非接触式角膜特性量测系统以及测得眼角膜之黏滞系数和弹性系数的方法;NON-CONTACT SYSTEM FOR MEASURING CORNEAL PROPERTIES AND METHOD FOR MEASURING CORNEAL ELASTIC CONSTANT AND VISCOSITY CONSTANT

摘要

一种测得眼角膜之黏滞系数和弹性系数的方法，包含：向眼球之角膜喷出压缩空气，并测量其气压值；在进行喷气期间，发射红外线以测量喷到该角膜之空气所造成的角膜变形量；以及依据在该喷气期间所测得之气压值以及由红外线所测得的角膜变形情形，利用凯尔文-福格特模型，计算得出该角膜的黏滞系数和弹性系数。本发明的其中一个优点是可辅助眼睛疾病的初步检测。 A method for measuring corneal elastic constant and viscosity constant comprises: ejecting compressed air toward a cornea of a live eye ball and measuring air pressure thereof； emitting infrared ray during an air ejectingperiod to measure corneal deformation caused by the compressed air applied to the cornea；
