Abstract
Uniform and location patterned drug release can be achieved via microchannel(s) embedded in a drug dispensing ophthalmic device. At least one reservoir can be encapsulated within the ophthalmic device at a discrete location to hold an amount of a drug. Each reservoir can be covered by an electrode that electrodissolves to release the drug. At least one microchannel having a length and holding at least water is encapsulated in the ophthalmic device between the reservoir and the side of the ophthalmic device facing the eye. After release from the reservoir, the drug spreads through an entirety of the length of the microchannel due to a capillary force inside the microchannel and a diffusion coefficient of the drug in the water. The amount of the drug diffuses from a plurality of locations along the entirety of the length of the microchannel.
