Abstract

A new approach to measuring intraocular pressure (IOP) and central corneal thickness (CCT) has been developed. This dynamic contact system measures the static stiffness and dynamic modulus (expressed as an amplitude ratio and phase lag) of the eyeball and a dynamic model has been developed which allows separation of the contributions of CCT and IOP. Three different mechanical eyeball configurations have been investigated, simulating different behaviours of a real eyeball. Preliminary results show significant differences in phase lag, dynamic modulus and mean ratio for using different CCT and IOP. © 2009 Springer Berlin Heidelberg.
