Is Cornea Compliant with respect to Age

The goal of this study is to evaluate the structural stiffness of cornea, toward the accurate sensing of the internal eye pressure. For this purpose, we design and develop the eye dynamic sensing system composed of a high-speed camera, and a non-contact tonometer for imparting an air puff to eye. Through experiments, we found an interesting tendency where deformation of central cornea in aged people is more than that in younger people.
