Claims15
A device for the three-dimensional representation of an operation area during a laser operation, comprising:
- a spatial recording system;
- an image-processing system;
- a spatial display unit wherein the spatial display includes at least one of a 3-D display, a hologram, and a three-dimensional representation unit generated by a laser;
- and
- a simulation unit programmed to realize on the display unit a simulated ablation of an eye from at least one laser firing which is yet to occur.
A method for the three-dimensional representation of an operation area during a laser operation, comprising the steps:
- recording the operation area using a spatial recording system;
- transferring information obtained from the recording to an image-processing system;
- processing the information in an image-processing system;
- and
- representing the processed information three-dimensionally on a spatial display unit;
- realizing on the display unit a simulated ablation of an eye from at least one laser firing which is yet to occur.
A device for the three-dimensional representation of an operation area during a laser operation, comprising:
- a spatial recording system;
- an image-processing system;
- a spatial display unit;
- and
- a simulation unit configured to simulate on the display unit, for each laser firing, a volume removal, wherein the coordinates for the volume removal are measured directly from the scanner on the display.
A device for the three-dimensional representation of an operation area during a laser operation of a cornea, the device comprising:
- a spatial recording system;
- an image-processing system;
- a spatial display unit;
- and
- a simulation unit configured to realize on the display unit, for each laser firing, a simulated ablation that simulates a location and a volume ablation of an actual ablation resulting from the laser firing.
