Abstract: A device for continuously monitoring the intraocular pressure in an eye, which includes a scleral contact lens having a pressure transducer thereon for measuring intraocular pressure. The lens is sized to fit within the sclera of an eye for positioning the pressure transducer in fixed contact with the sclera in the superior temporal quadrant of the eye in the superior cul-de-sac during movement of the eye. The pressure transducer includes at least one semiconductor strain gauge crystal adapted to generate an electrical resistance which is responsive to inraocular pressure. A projection is provided for scleral indentation and is positioned to transmit response to intracular pressure to the crystal. A battery powered memory unit is mounted in the lens in non-scleral contact for recording measurements of pressure by the transducer over a predetermined period of time, preferably by, measuring the resistance through the crystal. The crystal is fixed to a flexible membrane forming a mounting on the contact lens.
