Abstract

This invention discloses methods and apparatus for forming Ophthalmic Lenses with Stabilizing Features, and more specifically, Ophthalmic Lenses that include an encapsulated Insert Device.

First claim

What is claimed is:

1. An ophthalmic device with at least one stabilizing feature, the ophthalmic device comprising:
a lens comprising a biocompatible material, wherein the biocompatible material allows for placement of the lens on an eye;
a rigid insert integral with the lens; and
at least one stabilizing feature included within the rigid insert, wherein the stabilizing feature orients the lens when the ophthalmic device is placed on the eye; and
wherein the rigid insert comprises a thermoformed three-dimensional shape.

2. The ophthalmic device of claim 1 , wherein the stabilizing feature alters a front surface topography of the ophthalmic device.

3. The ophthalmic device of claim 1 , wherein the ophthalmic device is formed from polymerizing a reactive monomer mixture into a hydrogel between a front curve mold and a back curve mold.

4. The ophthalmic device of claim 1 , wherein the biocompatible material comprises a polymerized hydrogel.

5. The ophthalmic device of claim 4 , wherein the polymerized hydrogel comprises a silicone.

6. The ophthalmic device of claim 1 , wherein the lens encapsulates the rigid insert.

7. The ophthalmic device of claim 1 , wherein the stabilizing feature comprises a second material different than that of the remainder of the rigid insert.

8. An ophthalmic device with at least one stabilizing feature, the ophthalmic device comprising:
a lens comprising a biocompatible material, wherein the biocompatible material allows for placement of the lens on an eye;
a rigid insert integral with the lens; and
at least one stabilizing feature included within the rigid insert, wherein the stabilizing feature orients the lens when the ophthalmic device is placed on the eye; and
wherein the rigid insert is in direct contact with the atmosphere and a cornea of an eye on respective anterior and posterior surfaces.

9. The ophthalmic device of claim 8 , wherein the at least one stabilizing feature alters a front surface topography of the ophthalmic device.

10. The ophthalmic device of claim 8 , wherein the at least one stabilizing feature comprises a second material different than that of the remainder of the rigid insert.

11. The ophthalmic device of claim 8 , wherein the rigid insert is asymmetrical.

12. The ophthalmic device of claim 8 , wherein the rigid insert comprises zones having different indices of refraction.

13. The ophthalmic device of claim 8 , wherein the rigid insert comprises a thermoformed three-dimensional shape.

14. An ophthalmic device with at least one stabilizing feature, the ophthalmic device comprising:
a lens comprising a biocompatible material, wherein the biocompatible material allows for placement of the lens on an eye;
a rigid insert integral with the lens; and
at least one stabilizing feature included within the rigid insert, wherein the stabilizing feature orients the lens when the ophthalmic device is placed on the eye; and
wherein the rigid insert is asymmetrical.

15. The ophthalmic device of claim 14 , wherein the at least one stabilizing feature alters a front surface topography of the ophthalmic device.

16. The ophthalmic device of claim 14 , wherein the at least one stabilizing feature comprises a second material different than that of the remainder of the rigid insert.

17. The ophthalmic device of claim 14 , wherein the rigid insert is in direct contact with the atmosphere and a cornea of an eye on respective anterior and posterior surfaces.

18. The ophthalmic device of claim 14 , wherein the rigid insert comprises zones having different indices of refraction.

19. The ophthalmic device of claim 14 , wherein the rigid insert comprises a thermoformed three-dimensional shape.

20. An ophthalmic device with at least one stabilizing feature, the ophthalmic device comprising:
a lens comprising a biocompatible material, wherein the biocompatible material allows for placement of the lens on an eye;
a rigid insert integral with the lens; and
at least one stabilizing feature included within the rigid insert, wherein the stabilizing feature orients the lens when the ophthalmic device is placed on the eye; and
wherein the rigid insert comprises zones having different indices of refraction.

21. The ophthalmic device of claim 20 , wherein the zones are tailored to correct for astigmatic characteristics of the eye.

22. The ophthalmic device of claim 21 , wherein the stabilizing feature properly orients the ophthalmic device on the eye by aligning the zones with their corresponding regions of the eye.

23. The ophthalmic device of claim 20 , wherein the at least one stabilizing feature alters a front surface topography of the ophthalmic device.

24. The ophthalmic device of claim 20 , wherein the at least one stabilizing feature comprises a second material different than that of the remainder of the rigid insert.

25. The ophthalmic device of claim 20 , wherein the rigid insert is in direct contact with the atmosphere and a cornea of an eye on respective anterior and posterior surfaces.

26. The ophthalmic device of claim 20 , wherein the rigid insert is asymmetrical.

27. The ophthalmic device of claim 20 , wherein the rigid insert comprises a thermoformed three-dimensional shape.
