Abstract

This paper deals with the numerical and experimental modeling of a cornea applanation during pressure loading–air puff. The determination of cornea applanation plays a key role in measuring inner eye pressure. A raised level of inner eye pressure is one of the most obvious symptoms of glaucoma. The numerical model for the cornea was established in consideration of its geometrical and physical properties using the finite element method. The primary applanation pressure was determined from obtained numerical results. The experimental model of the cornea was built from silicone. The experimental cornea was subjected to inner pressure that was measured by traditional medical contact and non-contact tonometers applied outside the cornea. Subsequently, the results for this model were used as the referential ones.
