A system for increasing the accommodative amplitude of an eye, the system comprising:

• a. a laser for providing a laser beam;
• b. an optical path for delivery of the laser beam from the laser to a natural crystal lens of an eye;
• c. optics located along the optical path, the optics providing the capability to control the laser beam in the x, y and z directions;
• d. a laser beam delivery pattern, for directing the optics to deliver the laser beam in the laser beam delivery pattern to a predetermined area of the lens of the eye;
