When silicone oil, a hydrophobic agent, is injected into the vitreous cavity during the course of vitrectomy operations, often some escapes outside the eye, and a mixture of oil and water forms under the infusion contact lens, markedly interfering with visibility. We found that a viscous solution of methylcellulose 1.75% in saline used as the infusion contact lens irrigant, instead of a saline solution alone, can prevent silicone oil from entering under the contact lens, thus avoiding this difficulty.
在玻璃体切割手术过程中，当向玻璃体腔注入作为疏水介质的硅油时，硅油常逸出眼外，在灌注接触镜下形成油水混合物，显著影响视野。我们发现，用1.75%甲基纤维素的粘性盐溶液作为灌注接触镜冲洗液，而非仅用盐溶液，可防止硅油进入接触镜下方，从而避免这一难题。
