More Information
Summary:The invention is characterized in that it comprises a truncated contact lens (1), whose truncation plane is parallel to the base of said contact lens, and a polymeric nanocomposite material (2) centrally disposed and attached to the perimeter of the truncated area, said material being sensitive to pressure changes, biocompatible and transparent, and including contact electrodes (3), and in that it also comprises means for transmitting IOP measurement data to an external system. The invention also relates to a method for measuring IOP using said lens comprising: i) placing said sensor contact lens in the eye to determine its intraocular pressure; ii) providing a direct current value between external electrodes; iii) V measurement between internal electrodes; and iv) identifying whether the value obtained is outside the linear response, expressed in changes of resistivity, of the polymeric nanocomposite material. The invention also relates to a telemetry system comprising said lens.
