Method for the pre-operative selection of an intraocular lens to be implanted in an eye

A method for pre-operative selection of an intraocular lens (IOL) to be implanted in an eye, based on an eye model having the individual biometric parameters of the eye, comprising:

• selecting potentially suitable IOLs using optical parameters thereof including optical power, asphericity, and toricity, and calculating a residual refraction by application of ray tracing for the potentially suitable IOLs,
• using various metrics for calculating the residual refraction and
• for improving the selection, including in the calculation at least one additional parameter that takes into account pre-operative features of the eye, post-operative effects of the selected IOL or surgical technique used.

The method in accordance with 44, wherein post-operative incision-related changes in the cornea are taken into account in that the expected incision-related changes in the cornea are predicted from statistics for post-operative changes determined for a population and included in the calculation for the eye model.
