Finite Element Modeling and Simulating of Accommodating Human Crystalline Lens

Abstract

In this paper an axisymmetrical, linear, finite element model of human crystalline lens and zonules is constructed to simulate the accommodation process of the lens, based on the published experimental data. Some detailed modeling procedure and data processing differ from previous studies. Our results show that the optical power increases when ciliary body moves away from the lens. The outcome of this paper proves that numerical modeling is a useful and effective method in the study of accommodation.

Complexity of crystalline lens wobbling investigated by means of combined mechanical and optical simulations

“…But it needs to be emphasized that development of such an opto-mechanical model was not in the scope of the present study. We decided to adapt the optical model [ 14 ] based on ocular biometry and use it together with the mechanical data found in the literature [ 15 – 23 ]. It was meant to be used simply as an utensil for presentation of the computation methodology.…”
