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.
