1. Device for measuring intraocular pressure, comprising:
- a base body comprising a contact surface adapted to be applied to an eye surface of an eye-wall, said eye having said intraocular pressure, the contour of said contact surface is substantially a contour of a standard surface of a standard eye, and a pressure-sensitive unit having a curved contour adapted to said contour of said standard surface of said standard eye, said pressure-sensitive unit sensing intraocular pressure on said contact surface while said eye surface is adapted to said contour of said contact surface, wherein said contour is defined as a shape at which a pressure on an inside of said eye-wall and a pressure on an outside of said eye-wall are equal in the region of the contact surface.

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.
