Medical devices including medicaments and methods of making and using same including enhancing comfort, enhancing drug penetration, and treatment of myopia
The present invention recognizes that medical devices, such as but not limited to contact lenses, can be made having a coating made at least in part using printing technologies to provide drug storage and drug release structures. The coating preferably includes at least one drug reservoir layer and a least one barrier layer, and can include structures, such as but not limited to capillary structures that alone or in combination modulate the release of the drug from the coating. One aspect of the present invention is a medical device that incorporates a drug in at least one coating.

15. The contact lens of claim 12 ,
wherein said subject is a human subject.
16. The contact lens of claim 12 ,
wherein said disease, disorder, or condition that is treated is an inflammation, an allergy, an infection, glaucoma, macular degeneration, a parasite, dry eye, eye discomfort, neovascular Age-Related Macular Degeneration (wet AMD), dry Age-Related Macular Degeneration (dry AMD), diabetic retinopathy, or a combination thereof.
17. The contact lens of claim 1 ,
