Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 an…
