Abstract
An ophthalmological analysis instrument includes a first analysis apparatus for measuring a curvature of a cornea of an eye, such as a keratometer or the like, and a second analysis apparatus. The second analysis apparatus includes a projection device and a monitoring device. The projection device includes at least one slit projection unit for projecting a light slit onto a surface of the eye. An image of the light slit is recordable by the monitoring device, the light slit being projectable onto a region of a limbus of the eye by the slit projection unit. A topography of the surface in the region of the limbus is derived from the image of the light slit imaged on the surface.
