    Abstract: The present invention recognizes that lenses, such as contact lenses, can be pigmented using ink that include polymers or polymerizable monomers, preferably the same monomers used to make the lens. The ink can be used to make images on or within the lens. Images made using these inks are preferably digital and can be used in a variety of printing methods, including ink-jet printing.

    Abstract: A contact lens of generally disc-like configuration having a central axis extending through the contact lens and about which the contact lens is substantially symmetric in configuration. The contact lens hasa pupil zone through which the central axis extends and which comprises the area immediately circumferentially surrounding the central axis;an iris zone, which comprises the area circumferentially surrounding the pupil zone; anda peripheral zone which comprises the area circumferentially surrounding the iris zone and extends to the edge of the contact lens.Further in the area immediately adjacent to the periphery of the iris zone and the contact lens and circumferentially extending therearound a band of dark substantially light-absorbing color is provided.

    Abstract: 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, which 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. A second aspect of the present invention is a method of making a medical device that incorporates a drug in at least one coating. A third aspect of the present invention is a method of using a medical device of the present invention to treat or prevent a disease, disorder or condition.
