Abstract

This invention describes Ophthalmic Devices with media inserts that have nanostructured Metasurface elements upon or within them. In some embodiments passive ophthalmic devices of various kinds may be formed. Methods and devices for active ophthalmic devices based on Metasurface structures may also be formed.

First claim

The invention claimed is:

1. A method for forming a rigid insert for an ophthalmic device comprising:
depositing nanoscale metallic features onto a substrate to form a metasurface, wherein the nanoscale metallic features have a surface area of less than or equal to 10,000 nm 2 ;
theroforming the substrate with the nanoscale metallic features into a three-dimensional form; and
securing the three-dimensionally thermoformed substrate to an insert to form the rigid insert.

2. The method according to claim 1 additionally comprising:
designing the shapes and sizes of the nanoscale metallic features on a computerized system comprising modeling software.

3. The method according to claim 2 additionally comprising:
placing the rigid insert within a mold;
surrounding the rigid insert with a reactive mixture in the mold; and
polymerizing the reactive mixture to form an ophthalmic device.

4. The method according to claim 3 additionally comprising:
measuring optical characteristics of the ophthalmic device.

5. The method according to claim 4 additionally comprising:
utilizing results obtained from the measuring of the optical characteristics of the ophthalmic device to adjust a design process for the rigid insert.

6. The method according to claim 5 wherein parameters inputted into the modeling software come from ophthalmic measurements performed upon a patient.

7. The method according to claim 1 wherein:
the nanoscale metallic features are arranged in a periodic pattern, the periodic pattern having a periodicity of less than or equal to 700 nm.

8. The method according to claim 7 , wherein the periodic pattern has a periodicity of greater than or equal to 200 nm.

9. The method according to claim 1 , wherein the metasurface is configured to provide vision enhancement to an eye of a patient.

10. The method according to claim 9 , wherein the metasurface alters the optical properties of the rigid insert in a non-radially symmetric manner.

11. A method for forming an opthalmic device utilizing the method according to claim 1 and additionally comprising:
placing the rigid insert within a mold;
surrounding the rigid insert with a reactive mixture in the mold; and
polymerizing the reactive mixture.

12. A method for forming a rigid insert for an opthalmic device comprising:
depositing nanoscale metallic features onto a three-dimensionally thermoformed substrate to form a metasurface, wherein the nanoscale metallic features have a surface area of less than or equal to 10,000 nm 2 ; and
securing the three-dimensionally thermoformed substrate to an insert to form the rigid insert.

13. The method according to claim 12 , wherein the nanoscale metallic features are arranged in a periodic pattern, the periodic pattern having a periodicity of less than or equal to 700 nm.

14. The method according to claim 13 , wherein the periodic pattern has a periodicity greater than or equal to 200 nm.

15. The method according to claim 12 , wherein the metasurface is configured to provide vision enhancement to an eye of a patient.

16. The method according to claim 15 , wherein the metasurface alters the optical properties of the rigid insert in a non-radially symmetric manner.

17. A method for forming an opthalmic device utilizing the method according to claim 12 and additionally comprising:
placing the rigid insert within a mold;
surrounding the rigid insert with a reactive mixture in the mold; and
polymerizing the reactive mixture.
