Abstract

Knowledge of the anatomical, post-operative position and orientation influences not only the selection of the IOL to be implanted but also the result of the refractive operation on the eye. In the method for selecting an IOL to be implanted into an eye on the basis of the prediction of the anatomical, post-operative position (ALP) and orientation thereof, based on pre-operative measuring values such as, for example, anterior chamber depth (VKT), lens thickness (LD) and axial eye length (AL), the invention additionally or exclusively uses the curvature(s) of the eye lens or measuring values derived therefrom. The proposed method is used to predict the anatomical, post-operative position (ALP) and orientation of an intraocular lens (IOL) to be implanted into an eye.
