1. An intraocular micro-display (IOMD) system, comprising:
a head mounted device including:
a camera that is forward facing of a user;
a controller configured to:
acquire one or more images with the camera, wherein each image of the one or more images is acquired at a corresponding focal distance;
search the one or more images for a near-vision fiducial that includes an identifiable visual marker that is worn on or near the user;
identify a first image of the one or more images as bringing the near-vision fiducial into focus;
adjust a focal distance of the camera to an adjusted focal distance, wherein the adjusted focal distance is associated with the first image;
acquire a second image with the camera having the adjusted focal distance; and
wirelessly relay image data based on the second image to an IOMD implant for display to a retina of an eye of the user.
