METHOD FOR THE PRE-OPERATIVE SELECTION OF AN INTRAOCULAR LENS TO BE IMPLANTED IN AN EYE

摘要

A method for the preoperative selection of an intraocular lens to optimise the results of refractive surgery on the eye. On the basis of an eye model comprising the individual biometric parameters of the eye, potentially suitable IOLs are selected on the basis of their optical parameters such as optical power, asphericity and toricity, and the residual refraction of potentially suitable IOLs is calculated using ray tracing. Various metrics, preferably retinal image metrics, are used to calculate the residual refraction and in order to improve the selection, at least one additional parameter is taken into consideration for the calculation, said calculation taking the postoperative effects of the selected IOL and/or of the surgical technique used into account.
