...Abhijit Sinha Roy; William J. Dupps, Jr. The purpose of this study is to develop a 3D patient-specific finite element model (FEM) of the cornea and sclera to compare predicted and in vivo refractive outcomes and to estimate the corneal elastic property changes associated with each procedure. Both...

...Ahmed Elsheikh; Daad Alhasso; Aachal Kotecha; David Garway-Heath The ocular response analyzer (ORA) is a new indentation tonometer that subjects the cornea to an increasing then decreasing air pulse, and uses the corresponding two applanation pressures P 1 and P 2 to estimate the intraocular...

...Anna Pandolfi; Gerhard A. Holzapfel Experimental tests on human corneas reveal distinguished reinforcing collagen lamellar structures that may be well described by a structural constitutive model considering distributed collagen fibril orientations along the superior-inferior and the nasal-temporal...

...T. D. Nguyen; R. E. Jones; B. L. Boyce Tensile strip experiments of bovine corneas have shown that the tissue exhibits a nonlinear rate-dependent stress-strain response and a highly nonlinear creep response that depends on the applied hold stress. In this paper, we present a constitutive model...
