System for treating the human lens with a laser
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.
