Abstract

A method of inserting an intraocular lens into an eye comprises: determining preoperative values of an eye; selecting an intraocular lens based on the preoperative values; inserting the intraocular lens into the eye; determining intraoperative values of the eye; providing an eye model, wherein the eye model includes plural parameters; determining the second value representing a postoperative visual defect of the eye using the eye model, wherein the preoperative values of the eye are assigned to a first subset of the plural parameters of the eye model and wherein the intraoperative values of the eye are assigned to a second subset of the plural parameters of the eye model; and correcting the position and/or the orientation of the inserted intraocular lens or inserting a different intraocular lens based on the value representing the postoperative visual defect of the eye.
