Method and apparatus for non- or minimally disruptive photomanipulation of an eye

A system for treating a person or animal in need of treatment for cataract, pre-cataract or presbyopia by non- or minimally disruptive photomanipulation of the lens of an animal or human eye, comprising:

• a) means for focusing a treatment laser beam into a selected part of the said lens where treatment is intended to occur, said treatment laser beam with wavelength of the light in the range of 700-1000 nm or in the range of 1000-1500 nm;
• b) means for pulsing of said treatment laser beam;
• c) means for measuring one or more types of radiation from the said selected part;
• d) means for processing the said one or more type of radiation from the said selected part;
• e) means for adjusting at least one of the parameters for the said treatment laser beam:
• focus, intensity, wavelength, pulse length, repetition frequency, and pulse train length of said treatment laser beam,
• thereby optimally photobleaching said cataract, pre-cataract or presbyopia and thus treating the disease.

A method for non- or minimally disruptive photomanipulation of the lens and/or its constituents collectively or selectively of an animal or human eye, comprising:

• a) focusing a treatment laser beam into a selected part of the lens and/or its constituents collectively or selectively where treatment is intended to occur;
• b) pulsing of said treatment laser beam;
• c) scanning the treatment laser beam relative to the lens;
• d) measuring one or more types of radiation from the said selected part and utilizing this measurement to decide to stop the said treatment laser beam or to adjust at least one of the parameters:
• focus, intensity, wavelength, pulse length, repetition frequency, and pulse train length of said treatment laser beam and utilizing the measurement to decide to adjust at least one of the parameters:
• scan velocity, size of scanned volume, scan repetitions, and scan pattern.
