First light rays are projected onto and into the cornea, and second light rays, reflected by the cornea, are registered for determining the corneal t
Proposed is a method and a device configuration for determining the corneal thickness of an eye, in particular of a human eye, by means of light rays. First light rays are projected onto and into the cornea, and second light rays, reflected by the cornea, are registered for determining the corneal thickness. A contact element, which is preferably plane-parallel, is placed on the contact area of the cornea, and the first light rays are projected through the contact element onto and into the cornea. The contact element is fixed on the cornea, for example. The first light rays are projected at least in points in a two-dimensional measuring area of the flattened area onto and into the cornea, and the corneal thickness is determined at one or more places of the measuring area.
