Abstract
The device (1) for measuring intraocular pressure, in particular a tonometer, has a base body (3) which has a contact surface (5; 17; 30) to be applied to the eye surface. The contour of the contact surface (5) is adapted with a certain tolerance to a standard surface of a standard eye with predetermined internal pressure. Arranged in the contact surface (5) there is a pressure-sensitive unit (7) whose contact surface (9; 23; 31) merges into the contour of the contact surface (5) of the base body (3). With the device according to the invention, the pressure actually prevailing in the eye can be precisely measured.
