An ocular prosthesis includes a display device visible at an anterior portion of the ocular prosthesis. The display device is configured to present a changeable image that represents a natural appearance and movement for a visible portion of an eyeball of a subject. A system includes, besides the ocular prosthesis, an implant marker configured to move with an orbital implant disposed in an eye socket of a subject. A method includes determining a change in orientation of an orbital implant in a subject and determining an update to a natural appearance for a visible portion of an eyeball for the subject based on the change in orientation of the orbital implant. The method also includes rendering an update to an image of the natural appearance for a display device disposed in an ocular prosthesis configured to be inserted in the subject anterior to the orbital implant.
