晶状体眼内硅油的改良手术 ,方法简单有效而且并发症少 ,具有较广泛的临床应用价值。
Objective To investigate the clinical effect of intraocular silicone oil filled with vitrectomy (PPV + PPL) after corneal tunnel incision with modified surgery. Methods Fourty-eight cases of aphakic silicone oil filled PPV + PPL underwent ocular tunnel incision silicone oil extraction. Under local anesthesia, the perfusion tube was fixed in the flat part of the temporal eye under perfusion, with a short length to about 5mm long 20G venipuncture cannula through the transparent corneal tunnel puncture negative pressure extraction silicone oil and carefully replaced under a microscope Residual small oil droplets. Results 18 cases of intraocular silicone oil were successfully removed (success rate 100%). The main complications were 14 postoperative IOP (77.8%), 7 vitreous opacities (38.9%) and 1 retinal detachment (56%). Conclusion Corneal tunnel incision removal of intraocular silicone oil improved surgery, the method is simple and effective and less complications, has a wider range of clinical value.
