  • Patent number: 4523821
    Abstract: In a device for examining anterior sections of the eye, based on the Scheimpflug principle, an electric receiver is provided in the imaging-beam path for electronic evaluation of results of the examination. Various meridian sections in the patient's eye are produced by means of a rotatable prism. A fixation object and a graticule in the illumination beam path enable easy reproducibility of measurement results, as well as facilitating follow-up examinations which seek to observe the same eye for changes, from one examination to a later examination.
