A Theoretical Model of the Cornea for Use in Studies of Tonometry.
A presentation of the "sandwich-shell" model of the cornea, which should be sufficiently flexible to contain many parameters of the cornea while remaining amenable to analysis. The author discusses the mechanical properties and typical dimensions of the cornea and the parameters normally used to characterize a shell structure, in order to show that Reissner's sandwich-shell theory can be used to develop a satisfactory model. A set of equilibrium equations based on Reissner's theory is presented. Effects of corneal parameters on the stress resultants due to intraocular pressure are shown by numerical examples. 25 pp. Ref.
