摘要：
An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can detect 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 can produce acoustic, nonlinear acoustic, mechanical or a nonlinear mechanical wave from a distance, coupling to the eye to generate at least one surface wave. Upon triggering data acquisition, at least one surface wave from a distance from the eye can be detected to extract surface wave information with pressure information of the eye being based on the surface wave information.
