An object of the invention is an intraocular pressure measurement arrangement for measuring pressure of an eye (202) of a patient. The arrangement comprises means for detecting at least one of acoustic reflectivity, optical reflectivity, optical path difference, positioning of intraocular pressure measurement arrangement with respect to the eye, orientation of intraocular pressure measurement arrangement with respect to the eye, shape of cornea and corneal thickness, at least one source for producing at least one of acoustic, nonlinear acoustic, mechanical and a nonlinear mechanical wave from a distance (200) coupling to the eye (202) of the patient to generate at least one surface wave to the eye, means for triggering data acquisition of the pressure measurement arrangement, means for detecting at least one surface wave from a distance (201) from the eye (202) to extract surface wave information, and means for determining pressure information of the eye based on said surface wave information. |
