  • Ocular pressure measuring device
    Publication number: 20030078487
    Abstract: An intraocular pressure measuring device including a pressure sensor that is dimensioned to be placed in a cornea or sclera. An intraocular pressure measuring system that includes a pressure sensor positioned in a cornea or sclera and an external device outside the eye, the external device wirelessly communicating with the pressure sensor. A method for measuring intraocular pressure that includes inserting a pressure sensor in a cornea or sclera and sensing intraocular pressure. An ophthalmic device that includes an exoplant and an intraocular pressure sensor connected to the exoplant. An ophthalmic instrument that includes a device adapted to wirelessly interrogate a medical apparatus implanted in the cornea or sclera. A propagating signal for determining intraocular pressure is also described.
