The invention relates to a method for performing a movement correction when measuring a human eye, in which the eye is scanned by a measurement beam in order to obtain a set of position values of an eye structure. Scanning extends over a measurement time interval, wherein the position values are each provided with a timestamp within the measurement time interval. A surface shape and a displacement function are determined, with the displacement function representing a movement pattern during the measurement time interval, and the surface shape and the displacement function being determined in such a way that the position values are approximated by the surface shape when the surface shape is moved according to the displacement function. Moreover, the invention relates to an associated measurement system.

Method for performing a movement correction when measuring eyes, and measurement system

In a method for interferometrically capturing measurement points of a region of an eye, a plurality of measurement points are captured by a measurement beam along a trajectory, wherein the same trajectory is passed over by the measurement beam in the region during at least a first iteration and a second iteration. The trajectory of the first iteration is rotated through an angle and/or displaced by a distance in relation to the trajectory of the second iteration in order to obtain a more homogeneous measurement point distribution.
