METHOD FOR DETERMINING THE TOPOGRAPHY OF THE CORNEA OF AN EYE

摘要

The present invention relates to a method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye according to the invention, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being realized at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration in order to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is necessary to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.
