WIRELESS INTRAOCULAR PRESSURE MONITORING DEVICE, AND SENSOR UNIT AND READER UNIT THEREOF

Abstract

A wireless intraocular pressure monitoring device includes a sensor unit and a reader unit. The sensor unit includes: a soft contact lens for wearing on a cornea such that a curvature of the soft contact lens corresponds substantially to that of the cornea; an inductor embedded in the soft contact lens and having an inductance that corresponds to intraocular pressure when the soft contact lens is worn on the cornea; and a wireless transceiver module operable to generate an oscillation signal having a frequency dependent on the inductance of the inductor and to wirelessly transmit the oscillation signal. The reader unit is operable to receive and convert the oscillation signal into an output signal corresponding to the intraocular pressure.
