Abstract:
The invention relates to a method for determining the location of the ocular pivot point (ADL) in an eye (10) of a test person. In the method, the mean curvature (KH) of the cornea (14) of the eye (10) is determined. The mean phase error (PF) of the eye (10) is determined as is the eye length (LA) from the mean curvature (KH) and the mean phase error (PF). The location of the ocular pivot point (ADL) is determined from the eye length (LA).
