1 . A method of enhancing vision with a laser beam delivery system, the method comprising:
a. delivering a laser beam to an eye of a patient in a laser beam pattern from the laser beam delivery system;
b. the eye comprising a lens and zonules, the lens comprising a lens capsule and lens material within the lens capsule, the eye having a first amplitude of accommodation;
c. delivering the laser beam to the lens of the eye without cutting damaging, or weakening the lens capsule, and without cutting, damaging or weakening an Anterior-Posterior (AP) pillar and an equatorial pillar of the lens material;
d. wherein the laser beam forms a shape changing zone;
e. whereby upon action of the zonules, the shape changing zone moves from a first shape to a second shape increasing the first amplitude of accommodation to a second amplitude of accommodation;
f. wherein the shape changing zone can repeatedly transition from essentially the natural curvature of the lens to a concave shape.
2 . The method of claim 1 , wherein the second amplitude of accommodation is from 0.05 diopters to 5 diopters.
3 . The method of claim 1 , wherein the second amplitude of accommodation is from 1 diopter to 5 diopters.
4 . The method of claim 1 , wherein the second amplitude of accommodation is greater than 2 diopters.
5 . The method of claim 1 , wherein the laser beam is below laser-induced optical breakdown (LIOB) in the lens capsule.
6 . The method of claim 1 , wherein the laser beam never exceeds laser-induced optical breakdown (LIOB) in the lens capsule, the AP pillar and the equatorial pillar.
7 . A method of enhancing the vision of a patient, using a laser beam delivery system, the method comprising:
a. positioning a patient with respect to the laser beam delivery system;
b. the patient having an eye, comprising a lens, a lens capsule and lens material within the lens capsule;
c. delivering the laser beam to the lens of the eye without cutting damaging, or weakening the lens capsule, and without cutting, damaging or weakening an Anterior-Posterior (AP) pillar and an equatorial pillar of the lens material;
d. wherein the laser beam forms a shape changing zone;
e. the shape changing zone capable of movement from a first shape to a second shape, thereby providing an amplitude of accommodation;
f. wherein the shape changing zone can repeatedly transition from essentially the natural curvature of the lens to a concave shape.
8 . The method of claim 7 , wherein the laser beam does not exceed laser-induced optical breakdown (LIOB) in the lens capsule.
9 . The method of claim 7 , wherein the laser beam does not exceed laser-induced optical breakdown (LIOB) in the lens capsule and the AP pillar.
10 . The method of claim 7 , wherein the laser beam does not exceed laser-induced optical breakdown (LIOB) in the lens capsule, the AP pillar and the equatorial pillar.
11 . The methods of claim 7, 8, 9 or 10 , wherein the laser beam delivery pattern comprises an annular ring.
12 . The methods of claim 7, 8, 9 or 10 , wherein the laser beam delivery pattern comprises a first and a second annular ring; wherein the annular rings follow a shape of the lens capsule, and wherein the annular rings do not contact an equatorial axis of the lens.
13 . The methods of claim 7, 8, 9 or 10 , wherein the AP pillar has a cross sectional diameter of about 1 mm to about 2 mm.
14 . The methods of claim 7, 8, 9 or 10 , wherein the AP pillar defines an axis; and the AP pillar axis is coaxial with an AP axis of the eye.
15 . The methods of claim 7, 8, 9 or 10 , wherein the AP pillar defines an axis; and the AP pillar axis is not coaxial with an AP axis of the eye.
16 . The methods of claim 7, 8, 9 or 10 , wherein the AP pillar defines an axis; and the AP pillar axis is not coaxial and is titled with an AP axis of the eye.
17 . The methods of claim 7, 8, 9 or 10 , wherein the laser beam delivery pattern comprises a first and a second annular ring; and wherein the AP pillar defines an axis; and the AP pillar axis is not coaxial with an AP axis of the eye.
18 . The methods of claim 7, 8, 9 or 10 , wherein the laser beam delivery pattern comprises a first and a second annular ring; wherein the annular rings follow a shape of the lens capsule, and wherein the annular rings do not contact an equatorial axis of the lens; and wherein the AP pillar defines an axis; and the AP pillar axis is not coaxial and is titled with an AP axis of the eye.
