Abstract
A device for ablation processing of ophthalmological implantation material, which is formed by water-containing base material, comprises a laser source, which is configured to generate a pulsed laser beam having a processing wavelength in the ultraviolet wavelength range, wherein the processing wavelength is greater than 193 nm and causes a higher absorptance of the laser beam in the base material of the implantation material than the absorptance of the laser beam in the water of the implantation material is described.

A device for ablation processing of ophthalmological implantation material, which is formed by water-containing base material, comprising:
- a laser source configured to generate a pulsed laser beam having a processing wavelength in the ultraviolet wavelength range, wherein the processing wavelength is greater than 193 nm and causes a higher absorptance of the pulsed laser beam in the base material of the implantation material than absorptance of the laser beam in the water of the implantation material;
- a projection lens configured to radiate the pulsed laser beam onto a surface of the implantation material, and, in a processing region, to trigger an interaction with the implantation material for ablation of the implantation material using laser pulses of the laser beam, wherein the laser pulses have a combination of pulse duration and intensity causing photoablation;
- and
- a scanner device configured to execute a movement of the processing region for the ablation processing according to a processing pattern.
