Abstract: A bottom surface with an adhesion surface including a plurality of micro-protrusions, or an adhesive adhered to the bottom surface; a pressure monitoring device configured to measure intraocular pressure of an eye and generate a signal representing the measured pressure; and a transmitter configured to transmit the signal. The bottom surface is arranged to secure the sensor to: an outer surface of a conjunctiva for the eye without penetrating the conjunctiva; or an outer surface of a sclera for the eye without penetrating the sclera.

Abstract: A multiple focal length transducer comprising a first end allowing cooperable attachment to an ultrasound bio-microscope. A second end allowing contact with a water bath. An adjustable connecting portion allowing multiple focal lengths. The adjustable connecting portion may be allowed to flex similar to an accordion. The multiple focal length transducer is preferably produced to be sterile from medical grade silicone and is disposable.

Abstract: A sensor and method of use thereof for continuously measuring intraocular pressure (IOP) is disclosed. The sensor is designed to be adhered to the sclera of an eye and may be passive or active, with or without flash memory or other data storage media. The sensor includes a pressure monitoring device that abuts the sclera and generates a signal that may be correlated to IOP. The sensor then transmits this signal to either a receiver in a base unit or to flash memory within the sensor. In exemplary embodiments the pressure monitoring device includes a strain array and/or a resonant circuit, but any pressure monitoring device may be used. In one embodiment the sensor includes a microprocessor unit that controls the other electrical components of the sensor and directly interrogates the pressure monitoring device for a each IOP measurement.
