Methods and apparatus treat the lens capsule so as to increase accommodation of the eye. The treatment of the lens capsule may comprise treating a portion of the lens capsule so as to stiffen the treated portion and improve accommodation of the eye. The intermediate portion of the lens capsule may located between an optically used central portion of the lens capsule and a peripheral portion of the lens capsule connected to zonules of the eye. The stiffened intermediate portion of the lens capsule can improve coupling of the peripheral portion of the lens capsule to the central portion of the lens capsule, such that an amount of accommodation of the optically used central portion of the lens is increased. As the force of the lens capsule to a lens disposed within the lens capsule is increased, the lens may comprise the natural lens of the eye or an artificial lens such as an accommodative IOL. The treatment of the eye to stiffen the intermediate portion may comprise application of one or more of an energy or a substance to the intermediate portion.

1. A method of treating an eye having a lens and a lens capsule, the lens capsule having a central portion, a peripheral portion and an intermediate portion, the peripheral portion connected to zonules of the eye, the intermediate portion corresponding to a location between the peripheral portion and the central portion, the method comprising: treating the intermediate portion of the capsule to stiffen the intermediate portion to increase curvature or movement anteriorly of at least a portion of the lens when the eye accommodates. 2. The method of claim 1, wherein the increased curvature of the lens comprises an increased amount curvature of a natural lens of the eye or an increased amount curvature of an IOL, and wherein the increased movement anteriorly comprises an increased amount of axial movement of the natural lens of the eye or an increased amount of axial movement of the IOL implanted in the eye. 3. The method of claim 1, wherein the intermediate portion is treated to stiffen the intermediate portion without shrinking substantially tissue of the intermediate portion such that far vision of the eye is maintained. 4. The method of claim 1, wherein the intermediate portion is stiffened such that far vision of the eye is maintained to within about 1 D and the an amount of accommodation of the eye is increased by at least about 1 D. 5. The method of claim 1, wherein the intermediate portion of the capsule is treated so as to maintain optical clarity of the intermediate portion when the intermediate portion is stiffened. 6. The method of claim 1, wherein the capsule comprises an anterior capsule and the intermediate portion comprises an intermediate portion of the anterior capsule. 7. The method of claim 6, wherein the lens comprises a natural lens of the eye and wherein the treatment is applied to the intermediate portion of the anterior capsule without penetration of the capsule. 8. The method of claim 7, wherein the central portion of the capsule is coupled to the peripheral portion of the capsule with the stiffened intermediate portion such that the central portion is moved forward when the eye accommodates and the peripheral portion moves inward. 9. The method of claim 8, wherein the central portion of the lens capsule moves anteriorly along an axis of the eye a first amount and the intermediate portion moves anteriorly along the axis a second amount, the first amount greater than the second amount such that the curvature of the central portion is increased when the eye accommodates. 10. The method of claim 1, wherein the capsule comprises a posterior capsule and the intermediate portion comprises an intermediate portion of the posterior capsule. 11. The method of claim 1, wherein treating the intermediate portion comprises delivering one or more of an energy or a substance to the intermediate portion. 12. The method of claim 11, wherein the energy comprises light energy, and wherein the light energy is transmitted through the cornea of the eye and absorbed with the intermediate portion to treat the intermediate portion. 13. The method of claim 11, wherein the one or more of the energy or the substance is delivered to the intermediate portion of the capsule with a probe tip and wherein the probe tip is introduced into an anterior chamber of the eye through an incision in an outer portion of a cornea. 14. The method of claim 1, further comprising performing a capsulorhexis to remove the central portion of the capsule and placing an intraocular lens within the capsule. 15. The method of claim 14, wherein the stiffened intermediate portion decreases radial movement of a capsulorhexis edge such that radially inward force of the peripheral portion is increased by at least about 1 g when the eye accommodates. 16. The method of claim 14, wherein the intermediate portion of the capsule is treated before performing the capsulorhexis to remove the central portion of the capsule, and wherein at least a portion of the stiffened intermediate portion of the capsule remains to move the peripheral portion inward when the eye accommodates with the intraocular lens. 17. The method of claim 14, wherein the stiffened intermediate portion supports the peripheral portion such that the peripheral portion moves the intraocular lens forward with a radially inward force of at least about 3 g. 18. The method of claim 1, further comprising retreating the lens capsule with a second treatment to stiffen the lens capsule at least about one day after the treatment to increase the amount of accommodation of the eye. 19. The method of claim 1, further comprising treating tissue of the lens with a softening treatment located inward of the intermediate portion so as to couple the stiffened intermediate portion of the capsule to the softened tissue to increase the amount of accommodation of the eye. 20. A method of treating an eye having a lens and a lens capsule, the lens capsule having a central portion and a peripheral portion connected to zonules of the eye, the method comprising: applying an adhesive to an intermediate portion of the capsule to stiffen the intermediate portion to increase one or more of curvature or movement of the lens when the eye accommodates, the intermediate portion located between the central portion and the peripheral portion.
