The key element of this innovative measurement method is a soft contact lens with a microfabricated strain gage embedded. allowing the measurement of the cornea curvature deformation due to IOP changes. Tests on a eye-simulating device have shown that the sensor is capable of monitoring continuously a deformation of cornea radius inferior to 0.0055 mm, which corresponds to a sensitivity of better than 2 mmHg IOP, according to an in vitro [2] and an in vivo [3] studies about the correlation between IOP and corneal curvature in human beings.curvaturetext::conference output::conference proceedings::conference paper
