Japanese Patent JP3008197
Kind Code:
B2
Abstract:
The ophthalmological instrument serves for examining the background (7) of the eye with simultaneous determination of intraocular pressure. A transparent contact member (1) has a concavely curved surface (13) adapted to the curvature of the cornea (11) of the eye (6). In the center of this curved surface (13), a transparent pressure transmitting element (25) is arranged which acts on a pressure sensor (23) by way of a cavity (19) filled with a liquid (26). The contact member (1) is designed as an imaging optical component forming together with the observation optic (9) an observation device for examination of the eye background (7). Additional pressure sensors (27) are located at the rim of the concave curvature (13) of the contact member (1), these additional pressure sensors, on the one hand, monitoring an exact positioning of the contact member (1) and, on the other hand, eliminating falsification of the measured value, caused by the contact pressure of the contact member (1) against the eye (6), by means of an electronic measuring data evaluation.
