Description

This study is aims to treat the false nearsightedness by biofeedback technique. Changes of thickness of eye-lens are applied to the feedback system using Purkinje-Sanson image. This measuremental method is enab1e to measure the lens thickness. We apply the measuring system to the convex lens and swine eye-1ens and get the good relationships between the measured data and the rea1 lens thickness
