Summary: | Apparatus and method for measuring intraocular pressure (IOP). comprising a vibrator which transmits a vibrational energy into an eyeball through the eyelid and measures at least one of a force or phase response in the eyeball. The measurements are taken by placing the tonometer against the eyelid to induce vibration in the underlying eyeball. A force transducer coupled to the vibrator measures the response of the eyeball from which a vibrational impedance of the eye is determined. Intraocular pressure is then calculated based on the vibrational impedance. In a preferred use of the apparatus, the tonometer is calibrated against a known intraocular pressure measurement permitting the patient to take subsequent relative IOP measurements at home or otherwise outside a traditional medical setting without the need for anesthetic or fear of infection. |
