Abstract: An ophthalmological device for intracapsular fragmentation of a lens nucleus of an eye comprises a laser source, a focusing optical module, and a scanner system for moving a focus to target locations in the lens nucleus. For the fragmentation of the lens nucleus, an electronic circuit controls the scanner system to move the focus to intracapsular target locations on cutting planes which extend from a posterior surface to an anterior surface of the lens nucleus. The cutting planes form a maximum of two intracapsular intersecting lines on any of the cutting planes. Two of the cutting planes are arranged at a mutual distance larger than a diameter of a phaco handpiece tip and divide the lens nucleus into three fragments.

Abstract: A computer-implemented method and device for characterizing an optical inhomogeneity in a human eye is disclosed, the method comprising: receiving optical coherence tomography data of the eye; receiving image data of an image of the eye recorded by a camera, the image recorded using one or more of the following imaging techniques: direct illumination of the eye, retro-illumination of the eye, or Scheimpflug imaging; and characterizing the optical inhomogeneity as one or more of the following optical inhomogeneity types: a cataract, a floater, or an opacification of the cornea using the optical coherence tomography data and the image data.
