A method for forming an Ophthalmic device insert comprising:
- depositing Nanoscale metallic features on a substrate, wherein the Nanoscale metallic features have a surface area less then or approximately equal to 10,000 nm2;
- forming the substrate with Nanoscale metallic features into a three dimensional form;
- and
- attaching the three dimensionally formed substrate within an insert.
