Systems and methods for a laser assisted eye treatment
A computer program product for controlling a laser-assisted eye treatment, configured to encode a system controller with a routine for planning the eye treatment, invention further relates to a laser-assisted eye treatment system including a laser treatment unit and a system controller, to a method for generating control data for a laser-assisted eye treatment system, to a planning method for a laser-assisted eye treatment and to an eye treatment method using a laser beam for treating a patient's eye. The invention provides systems and methods for a fast laser-assisted eye treatment of a patient's eye which improve the security and minimize the risk of a non-optimal eye treatment and enable sale eye treatment planning and a shortening of the critical phase of the eye treatment. Encoding a system controller by a routine for planning the eye treatment is strictly based on an anatomy of a patient's eye.
1. A laser-assisted eye treatment system that carries out an eye treatment workflow, the system comprising:
a laser treatment unit with a laser source generating a laser beam;
a focusing optics and a three dimensional focus shifting system;
a system controller, configured to control the laser-assisted eye treatment system;
a predefined virtual model eye representing an ideal anatomical structure stored by the system controller;
wherein the system controller is encoded with a computer program comprising instructions configured to encode the system with a routine, the routine comprising:
prior to a critical phase of the eye treatment, planning the eye treatment strictly in relation to a clinical objective and to the ideal anatomical structure of the predefined virtual model eye;
detecting a real anatomical structure of the patient's eye by imaging the patient's eye by use of a characterization unit; and
remapping and reviewing the planned eye treatment strictly in relation to the detected real anatomical structure of the patient's eye.
2. The laser-assisted eye treatment system according to claim 1 , further comprising a first control panel arranged to display a first graphical user interface provided by the system controller and configured to communicate information required for the eye treatment workflow.
3. The laser-assisted eye treatment system according to claim 2 , further comprising a second control panel arranged to display a second graphical user interface provided by the system controller and configured to communicate a subset of information out of an entire set of information required for the eye treatment workflow.
4. The laser-assisted eye treatment system according to claim 3 , wherein the first graphical user interface of the first control panel the second graphical user interface of the second control panel or both is configured to display composite images.
5. The laser-assisted eye treatment system according to claim 3 , wherein different categories of the composite images are periodically superimposed.
6. The laser-assisted eye treatment system according to claim 1 , wherein the laser source generates a pulsed laser beam.
7. The laser-assisted eye treatment system according to claim 1 , wherein the instructions are further configured to encode the system controller with the routine comprising:
correcting the planning of the eye treatment by secondary effects related to a docking of the patient's eye to the laser-assisted eye treatment system, effects related to an interaction between different treatment patterns, effects related to movements, effects related to individual variance or a combination of the foregoing.
8. The laser-assisted eye treatment system according to claim 1 , the instructions further comprising
a section that stores data on at least an ideal anatomical structure, a section for storing at least a clinical objective;
a section for storing and adapting standard treatment patterns;
a section for treating and storing incoming characterization data for establishing real anatomical structures; and
a section for generating an individual treatment pattern.
9. The laser-assisted eye treatment system according to claim 1 , the instructions further comprising a section for correcting the standard treatment pattern or the individual treatment pattern by secondary effects.
10. The laser-assisted eye treatment system according to claim 1 , further comprising the characterization unit.
11. The laser-assisted eye treatment system according to claim 1 , further wherein an eye treatment workflow is encoded in the system controller comprising:
planning the treatment
defining anatomy of the patient's eye
reviewing the planning
laser treatment according to the planning.
12. The laser-assisted eye treatment system according to claim 1 , further comprising:
a docking unit arranged to establish a defined relationship between the laser-assisted eye treatment system and a patient's eye to be treated; and wherein the eye treatment workflow encoded in the system controller further comprises docking of the patient's eye to the laser-assisted eye treatment system before the defining the anatomy.
13. The laser-assisted eye treatment system according to claim 1 , wherein the system controller comprises predefined settings that are categorized.
14. The laser assisted eye treatment system according to claim 1 , the routine further comprising planning the eye treatment in relation to data acquired on a basis of an external pretreatment characterization of the patient's eye.
