An object of the invention is an intraocular pressure measurement arrangement for measuring pressure of an eye (202) of a patient. The arrangement comprises at least one source (210) for producing an acoustic or a mechanical wave from a distance coupling to the eye (202) of the patient to produce surface waves of several frequencies by utilizing at least one of a patient heartbeat and breathing, means (212) for detecting at least one surface wave from a distance (201) from the eye (202) to extract surface wave information, and means (216) for determining pressure information of the eye based on said surface wave information.
