Abstract: Devices and methods of laser surgery of an eye, especially for refractive surgery, preferably for keratoplasty. The invention includes a planning and control unit, a system for laser surgery of an eye and a planning and control method wherein a device coordinate system of the first laser device and a device coordinate system of the characterization device are coupled using registration and measurement data or model data of the lamella can be unambiguously registered to the device coordinate systems, further by a defined edge geometry of the lamella, an ametropia correction during the generation of the lamella and by taking into account the hydration condition of the lamella, as well as methods for surgery.
