Non-invasive sensor for determining functional characteristics of the cornea, device including said sensor and use thereof

摘要

The present invention relates to a sensor and device incorporating said sensor for obtaining data useful to determine the functional characteristics of the cornea in a non-invasive manner, particularly for establishing a correlation between the impedance at different frequencies and the permeability of the endothelium and epithelium and stromal hydration level.

主权项

1. A sensor for measuring impedance comprising n microelectrodes, wherein n is between 4 and 30, arranged on a substrate, the size and arrangement of the microelectrodes being suitable so that the contact a cornea simultaneously, and wherein the microelectrodes are selected for taking measurement in groups of 4 by way of 2 external microelectrodes and 2 internal microelectrodes, wherein the microelectrodes have an elongated shape, so as to have a length and a width, and are arranged in parallel according to their longest side, and wherein the sensor comprises 10 microelectrodes.
