Abstract
A method for detecting structures within an optical element of an eye and processing the optical element as a function of the detected structures includes acquiring, by a detection device, geometric data of an eye, transferring, by the detection device, the geometric data of the eye to a controller, calculating, by the controller, target coordinates for a processing device including a laser, the processing device being connected to the controller, and applying a beam produced by the laser to the eye according to the target coordinates calculated by the controller so as to process the optical element.

A method for performing partial phacoemulsification, the method comprising:
- cutting a complete path along an inner nucleus of a human eye lens;
- reducing, with a laser, the nucleus to fragments using geometric cutting patterns;
- and
- removing the nucleus of the lens using an irrigation device to produce a hollow lens body.
A method for modifying an optical element using a laser beam, the method comprising:
- measuring a dynamic optical wavefront produced by the optical element during accommodation;
- measuring geometric parameters associated with the dynamic optical wavefront;
- planning a fs-laser cutting therapy based upon the measured geometric parameters;
