LENTE DE CONTACTO SENSORA, SISTEMA PARA LA MONITORIZACION NO INVASIVA DE LA PRESION INTRAOCULAR Y METODO PAR SU MEDIDA

摘要

The invention is characterised in that it includes a truncated contact lens (1) having a truncation plane parallel to the base of the contact lens and a centrally disposed polymer nanocomposite material (2) joined to the perimeter of the truncated zone, said material being sensitive to pressure changes, biocompatible and transparent and including contact electrodes (3). The invention is also characterised in that it includes means for transmitting intraocular pressure measurement data to an external system. The invention also relates to an intraocular pressure measurement method using said lens, consisting of: i) positioning the sensor contact lens on an eye in order to determine the intraocular pressure thereof; ii) supplying a direct current between the external electrodes; iii) measuring ?V between the internal electrodes; and iv) identifying if the value obtained is outside the linear response expressed as changes in resistivity of the polymer nanocomposite material. The invention further relates to a telemetry system including said lens.
