Abstract: A system includes an ocular device (10) for deployment in or on an eyeball, and an external device (12). The external device has an electrically-actuated energy-transmitting component (16) for mounting in proximity to the eye, and preferably on an external surface of an eyelid of a user so as to move together with the eyelid. Driver circuitry (22) actuates the energy-transmitting component to transfer energy wirelessly to an energy receiver of the ocular device. Some implementations employ near-field resonant coupling between the external device (12) and the ocular device (10), and support data transfer therebetween, optionally via modulation of the transferred power.

Abstract: A device comprising: an elongated head having a distal end formed by an elongated edge of a cutting blade positioned in parallel with an elongated edge of a control blade, wherein the elongated edges of the respective control and cutting blades are separated by a uniform gap forming the distal opening to a channel running from an anterior end to a posterior end of the head, wherein the elongated edge of the cutting blade extends distally beyond the elongated edge of the control blade providing a height differential between the edge of the cutting blade and the edge of the control blade, wherein the edge of the cutting blade is sharp and configured to cut a bodily tissue, and wherein the edge of the control blade is dull and forms a barrier that limits the depth of penetration of the edge of the cutting blade into the bodily tissue.
