An ophthalmological system includes an eye tracker and an OCT system. A method of operating this system comprises an ophthalmologic providing data representing a location of a process performed on the eye first B-scans relative to the eye; performing a measurement on the eye with the eye tracker; determining a position of the eye relative to the ophthalmic system based on the measurement by the eye tracker; positioning the eye relative to a reference position of the OCT system based on the provided data and the determined position; performing of A-scans at least three A-scan positions, wherein the at least three A-scan positions do not lie on a common straight line; determining a location of a second B-scans relative to the OCT-system based on the at least three A-scans and / or the provided data so that the second B-scan corresponds to the first B-scan with respect to its position relative to the eye ; and generating a representation of the second B-scans.
