System and apparatus for treating the lens of an eye
A system and apparatus for increasing the amplitude of accommodation and/or changing the refractive power and/or enabling the removal of the clear or cataractous lens material of a natural crystalline lens is provided. Generally, the system comprises a laser, optics for delivering the laser beam and a control system for delivering the laser beam to the lens in a particular pattern. There is further provided a range determining system for determining the shape and position of the lens with respect to the laser. There is yet further provided a method and system for delivering a laser beam in the lens of the eye in a predetermined shot pattern.
1. A system for determining a position of a lens of an eye, the system comprising:
a laser;
a means to sense a light beam which has passed through at least a portion of the lens of the eye;
laser focusing optics;
a scanner;
a control system;
the control system comprising a means for determining a position of a capsule of the lens based at least in part upon data obtained by the sensing means; and,
a means to provide a 3-dimensional image of the lens of the eye;
wherein the control system comprises a shot pattern for delivering a laser beam from the laser to the lens of the eye.
2. A system for delivering a laser beam to a lens of an eye, the system comprising:
a laser for producing a laser beam;
a scanner;
a focusing optic;
a means for determining a position of the lens;
a means to provide a 3-dimensional image of the lens of the eye; and,
a control system configured to:
direct the laser beam in the lens of the eye in a pattern of shots, the pattern of shots based in part upon a mathematical modeled geometry of a natural human lens; and,
direct the pattern of shots in the lens of the eye based in part upon information provided by the determining means;
wherein the means for determining the position of the lens comprises a range determination system.
3. A system for delivering a laser beam to a lens of an eye, the system comprising:
a laser for producing a laser beam;
a scanner;
a focusing optic;
a means for determining a position of the lens;
a means to provide a 3-dimensional image of the lens of the eye; and,
a control system configured to:
direct the laser beam in the lens of the eye in a pattern of shots, the pattern of shots based in part upon a mathematical modeled geometry of a natural human lens; and,
direct the pattern of shots in the lens of the eye based in part upon information provided by the determining means;
wherein the means for determining the position of the lens is configured to provide data to the control system, wherein the data forms at least in part, a basis to prevent the pattern of shots from being directed to a posterior surface of the lens.
