Control device for a laser system, laser system, and method for controlling the laser system

A medical laser system comprising:

• a laser;
• and
• a control device configured to arrange and move a focal point of a laser beam of the laser within the lens, wherein the focal point can be moved for at least one cut for the fragmentation or segmentation of the lens into individual fragments or segments and can be moved according to a definable cutting pattern for the fine fragmentation of the lens, determine an individual one of the segments, and move, for the fine fragmentation within the determined segment, the focal point in a radial direction at most up to a distance greater than zero from an edge of the lens according to one of the previous claims, the control device comprising:
• at least one actuator coupled to the laser and configured to move a focal point of a laser beam of the laser by means of the at least one actuator.

A method for controlling a laser system having a laser for introducing cuts into a lens of a human or animal eye, the method comprising:

• a) moving a focal point of a pulsed laser beam of the laser for at least one cut to divide the lens into individual fragments or segments;
• and
• b) moving the focal point according to a definable cutting pattern for the fine fragmentation of the lens;
• wherein for the fine fragmentation within an individual one of the fragments or segments, the focal point is moved in a radial direction at most up to a distance greater than zero from an edge of the lens.

A computer program comprising code including instructions for:

• a) moving a focal point of a pulsed laser beam of the laser for at least one cut to divide the lens into individual fragments or segments;
• and
• b) moving the focal point according to a definable cutting pattern for the fine fragmentation of the lens;
• wherein for the fine fragmentation within an individual one of the fragments or segments, the focal point is moved in a radial direction at most up to a distance greater than zero from an edge of the lens.

A computer-readable storage medium having stored thereon computer executable instructions for:

• a) moving a focal point of a pulsed laser beam of the laser for at least one cut to divide the lens into individual fragments or segments;
• and
• b) moving the focal point according to a definable cutting pattern for the fine fragmentation of the lens;
• wherein for the fine fragmentation within an individual one of the fragments or segments, the focal point is moved in a radial direction at most up to a distance greater than zero from an edge of the lens.
