Intraocular lens system with folding features

1. A method of creating an intraocular lens (IOL) system, comprising:

forming an active lens element to provide dynamic optical power; and

creating mechanical indentations disposed along a perimeter of the active lens element, wherein the mechanical indentations form structurally weakened locations in the active lens element, wherein a first pair of the mechanical indentations define terminal ends of a first folding line extending between the first pair of the mechanical indentations, and wherein the first pair of the mechanical indentations promote folding of the active lens element along the first folding line.

2. The method of claim 1 , wherein creating the mechanical indentations includes at least one of scoring, cutting, marking, perforating, thinning, or weakening the active lens element.

3. The method of claim 1 , wherein creating the first pair of the mechanical indentations includes positioning the first pair of mechanical indentations along the perimeter of the active lens element so that the first folding line symmetrically bisects the active lens element in half.

4. The method of claim 1 , further comprising creating a second pair of the mechanical indentations, wherein a length along the perimeter of the active lens element between all adjacent mechanical indentations is equal.

5. The method of claim 1 , further comprising forming an optical device disposed proximate to a center of the active lens element to provide the dynamic optical power.

6. The method of claim 5 , further comprising forming control circuitry coupled to the optical device to control the dynamic optical power, wherein the optical device includes liquid crystal.

7. The method of claim 1 , wherein forming the active lens element includes forming an encapsulation layer that encapsulates the active lens element by at least one of spray coating or dip coating.

8. The method of claim 7 , wherein the forming the encapsulation layer includes at least one of using silicone, polyethylene, polypropylene, polymethymethacrylate, polyethyleneoxide, or polyvinylalcohol.

9. The method of claim 1 , wherein the mechanical indentations include a plurality of indentation pairs, including the first pair.

10. The method of claim 9 , wherein each of the plurality of indentation pairs are disposed along the perimeter of the active lens element, and wherein each of the mechanical indentations are separated from each other one of the mechanical indentations such that a length along the perimeter of the active lens element between any two adjacent ones of the mechanical indentations is equal.

11. The method of claim 1 , wherein each of the mechanical indentations, including the first pair, are separated from each other one of the mechanical indentations such that a length along the perimeter of the active lens element between any two adjacent ones of the mechanical indentations is equal.

12. The method of claim 1 , wherein at least one of the mechanical indentations is offset from an optical device disposed proximate to a center of the active lens element and extends partially from the perimeter of the active lens element towards the center of the active lens element.

13. The method of claim 12 , wherein a length of the at least one of the mechanical indentations is 45% or less of a radius of the active lens element.

14. The method of claim 12 , wherein a length of the at least one of the mechanical indentations is 5% or less of a radius of the active lens element.

15. The method of claim 1 , wherein at least one of the mechanical indentations does not extend through a thickness of the active lens element.

16. The method of claim 15 , wherein the at least one of the mechanical indentations indents a front side and a back side of the active lens element.
