Drying of the cornea during surgery, which causes poor visibility of the fundus, is one of the most serious problems when using a noncontact-type wide-angle viewing system. This study used a newly commercialized lens for observing the fundus with a noncontact wide-angle viewing system. The lens used has a very thin meniscus made of polymethyl methacrylate and a large outer diameter. Following the application of viscoelastic material, the lens can be put on the cornea without using a contact lens fixation ring. The larger diameter and lightweight characteristics of the new lens contributed to the overall stabilization. The smooth surface of this lens was able to achieve an intraoperative view of good quality not only during vitrectomy but also during scleral buckling procedures.
手术过程中角膜干燥会导致眼底可视性差，这是使用非接触式广角观察系统时最严重的问题之一。本研究使用了一种新商业化的镜片，用于通过非接触式广角观察系统观察眼底。所使用的镜片具有由聚甲基丙烯酸甲酯制成的非常薄的弯月面和较大的外径。在应用粘弹性材料后，无需使用隐形眼镜固定环即可将镜片放置在角膜上。新镜片较大的直径和轻质特性有助于整体稳定。该镜片光滑的表面不仅在玻璃体切除术中，而且在巩膜扣带手术中都能够实现高质量的术中视野。
