Abstract
A corneal young's modulus algorithm and system using the same is provided, comprising a tonometer and a computation unit. The computation unit comprises an algorithm for calculating young's modulus. The algorithm comprises: (S1) read at least one parameter measured by a tonometer; (S2) apply the at least one parameter and an initial value of Young's modulus to a first equation to obtain an inner deformation amount and an outer deformation amount; (S3) apply the inner deformation amount and the outer deformation amount to a second equation to obtain a calculated deformation amount; (S4) determine if an error value between the calculated deformation amount and the actual deformation amount is minimal; and (S5) obtain Young's modulus.
