SYSTEM AND METHOD FOR IMPROVING THE ACCOMODATIVE AMPLITUDE AND INCREASING THE REFRACTIVE POWER OF THE HUMAN LENS WITH A LASER

摘要

A system and method for increasing the amplitude of accommodation and/or changing the refractive power of lens material of a natural crystalline lens is provided. Generally, there is provided methods and systems for delivering a laser beam to a lens of an eye in a plurality of patterns results in the increased accommodative amplitude and/or refractive power of the lens. There is further provided a system and method of treating presbyopia by increasing both the flexibility of the human lens and the depth of field of the eye.

1. A method for delivering a laser beam to a lens of an eye in a plurality of patterns comprising:
providing a laser; providing an optical path for directing a laser beam from the laser to the lens of the eye; directing the laser beam in a first pattern on a first portion of the lens of the eye; the first pattern generally following the shape of the outer surface of the lens of the eye; directing the laser beam in a second pattern on a second portion of the lens of the eye; the second pattern having a pattern to cover a specific volume of the second portion of the lens of the eye; the relationship of the first pattern to the second pattern being such that the first pattern is positioned within the lens closer to the lens outer surface than the second pattern; and, both the first and second patterns positioned within the lens of the eye such that they avoid the central portion of the lens of the eye.
