Modelling approaches have been used to complement experimental findings in order to determine how constituents in the accommodative process influence the shape change of the lens. An unexplored factor in modelling is the role of the modelling software on the results of simulated shape change. Finite element models were constructed in both Abaqus and Ansys software using biological parameters from measurements of shape and refractive index of two 35-year-old lenses. The effect of zonular insertion on simulated shape change was tested on both 35-year-old lens models and with both types of software. Comparative analysis of shape change, optical power, and stress distributions showed that lens shape and zonular insertion positions affect the results of simulated shape change and that Abaqus and Ansys show differences in their respective models. The effect of the software package used needs to be taken into account when constructing finite element models and deriving conclusions. info:eu-repo/grantAgreement/EC/H2020/956720/EU/Opto-Biomechanical Eye Research Network/OBERON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 956720-OBERON info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 5.4 2024 ENGINEERING, BIOMEDICAL 26 / 124 = 0.21 2024 Q1 T1 0.767 2024 Biomedical Engineering 2024 Q2 6.3 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Wang, Kehao (orcid)0000-0002-6870-0594 Grasa, Jorge Universidad de Zaragoza Pierscionek, Barbara K. 5004 605 Universidad de Zaragoza Dpto.
