Analysis of cornea curvature using radial basis functions - Part I: Methodology

We discuss the solution of cornea curvature using a meshless method based on radial basis functions (RBFs). A full two –dimensional nonlinear thin membrane partial differential equation (PDE) model is introduced and solved using the multiquadratic (MQ) and inverse multiquadratic (IMQ) RBFs. This new approach does not rely on radial symmetry or other simplifying assumptions in respect of the cornea shape. It also p rovides an alternative to corneal topography modeling methods requiring accurate material parameter values, such as Young's modulus and Poisson ratio, that may not be available.
