    • نبذة مختصرة :
      Utilization of a contact device placed on the eye in order to detect physical and chemical parameters of the body as well as the non-invasive delivery of compounds according to these physical and chemical parameters, with signals being transmitted continuously as electromagnetic waves, radio waves, infrared and the like. One of the parameters to be detected includes non-invasive blood analysis utilizing chemical changes and chemical products that are found in the conjunctiva and in the tear film. A transensor mounted in the contact device laying on the cornea or the surface of the eye is capable of evaluating and measuring physical and chemical parameters in the eye including non-invasive blood analysis. The system utilizes eye lid motion and/or closure of the eye lid to activate a microminiature radio frequency sensitive transensor mounted in the contact device. The signal can be communicated by wires or radio telemetered to an externally placed receiver. The signal can then be processed, analyzed and stored. Several parameters can be detected including a complete non-invasive analysis of blood components, measurement of systemic and ocular blood flow, measurement of heart rate and respiratory rate, tracking operations, detection of ovulation, detection of radiation and drug effects, diagnosis of ocular and systemic disorders and the like.

    • Claim:
      1-58. (canceled)
    • Claim:
      59. An ophthalmic system comprising: a tonometer for measuring intraocular pressure; at least one of a keratometer for measuring corneal curvature, a biometer for measuring size of the eye, a device for measuring ocular rigidity and a device for measuring temperature; an electrical device altering the measured intraocular pressure based upon the at least one of the measured corneal curvature, the measured size of the eye, the measured ocular rigidity and the measured temperature to produce a corrected intraocular pressure; and a display identifying the corrected intraocular pressure.
