Method of making an ocular implant
A method of making a mask configured to improve the depth of focus of an eye of a patient is provided. A substrate with a mask forming feature is provided. The mask forming feature comprises a forming surface that extends from an outer periphery. The forming surface is centered on a central axis of the mask forming feature. A release layer is formed on the forming surface. A mask layer is formed such that the release layer is between the mask layer and the substrate. The mask layer is formed of a biocompatible metal. A surface of the mask layer opposite the release layer is configured to not corrode. The mask layer is separated from the substrate.
1 . A mask configured to improve the depth of focus in an eye of a patient comprising:
a posterior layer formed of a biocompatible metal; and
a cosmetic layer.
2 . The mask of claim 1 , wherein the cosmetic layer is a non-reflective layer
3 . The mask of claim 2 , wherein the cosmetic layer darkens the appearance of the mask.
4 . The mask of claim 1 , wherein the biocompatible metal is a noble metal and the cosmetic layer comprises a carbon layer.
5 . The mask of claim 1 , wherein the biocompatible metal comprises a titanium alloy.
6 . The mask of claim 5 , wherein the titanium alloy exhibits super-elastic characteristics.
7 . The mask of claim 5 , wherein the titanium alloy is nitinol.
8 . The mask of claim 5 , wherein the titanium alloy comprises nickel and titanium.
9 . The mask of claim 5 , wherein the posterior layer is a first layer, and the cosmetic layer is formed of a material that does not react chemically with the titanium alloy.
10 . The mask of claim 9 , wherein the cosmetic layer comprises titanium oxide.
11 . The mask of claim 9 , wherein the cosmetic layer comprises silicon carbide.
12 . The mask of claim 1 , wherein the posterior layer is formed of a biocompatible metal that does not corrode when implanted in the body.
13 . The mask of claim 1 , wherein the posterior layer comprises gold.
14 . The mask of claim 1 , wherein the posterior layer comprises palladium.
15 . The mask of claim 1 , wherein the posterior layer comprises platinum.
16 . The mask of claim 1 , wherein the posterior layer tantalum.
17 . The mask of claim 1 , wherein the posterior layer comprises titanium.
