1. An intraocular micro-display (IOMD) system, comprising:
a head mounted device including:
a camera for capturing a scene image that is forward facing of a user;
a sensor for monitoring an eye of the user and generate gaze direction data; and
a controller communicatively coupled to the camera and the sensor, wherein the controller includes logic that when executed by the controller causes the head mounted device to perform operations including:
acquiring the scene image with the camera;
searching one or more scene images, including the scene image, for a near-vision fiducial that comprises an identifiable visual marker that is worn on or near the user;
adjusting a focal distance of the camera to bring the near-vision fiducial into focus when the near-vision fiducial is identified in the one or more scene images;
determining a gazing direction of the eye based upon the gaze direction data;
identifying a sub-portion of the scene image based upon the gazing direction; and
wirelessly relaying the sub-portion of the scene image to an IOMD implant for display to a retina of the eye.
