1. An intraocular device comprising:

  • a single, monofocal lens comprising an optically powered portion, the optically powered portion including a surface with a transition zone, the transition zone configured to reduce a thickness of the lens, measured from an anterior outer surface of the lens to a posterior outer surface of the lens, adjacent to the transition zone in a direction toward an optical axis of a recessed central region of the lens compared to a thickness of the lens, measured from the anterior outer surface of the lens to the posterior outer surface of the lens, adjacent to the transition zone in a direction toward the outer periphery of the lens; and

    a mask configured to block a substantial portion of light from passing through the transition zone so as to block a substantial portion of optical aberrations that would be created by light passing through the transition zone.
