Abstract

The intraocular implant comprises a lens substrate and a coating layer with an adhesion layer provided therebetween, the adhesion layer comprising a specific compound.

Claims

1. An intraocular implant comprising:

a lens substrate;

a coating layer formed of a first material; and

an adhesion layer disposed between said lens substrate and said coating layer, said adhesion layer comprising a second material different from said first material, said second material having at least one compound selected from the group consisting of;

(a) a hydrocarbon compound;

(b) a halogenated hydrocarbon compound;

(c) a hetero-element-containing hydrocarbon compound;

(d) an organic metal compound; and

(e) an organosilane compound.

2. The intraocular implant according to claim 1, wherein said lens substrate comprises polymethyl methacrylate, hydroxyl methacrylate, a silicone resin, or a polyurethane resin.

3. The intraocular implant according to claim 1, wherein said adhesion layer is a plasma-polymerized film.

4. The intraocular implant according to claim 3, wherein said coating layer is a plasma-polymerized film.

5. The intraocular implant according to claim 3, wherein said coating layer is a vacuum deposition film.

6. The intraocular implant according to claim 1, wherein said coating layer is a hydrophilic coating layer.

7. The intraocular implant according to claim 1, wherein said coating layer is an ultraviolet light screening coating layer.

8. The intraocular implant according to claim 1, wherein said coating layer is an anti-dissolving coating layer.

9. The intraocular implant according to claim 1, wherein said coating layer is a wear resistance ocoating layer.
