Abstract
An ophthalmological laser system for photodisruptive irradiation of ocular tissue, including a crystalline lens or a cornea. The system includes an ultra-short pulse laser, the radiation of which is focusable as illumination light via an illumination beam path including a scanner unit and focusing optics. A control unit is programmed to execute determining irradiation control data for photodisruptions at irradiation points in an interior of the ocular tissue distributed three-dimensionally and non-equidistantly to create at least one predetermined target incision. The laser system then irradiates the ocular tissue according to the determined irradiation control data.

An ophthalmological laser system for photodisruptive irradiation of ocular tissue, the ocular tissues including a crystalline lens or a cornea, the ophthalmological laser system comprising:
- an ultra-short pulse laser, the ultra-short pulse laser emitting radiation which is focusable as illumination light via an illumination beam path in an examination region including at least one of the crystalline lens and the cornea, the illumination beam path including a scanner unit and focusing optics;
- a control unit programmed to execute the following:
- determining irradiation control data for photodisruptions at a plurality of irradiation points in the interior of the ocular tissue to create at least one predetermined target incision, wherein the irradiation points are arranged regularly and in such a way that a compensation of a refractive deficit results in the light passing through the ocular tissue;
- and
- controlling a laser to irradiate the ocular tissue according to the determined irradiation control data.
