Abstract

This invention discloses methods and apparatus for patterning Multi-piece ophthalmic Insert and Ophthalmic lenses comprising Inserts. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel and the lens includes a sealed and encapsulated Multi-piece ophthalmic Insert portion which has been patterned.

First claim

The invention claimed is:

1. A multi-piece insert device for an ophthalmic lens comprising:
a first back curve piece;
a first front curve piece proximate to the first back curve piece such that the first front curve piece registers with the first back curve piece and forms a cavity between the first back curve piece and the first front curve piece;
at least a second back curve piece in contact with the first back curve piece;
a pattern of conductive material within the cavity placed upon one or both of the first front curve piece and the first back curve piece;
at least one electronic component attached to at least a part of the pattern of conductive material; and
a first colorant pattern on a surface of one or both of the first front curve piece and the first back curve piece.

2. The multi-piece insert device of claim 1 , wherein the first colorant pattern is a limbal ring pattern.

3. The multi-piece insert device of claim 2 , wherein the limbal ring pattern comprises a black colorant.

4. The multi-piece insert device of claim 1 , wherein the first colorant pattern is an iris pattern.

5. The multi-piece insert device of claim 1 , wherein the first colorant pattern is a camouflage pattern that obstructs the observance of the electrical component within the multi-piece insert device by changing the appearance of the electrical component.

6. The multi-piece insert device of claim 1 , additionally comprising a first region located within the first colorant pattern that allows visible light to pass through.

7. The multi-piece insert device of claim 6 , additionally comprising a light detector located between the first front curve piece and the first back curve piece and behind the first region.

8. The multi-piece insert device of claim 6 , additionally comprising a second region located within the first colorant pattern comprising a colorant that is opaque to visible light.

9. The multi-piece insert device of claim 8 , additionally comprising an integrated circuit device located between the first front curve piece and the first back curve piece such that at least a portion of the integrated circuit device is behind the second region.

10. The multi-piece insert device of claim 6 , wherein the first region only allows light having certain wavelengths to pass through.

11. An ophthalmic lens device comprising:
a multi-piece insert having at least a first back curve piece, a second back curve piece and a first front curve piece proximate to the first back curve piece such that the first front curve piece registers with the first back curve piece and forms a cavity between the first back curve piece and the first front curve piece;
a conductive material within the cavity placed upon one or both of the first front curve piece and first back curve piece;
at least one electronic component attached to at least part of the conductive material;
an encapsulating layer surrounding the multi-piece insert, wherein the encapsulating layer comprises a hydrogel; and
a first colorant pattern on a surface of the encapsulating layer.

12. The ophthalmic lens device of claim 11 wherein the first colorant pattern is a limbal ring pattern.

13. The ophthalmic lens device of claim 11 , wherein the first colorant pattern is an iris pattern.

14. The ophthalmic lens device of claim 11 , wherein the first colorant pattern is a camouflage pattern that obstructs the observance of the electrical component within the multi-piece insert by changing an appearance of the electrical component.

15. The ophthalmic lens device of claim 11 , additionally comprising a first region located within the first colorant pattern allowing visible light to pass through.

16. The ophthalmic lens device of claim 15 , additionally comprising a light detector located between the first front curve piece and the first back curve piece and behind the first region.

17. The ophthalmic lens device of claim 15 , wherein the first region only allows light having certain wavelengths to pass through.

18. The ophthalmic lens device of claim 16 , additionally comprising a second region located within the first colorant pattern comprising a colorant that is opaque to visible light.

19. The ophthalmic lens device of claim 18 , additionally comprising an integrated circuit device located between the first front curve piece and the first back curve piece such that at least a portion of the integrated circuit device is behind the second region.

20. The ophthalmic lens device of claim 11 , additionally comprising a liquid meniscus lens element.

21. The ophthalmic lens device of claim 11 , additionally comprising a coating over the insert and the first colorant pattern, wherein the coating comprises a more consistent adhesion property than the multi-piece insert and the first colorant pattern without the coating.

22. The ophthalmic lens device of claim 21 , wherein the coating comprises a paralene.

23. The ophthalmic lens device of claim 21 , wherein the coating is applied between the multi-piece insert and the encapsulating layer.
