Opthalmological therapy system and method for processing a portion of a processing volume of a transparent material by application of focused radiation

An ophthalmologic therapy system for processing portion of a processing volume of a transparent material of an eye by application of focused radiation, comprising

• a device that generates radiation,
• an optical system that focuses the radiation at a focus in the processing volume, wherein the focus of the focused radiation has a focal angle (φ) and the focused radiation has a beam axis,
• a device that changes position of the focus in the processing volume, which can be described with three spatial directions x, y and z, wherein the z-direction proceeds parallel to a base position beam axis of the focused radiation,
• a control device that controls the ophthalmologic therapy system,
• wherein the device for changing the position of the focus comprises a first scanner that is a slow scanner adapted to perform a slow scanning movement three dimensionally in the three spatial directions in the processing volume of the transparent material and a second scanner that is a fast scanner adapted to perform a fast scanning movement three dimensionally in the three spatial directions, and independently from the slow scanning movement of the slow scanner in a section of the processing volume,
• wherein the section of the fast scanning movement is movable by the slow scanning movement in the entire processing volume.
