A system and method for measuring biomechanical properties of tissues without external excitation are capable of measuring and quantifying these parameters of tissues in situ and in vivo. The system and method preferably utilize a phase-sensitive optical coherence tomography (OCT) system for measuring the displacement caused by the intrinsic heartbeat. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. Preferably, the method is used to detect tissue stiffness and to evaluate its stiffness due to intrinsic pulsatile motion from the heartbeat. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases and evaluating the efficacy of therapies.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user’s body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can include at least one source for producing mechanical waves of several frequencies from a distance to the eye of the patient to generate at least one surface wave to the eye, a detector for detecting at least one surface wave from a distance from the eye to extract surface wave information, and a device for determining pressure information of the eye based on the surface wave information.

Systems and method are provided which enhance ophthalmological surgical procedures. Systems may include camera(s) configured to capture and magnify eye image(s) (possibly stereoscopic), a tissue position and orientation (P&O) tracker configured in to track a P&O of a specified eye tissue, a tool P&O tracker configured to track a P&O of treatment tool(s) and derive a tool tip pointing vector therefrom, a processing unit configured to calculate an intersection between the tool tip pointing vector and the specified eye tissue and to relate spatially optical coherence tomography (OCT) image(s) of the eye tissue to the tool tip location and/or to the intersection, and a display module configured to display the magnified image(s) of the eye tissue with the OCT image(s) associated therewith according to the spatial relation. An OCT imager may be mounted on the tool tip to provide the OCT image(s) in real time.
