Safe implementation of planned cataract extraction calls for perfect instruments but also for a high standard surgical microscope with coaxial illumination to produce a red reflex on the pupil. Microscopes of Zeiss Jena 310 and 311, which are used in the majority of ophthalmological departments, lack this type of illumination and this impedes wider application of extracapsular cataract extractions. The author gives an account on the possibility of installing coaxial illumination ex post. He mentions briefly a design presented in Dĕcín and suggests his own modification which he tested. As optic conductors are not available and are the basis of the equipment, the author elaborated a solution of his own and uses the proposed equipment during operations. It does not require optic cables with optic terminals, nor a new source of light.
安全实施计划性白内障摘除术不仅需要完美的器械，还需要一台高标准的手术显微镜，其具备同轴照明功能，以便在瞳孔上产生红色反光。蔡司耶拿310和311型显微镜在大多数眼科科室中使用，但缺乏这种照明方式，这阻碍了囊外白内障摘除术的更广泛应用。作者阐述了事后安装同轴照明的可能性。他简要提及了在德钦提出的一种设计，并给出了自己经过测试的改进方案。由于光导不可用且是该设备的基础，作者精心设计了自己的解决方案，并在手术中使用了该设备。它既不需要带有光终端的光缆，也不需要新的光源。
