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.

Claims (13)

1. 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;

detecting a position, a geometry, and a structure of the optical element;

determining a basic pattern of the detected geometry of the optical element;

selecting a basic cutting pattern composed of a plurality of planes;

developing a protocol defining a cutting path based on the basic pattern of the detected geometry; and

modifying the optical element using the laser beam according to the protocol.

2. The method as recited in claim 1 , wherein the optical element is a human eye lens.

3. The method as recited in claim 1 , wherein the modifying is performed by surgical cuts.

4. The method as recited in claim 1 , further comprising fragmenting and removing an inner nucleus of the optical element.

5. The method as recited in claim 4 , further comprising filling the inner nucleus with a gel.
