Paper Abstract

With the recent development in the field of micro displays, retinal display and emerging technologies the issue of laser safety of these new devices becomes more and more important. To tackle these problems a lot of basic research will be necessary in order to find appropriate laser safety standards, since the current standards are not fully suitable. In order to avoid animal experiments as far as possible and also aiming for a simulation tool which would assist the manufacturers in their safety considerations, we have developed a thermodynamic model of the whole human eye. Using the software Hypermesh© and Ansys Fluent© we created a Finite-Volume-Method model capable of simulating the behavior of all parts of the eye. I.e. the temperature distribution at any point of the eye can be predicted over time. The model also includes the blood flow within the choroid aiming for a realistic thermal behavior.
