CPC A61F 9/008 (2013.01) [A61F 2009/00897 (2013.01); A61F 9/009 (2013.01)] | 16 Claims |
1. An ophthalmic device for treating eye tissue using laser pulses, comprising:
a laser source configured to produce the laser pulses;
an optical focusing unit configured to focus the laser pulses;
a scanning device, with a movable mirror, arranged downstream from the optical focusing unit, and configured to deflect the laser pulses from the optical focusing unit in at least one deflection direction, whereby moving the mirror causes an image field curvature; and
an optical correction element arranged downstream of the scanning device and configured to correct the image field curvature, by imaging, in a focused manner, the laser pulses deflected by the scanning device on an intended treatment area in the eye tissue
wherein the optical focusing unit has a focal length; and
the optical correction element comprises a lens configured to produce a defined displacement or enlargement of the focal length of the optical focusing unit.
|
9. The ophthalmic device of claim 1, further comprising a detection module configured to detect the optical correction element and control a setting of the scanning device depending on a detection of the optical correction element.
|
10. The ophthalmic device of claim 9, wherein the detection module is configured to detect the optical correction element by detecting at least one of: a type of correction element, a position of the correction element, optical properties of the correction element, a thickness of the correction element, or dimensions of the correction element.
