Project Description

The project deals with the mechanical modelling of accommodation of a human eye. Using clinical and experimental data concerning the behavior of an eye as a background, and combining this with technical shell modelling knowledge, a few basic areas of computational structural modelling are studied. The background knowledge is used to accurately describe the geometry of the lens and its parts, but also to develop relevant and efficient numerical models. The main work in the proposed project will be done in the context of a general mechanical simulation, using non-linear analysis and considering small but finite elastic deformations. Material data of the constituent parts are an important part of work. Aspects of presbyopia and its relation to age will also be considered in the project. Special interest in the simulations will be directed towards the influence of the vitreous and its effects on the force-movement relations in the model. The project will lead to an improved phenomenological understanding of the mechanical behavior of the structure and will give improved knowledge on the process of accommodation. In addition to developing the framework of a general simulation algorithm, the aim is also to give at least some results of clinical interest concerning the process of accommodation in connection to the reversal of presbyopia and the prevention of glaucoma and cataract.
