Optical modeling and engineering are two research fields that combine many sciences together such as ophthalmology, optometry, physics etc. These fields provide us with knowledge and model eyes that help us simulate different accommodative status. In the XXXII Congress of the European Society of Cataract and Refractive Surgery, September 2014 in London an electronic poster was submitted by Georgios Zoulinakis. In this poster is presented a comparison between three different human model eyes, in different accommodative status, which were designed with and optical design program. There is also a comparison between model eyes that simulate healthy and presbyopic situations. In the results were presented graphs of the MTFs, spot diagrams and diffraction images of a “letter F” in different distances. It was concluded that optical design programs help us to design model eyes that can simulate many different parameters. There is no perfect model until now that can simulate every optical parameter, but the use of each model is specified for different parameters. These models can be configured and used in further research for designing contact and intraocular lenses.
