METHOD FOR MEASURING AN EYE

A method for measuring the axial length of an eye using optical coherence tomography, during which a plurality of A-scans of the OCT measurement are combined to an axial length, taking into account the alignment with which they were obtained, and taking into account the topography of the cornea.

description A method for measuring the axial length of an eye using optical coherence tomography, during which a plurality of A-scans of the OCT measurement are combined to an axial length, taking into account the alignment with which they were obtained, and taking into account the topography of the cornea. The distance of the front of the cornea from the retina is determined using OCT while measuring or controlling the alignment of the measuring device to the eye in that the topography of the front of the cornea is measured or made available. The calculation of an axial length from an A-scan of the OCT takes into account a corneal topography registered to the A-scans and is the basis for an intraocular lens calculation. The invention exhibits an increased tolerance range with regard to an imprecise alignment of the measuring device to the eye.
