A description is made of the uses of the Hruby lens, the Goldmann 3-mirror lens, and the recently introduced Volk +90D lens for biomicroscopic examination of the fundus. The optical principles and clinical techniques of each lens are discussed along with their advantages and disadvantages. The Hruby lens is shown as a convenient technique that is easy to learn. Hruby lens benefits are qualified due to its relatively low field of view and due to the need for excellent patient cooperation to achieve the exact retinal view desired. The Goldmann 3-mirror contact lens is supported as an important clinical technique because of its reliability in providing clear views of the central and peripheral retina. The Volk lens is cited as providing the widest retinal field of view possible with the biomicroscope without the need for corneal contact.
本文描述了用于眼底生物显微镜检查的赫鲁比透镜、戈德曼三面镜透镜以及最近推出的沃尔克+90D透镜的用途。讨论了每种透镜的光学原理、临床技术及其优缺点。赫鲁比透镜被证明是一种易于学习的便捷技术。由于其视野相对较窄，且需要患者高度配合才能获得所需的精确视网膜视图，因此其优势受到一定限制。戈德曼三面镜接触镜因其能可靠地提供中央和周边视网膜的清晰视图而被视为一项重要的临床技术。沃尔克透镜被认为在不接触角膜的情况下，能通过生物显微镜提供尽可能宽的视网膜视野。
