FIELD: medicine.
SUBSTANCE: system for determining biometric properties of an eye or parts of the eye comprises: OCT device, beam guiding device and control and analysis device. Method for determining biometric properties of an eye or parts of the eye comprises the steps of: emitting a measuring light beam, guiding the measuring light beam towards the eye for a plurality of scans such that for each scan the measuring light beam enters the cornea in a first lateral region, reaches the retina of the eye in a second lateral region including the fovea of the retina along a corresponding beam path, wherein the beam paths are different among each other, interferometrically analyzing the measuring light beam back-reflected from the eye for each scan to provide corresponding OCT data, determining on basis of the OCT data for each scan of the plurality of scans at least one distance from a surface of the retina to a surface of the cornea or to a surface of the lens of the eye; and selecting on basis of the OCT data from the plurality of scans that scan, for which the distance from the surface of the retina to the surface of the cornea or to the surface of the lens is maximum, and outputting the OCT data of the selected scan.
EFFECT: application of this group of inventions will enhance the accuracy of determining biometric properties of the eye.
