Abstract
Computational modeling of human eye is crucial in understanding various retinal pathologies such as myopia, retinal schisis, staphylomas, retinal detachment and others. An accurate eye model has many applications in the field of ophthalmology. Myopia is a refractive error of the eye and is characterized by an increase of its axial length. Concepts of mechanics suggest that the sclera of myopic patients deforms more than usual and results in the distension of the eye. The aim of this project is to build a computational model of the human eye using Finite Element Analysis (FEA) and the ABAQUS® software to simulate the eye axial growth for myopic patients. Several models were simulated in order to find the most suitable model for the objectives of the project. The material properties were based on the literature, except for the cornea and sclera that were obtained from an uniaxial experiment and fitted to the Neo-Hookean material model. 1 Using this data, a model with linear and nonlinear materials was built to simulate axial eye growth using appropriate boundary conditions. The stress and strain distributions of the model were similar to those observed in the literature. The model can be used to study the development of myopia due to mechanical loads. This work will primarily contribute to the identification of patients with potential for retinal pathologies and helping physicians to decide when a possible surgery is required.
