A binocular loupe on the principle of the prismatic telescope, small in size and light in weight, and which can be firmly by straps to the head of the doctor, has been developed for use in operative ophthalmology, for the clinical visit, consultation and in the office. Its optic properties greatest possible distance from the work which can be varied with additional lenses, variable magnification even into the region of the smallest biomicroscopes with a relatively large angle of vision, good mobility with regard to the object of vision with unchanged adjustment, simultaneous possibility of using semispectacles for presbyopia and easy swinging of the instrument out of and into the line of vision with one hand movement make this instrument very appropriate for the reasons for which it was developed and makes possible also - especially in the surgery of injured eyes, exact observation and assessment of the eye and performance of operations where no operating microscope is present with much greater magnification as that obtained with a customary loupe. This instrument occupies the spare between the possibilities of use of the loupe and the biomicroscope and can in addition be used in the boundary areas of use of the other instruments with great advantage.
一种基于棱镜望远镜原理的双目放大镜已被研发出来，用于眼科手术、临床诊疗、会诊及门诊。它体积小、重量轻，可通过带子牢固地固定在医生头上。其光学特性包括：可通过附加镜片改变与工作物的最大可能距离；即使在最小生物显微镜的区域也能实现可变放大倍率，且视角相对较大；在调节不变的情况下，对观察对象具有良好的移动性；同时可使用老花镜；用单手动作就能轻松地将仪器移出和移入视线。这些特性使该仪器非常适合其研发目的，尤其在伤眼手术中，能在没有手术显微镜的情况下，以比传统放大镜大得多的放大倍率对眼睛进行精确观察、评估和手术操作。该仪器填补了放大镜和生物显微镜使用可能性之间的空白，此外，在其他仪器使用的边界区域也能发挥很大优势。
