Keywords:Optical measurement, OCT, Contact lens

We have developed an OCT system in which measurement light is incident along the curved surface of a contact lens, and aim to measure the curved surface shape of the lens on the eyeball and its shape change. In this report, we measure and evaluate the curved shape of the lens, and report on the creation of a model eye and the analysis of its radius of curvature.
