The objective of this study was to evaluate which hyperelastic model could best describe the
non-linear mechanical behavior of the cornea, in order to characterize the capability of the …

Background: Determining the viscoelastic properties of cornea is important in the fields of
understanding of the tissue's response to mechanical actions and the accurate numerical …

The porcine cornea is a standard animal model in ophthalmic research, making its
biomechanical characterization and modeling important to develop novel treatments such as …

Purpose: The aim of this study is to propose a method to construct corneal biomechanical
model which is the foundation for simulation of corneal microsurgery. Methods: Corneal …

This paper presents a simple mechanics model for analyzing the stresses, strains and
displacements of the human cornea under the action of the intraocular pressure. The …

The cornea is a protective transparent connective tissue covering the front of the eye. The
standard uniaxial tensile experiments are among the most popular techniques for …

An analysis of the material properties of porcine corneas has been performed. A simple
stress relaxation test was performed to determine the viscoelastic properties and a …

The cornea is responsible for about seventy percent of refractive power of the eye and
transmits more than ninety percent of the incident light. The refractive power and …

In this work, a hyperelastic model accounting for cross-linking and microstructural damage is
proposed for corneal stroma, where the strengthening mechanisms of the matrix materials …

This work presents a methodology for the in vivo characterization of the complete
biomechanical behavior of the human cornea of each patient. Specifically, the elastic …
