Abstract

A method for selecting an intraocular lens (IOL), to optimize the results of refractive procedures on the eye. According to the invention, the method for selecting the IOL includes: a) determining the required biometrical parameters of the eye; b) using the parameters for a corresponding eye model; c) evaluating, using ray tracing, the data of an IOL to be implanted; d) selecting, on the basis of said data, an IOL to be implanted; and e) repeating the method steps c) and d) for further suitable IOLs. To optimize the method, different measuring methods are used to determine the biometrical parameters, a corresponding patient-specific eye model is identified, and, when selecting the IOL, additional retinal image metrics are taken into consideration alongside the determined data. The method according to the invention permits the optimized selection of a spherical, aspheric, toric or multifocal IOL for implantation.
