Abstract
An ophthalmological measuring device for determining geometric structures in an eye includes an optical, triangulating measurement system for determining at least one geometric reference in the eye by triangulation, and an optical, interferometric measurement system for determining geometric detailed structures in the eye by optical interferometry. The measuring device is designed to position the geometric detailed structures determined by the interferometric measurement system on the basis of the at least one geometric reference in the eye determined by the triangulating measurement system. This firstly allows the interferometric measurement system to register geometric detailed structures in the eye with a high optical resolution and at places that are not visible to the triangulating measurement system, and secondly allows the positioning of said geometric detailed structures in the eye on the basis of geometric references that are determined by the triangulating measurement system without significant movement artifacts.
