Claim:
1. A method for non-invasively evaluating a cornea of an eye to evaluate a keratoconus disease state, said method comprising: measuring a cardiovascular activity of a person using a cardiovascular analysis system and acquiring a number of measurement data sets of a cardiovascular rate in a measurement time interval; measuring a topography of a cornea and obtaining a number of image data sets of a surface area of the cornea using an ophthalmological analysis system during the measurement time interval when the intraocular pressure of the eye is changing due to the cardiovascular activity; identifying a repetitive change in the topography of the cornea from the number of image data sets, wherein, in each case, the change is measured for points (P) of the surface area of the cornea; and deriving a probability of development of a keratoconus from the repeated change in the topography of the cornea from the acquired data; wherein the repeated change in the topography of the cornea is synchronized with the measurement data of the cardiovascular rate in the measurement time interval.
