  • Publication number: 20180228648
    Abstract: The present invention provides an energized ophthalmic device with an active agent release system and an associated method. The active agent release system can be suitable to dispense an active agent including, for example, a vitamin, lubricant, a saline, a solvent, and/or medicament, at one or more predetermined times, through the use of an energization element contained in the ophthalmic device. The energization element may be a battery and/or an energy receptor antenna. The release of the active agent can be according to a signal received wirelessly, a predetermined time, and/or a sensed condition, which can cause an activation element to conduct a current to at least a portion of a metal cap under stress causing it to fold and thereby expose the active agent to a surrounding environment.
