| abstract |
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) ΔV 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. |
