Mathematical models for the shape analysis of human crystalline lens

The objective of this paper is to present an analysis of mathematical models of the human crystalline lens. Seven existing models presented in the literature were investigated: conic, figuring conicoid, generalized conic, Hermans conic patch, Kasprzak hyperbolic cosine, Urs 10th-order Fourier series and Giovanzana parametric models. The analyzed models describe the shape for a data set of human crystalline lenses with ages from 6 to 82 years. The results highlight the difficulty and complexity of the task of choosing the most appropriate model for the crystalline lens shape.
