RESUMO
The objective of this study was to obtain a virtual biomechanical three dimensional model of the human eye though a multidisciplinary collaboration between researchers in various medical and informational fields in order to reach a better understanding of the optical performance of the healthy and diseased eye. MATERIAL AND METHOD: In order to obtain the virtual model, we analyzed the CT and MRI images of six patients, aged between 21 and 80 years old, dating from February 2013 until January 2019. These scans totalized 4226 images. We selected to use for the construction of the model the CT images of a male patient of 54 years old. In Vesalius and Geomagic for SolidWorks programs were used. RESULTS: Based on the CT images analysis and using the above mentioned programs, we created a virtual model of the human skull in which the orbit is located, including the eye globe and the extraocular muscles. The SolidWorks virtual model allows the attachment of materials with real properties of the eye tissues. This model can be used in various simulations for the healthy and diseased eye. CONCLUSIONS: The biomechanical eye model of the eye was created based on a "in vivo" eye model. As the SolidWorks format enables using materials with identical properties to those of the human eyeball, this virtual model can provide very realistic eye simulations.
