In Vivo Aging Evaluation of Cornea Stiffness Focused on Curvature under Air Puff Impartment

Abstract

The accurate measurement of the eye pressure is guaranteed only under the condition that the cornea stiffness is the same for all subjects. Conventional research evaluated the cornea stiffness by corneal displacement under an air puff. However, this displacement is not accurate enough because of the cornea deformation was treated in two dimension. In this paper, we capture the corneal deformation in three dimension under air puff and use the curvature to evaluate the cornea stiffness. Through experiments, we found an interesting tendency by statistical significance where the cornea stiffness is related to age.
