A method for the model-based determination of the biometry of eyes

摘要

The present invention relates to the field of ophthalmology, especially the determination of a plurality of lengths and other factors, on the basis of localized boundary surfaces in the eye.In the case of the method according to the invention for model-based determination of the biometry of eyes, the eye with a light source via a scan - unit is illuminated, the focus of the measuring light beam in the eye by means of an adjusting device laterally and / or axially displaced or changed over and the of the interfaces and out of the fabric of the eye of light scattered back by means of an interferometer is detected by a sensor and to a control - and evaluation unit, which a parametric eyes model, the at least two of the boundary surfaces are present in the eye, adapts to the scan.The present invention relates to the field of ophthalmology and serves, in particular, of the optical determination of the biometry of eyes by means of a two-dimensional, optical coherence tomography images. The method is, however, neither to the use of the coherence tomography still limited to the use of optical measurements.
