NON-CONTACT SYSTEM FOR MEASURING CORNEAL PROPERTIES AND METHOD FOR MEASURING CORNEAL ELASTIC CONSTANT AND VISCOSITY CONSTANT

摘要

A method for measuring corneal elastic constant and viscosity constant comprises steps of: ejecting compressed air toward a cornea of a live eye ball and measuring air pressure thereof; emitting infrared rays during an air ejecting period, for measuring corneal deformation caused by the compressed air applied to the cornea; and calculating an elastic constant and a viscosity constant of the cornea based on Kelvin-Voigt model by utilizing the corneal deformation measured via the infrared rays and the measured air pressure during the air ejecting period. One advantage of the present invention is to aid preliminary detection in eye diseases.
