Noncontact wide-angle viewing of the fundus during vitrectomy has heretofore relied on an image inverter and a 90-diopter lens fixed with a tube under the microscope. A new device in which the 90-diopter lens is not connected to the microscope but, rather, is connected to an independent support system is described. This device offers many advantages: (1) focusing on the various parts of the eye during vitreous surgery need not be done manually but is achieved by the up or down movement of the microscope, (2) translation of the microscope is easier during tilting of the eye, (3) a lateral slit-lamp can be easily added for illumination of the fundus, and (4) there is no risk that the 90-diopter lens will touch the cornea.
迄今为止,玻璃体切除术中对眼底进行非接触式广角观察依赖于图像倒置器以及在显微镜下用管道固定的90屈光度透镜。本文描述了一种新装置,其中90屈光度透镜并非与显微镜相连,而是与一个独立的支撑系统相连。该装置具有诸多优点:(1)玻璃体手术期间无需手动聚焦于眼睛的各个部位,而是通过显微镜的上下移动来实现;(2)在眼球倾斜时显微镜的平移更容易;(3)可以轻松添加侧面裂隙灯以照亮眼底;(4)不存在90屈光度透镜接触角膜的风险。
