Abstract

This invention discloses methods and apparatus for providing a biomedical device, such as an ophthalmic lens with an energy receptor capable of powering a processing device.

Claims

1. A method of forming a soft contact lens, the method comprising:

depositing an energy receptor capable of receiving energy via a radio wave on to one of;

a first mold part and a second mold part, wherein together, said first mold part and said second mold comprise a polyolefin and form a mold system for forming the contact lens, and wherein the energy received via a radio wave is suitable for operating a processing device;

prior to the step of depositing a reactive monomer mixture into one of;

the first mold part and the second mold part, depositing a binder layer onto one of the first mold part and the second mold part;

placing the energy receptor onto the binder layer, thereby binding the energy receptor to the binder layer

depositing a reactive monomer mix into to one of;

the first mold part and the second mold part, wherein said reactive monomer mix comprises a silicone-containing component;

positioning the first mold part proximate to the second mold part thereby forming a lens cavity with the energy receptor and at least some of reactive monomer mix in the lens cavity;

exposing the reactive monomer mix to actinic radiation and

placing a processor onto the binder layer, wherein the energy receptor is separate from the processor.

2. The method of claim 1 wherein the energy receptor comprises a metallic wire.

3. The method of claim 2 wherein the wire is positioned proximate to a circumference of the ophthalmic lens outside of a field of vision when the ophthalmic lens is placed on an eye.

4. The method of claim 1 wherein the energy receptor comprises conductive fibers.

5. The method of claim 4 wherein the conductive fibers comprise carbon nanotubes.

6. The method of claim 4 wherein the conductive fibers comprise nanostructures.

7. The method of claim 1 wherein the binder layer comprises a pigment.

8. The method of claim 1 wherein the binder layer comprises a prepolymer.

9. The method of claim 1 wherein the binder layer comprises reactive monomer mix.

10. The method of claim 1 additionally comprising the step of placing a processor onto the binder layer, wherein the energy receptor is separate from the processor and the processor is capable of manipulating information.

11. The method of claim 10, wherein the processor is in electrical communication with the energy receptor.

12. The method of claim 11 wherein the silicone-containing component comprises at least one —

Si—

O—

unit and the total Si and attached O are present in the silicone-containing component in an amount greater than about 20 weight percent.
