System and method for providing the shaped structural weakening of the human lens with a laser

A system for delivering a laser beam to a lens of an eye in a plurality of sectional patterns comprising:

• a. a laser;
• b. laser focusing optics;
• c. a scanner;
• d. a control system, wherein the control system comprises:
• i. a first predetermined sectional pattern for directing a laser beam on a first portion of the lens of the eye;
• ii. a second predetermined sectional pattern for directing a laser beam on a second portion of the lens of the eye;
• iii. the first predetermined sectional pattern having a pattern that is different from the second sectional pattern, such that the combination and placement of the first and second sectional patterns is designed to result in the shaped structural weakening of the lens.

A method for determining adjustments to refractive errors in the lens of an eye relating to the treatment of presbyopia comprising:

• a. selecting a first shot pattern for the delivery of a laser to the lens of an eye for the purpose of improving accommodative amplitude of the lens;
• b. selecting a second shot pattern for the delivery of a laser to the eye;
• and,
• c. the selection of the second shot pattern being based at least in part upon a change in refractive error as a result of the first shot pattern.

A system for adjusting refractive errors in the lens of an eye relating to the treatment of presbyopia, comprising:

• a. a laser for producing a laser beam;
• b. laser focusing optics;
• c. a scanner;
• and,
• d. a control system, the control system comprising:
• i. a first shot pattern for delivery of a laser to the lens of an eye for the purpose of improving accommodative amplitude of the lens;
• ii. a second shot pattern for delivery of a laser to the eye;
• iii. wherein, the second shot pattern is based at least in part upon a change in refractive error as a result of the first shot pattern.

• ii. a second shot pattern for delivery of a laser to the eye after delivery of the first shot pattern;
• iii. wherein, the second shot pattern is based at least in part upon a observed change in refractive error as a result of the first shot pattern.
