Biomechanical modelling of the accommodation problem of human eye

Abstract

This paper deals with the biomechanical analyse of the human eye with a complex numerical model. We present our three dimensional finite element model including the built-up parts, applied material and geometric properties. Hereupon we describe the subjects which we want to investigate with this 3D model, such as accommodation, presbyopia and so on. We highlight the accommodation problem of the crystalline lens and its surrounding parts. We discuss and explain the connection between the age-related material properties, geometric and refractive parameters and amplitude of accommodation. The results have shown that beside the geometry and material properties, the refractive attributes might be important too.
