Abstract: The invention relates to a method for monitoring and/or evaluating the topographical positioning of a toric intraocular lens (14) during an operation on a human eye, by means of which the toric intraocular lens (14) is inserted into the human eye and is intended to be brought into its desired end position, the method comprising the following steps: determining at least one axis (7) of an astigmatism to be corrected of a cornea (1) of a human eye, in particular the axis (7) of the plane (2) of incidence of the strongest light refraction and/or the axis of the plane (3) of incidence of the weakest light refraction; and presenting the target axis (18) for the preferred axis (17) of the toric intraocular lens (14) relative to the determined axis (7) of the astigmatism in an electronic display device (19) of an apparatus (21), such that the movable toric intraocular lens (14) can be topographically situated and brought into its desired end position on the basis of the presentation.
