a haptic system extending from a single side of the optic and comprising:

(i) a haptic system portion having an annular shape integrated with and affixed to the optic prior to implantation in an eye, wherein the haptic system portion is at least one of (a) embedded into the optic by fusion to the optic, (b) embedded into the optic during fabrication of the optic, or (c) fused to the optic, and

(ii) a plurality of radially disposed closed-loop haptics adapted to move independently in response to forces of at least one of a ciliary muscle or zonules of the eye when implanted and comprising a metallic wire forming each closed loop,

wherein the intraocular lens system disaccommodates under a force of below 1 gram.

2. The intraocular lens system of claim 1 , further comprising:

a geometry restraining member configured to maintain a geometry of the plurality of haptics during a fusion contraction phase after the haptics and the optic are inserted into the eye, and is adapted to be implanted to cooperate with the haptics and the optic,

wherein the optic has an equator and the plurality of closed-loop haptics projects radially outward from the optic, each of the closed loops of the haptics having an equatorial segment and at least one radial segment and having a proximal end and a distal end relative to the optic, the equatorial segments of the closed loops of the plurality of haptics describe an arc defining a circular disc that is configured for being placed such that the disc is coextensive with a capsular bag of the eye and forming spaces between adjacent closed loops of the haptics.

3. The intraocular lens system of claim 2 , wherein each of the haptics comprises a flexible region at the proximal end of the haptic that allows the haptic to move anteriorly and posteriorly relative to the optic.

4. The intraocular lens system of claim 2 , wherein the haptics are angled posteriorly.

5. The intraocular lens system of claim 4 , wherein the haptics are angled at an angle selected from a range of 30 to 45 degrees.

6. The intraocular lens system of claim 2 , wherein the haptics are zonular capture haptics adapted to capture a point of zonular insertion by fusing and becoming integral with an equator of the capsular bag.

7. The intraocular lens system of claim 2 , wherein the haptics are adapted to become two-joint articulated skeletons replacing the capsular bag after the capsular bag is dismantled by radial cuts after the intraocular lens system is inserted into the eye.

8. The intraocular lens system of claim 2 , wherein the geometry restraining member is adapted to maintain a diameter and an angulation of the haptics during the fusion contraction phase.

9. The intraocular lens system of claim 8 , wherein the geometry restraining member comprises at least one arm configured to immobilize the haptic system in a disaccommodated configuration during fusion of the capsular bag.

10. The intraocular lens system of claim 2 , wherein the geometry restraining member is adapted to be sectioned and rendered inoperative at a stage two surgery.

11. The intraocular lens system of claim 2 , wherein the plurality of radially disposed closed-loop haptics comprises four haptics.

12. The intraocular lens system of claim 1 , wherein (a) each closed-loop haptic is affixed to the optic at two points of contact, (b) each closed-loop haptic comprises a maximum width, and (c) the maximum width of each closed-loop haptic is greater than a distance between the two points of contact of the respective closed-loop haptic.

13. The intraocular lens system of claim 12 , wherein the maximum width occurs along a length of an equatorial segment distal from the optic of the respective closed-loop haptic.

14. The intraocular lens system of claim 1 , wherein at least one closed-loop haptic is rectangular or trapezoidal.

15. The intraocular lens system of claim 14 , wherein the at least one closed-loop haptic defines an open interior space to allow fusion of the capsular bag through and around the closed-loop haptic.

16. The intraocular lens system of claim 1 wherein the haptics comprise a nickel titanium alloy and each haptic has a thickness of no more than 0.002 inches.

17. The intraocular lens system of claim 1 , wherein each of the radially disposed haptics is adapted to move independently in response to a force of 0.2 grams.

18. The intraocular lens system of claim 1 , wherein the haptic system comprises an integrated geometry restraining member configured to maintain a geometry of the plurality of haptics during a fusion contraction phase after the haptics and the optic are inserted into the eye, and is adapted to be implanted to cooperate with the haptics and the optic.

19. An intraocular lens system, comprising:

a molded optic; and

a haptic system extending from a single side of the optic and comprising:

(i) a haptic system portion having an annular shape integrated with and affixed to the optic prior to implantation in an eye, wherein the haptic system portion is at least one of (a) embedded into the optic by fusion to the optic, (b) embedded into the optic during fabrication of the optic, or (c) fused to the optic, and

(ii) a plurality of radially disposed closed-loop haptics adapted to move independently in response to forces of at least one of a ciliary muscle or zonules of the eye when implanted and comprising a polymeric suture forming each closed loop,

wherein the intraocular lens system disaccommodates under a force of below 1 gram.
