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) ?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.

Abstract: The present invention relates to a system for the rapid determination of the degree of hepatic steatosis (fat in the liver) via a direct measurement of the hepatic electrical impedance at one or more frequencies. The measurement is taken by means of surface or minimally invasive sensors, which can be coupled to other devices for medical use (e.g., laparoscopic probes). By means of an interpolation algorithm based on correlations between impedance and the percentage of hepatic fat in reference biopsies, the system is capable of determining the degree of hepatic steatosis in the organ measured immediately and without requiring any other kind of intervention. This permits its application to procedures such as liver transplant, allowing a rapid diagnosis of viability to be made, along with other surgical procedures and on explanted organs.
