A method and an analysis apparatus for measuring a cornea of an eye includes an ophthalmological analysis system. The ophthalmological analysis system measures a topography of a cornea in a measurement time interval to obtain a number of image data sets of a surface area of the cornea experiencing a change in intraocular pressure. A repeated change in the topography of the cornea is determined from the number of image data sets.

Method and analysis apparatus for measuring a cornea

An ophthalmological analysis system for examining an eye, in particular in the region of a front eye section of an eye includes first and second analysis systems obtaining sectional images of the eye. The first analysis system includes a projection device and a monitoring device arranged relative to each other according to the Scheimpflug rule. The second analysis system is an optical coherence interferometer. A processing device processes a first image data set obtained by the first analysis system and a second image data set obtained by the second analysis system to supplement the first image data set, at least partially, with data of the second image data set.
