1. An ophthalmic device, comprising:
- an intraocular mask comprising an aperture configured to transmit substantially all visible light along the optical axis of the eye, the aperture configured to switch between a first size and a second size in response to application of an external stimulus; and
wherein the aperture is configured to remain locked into the second size after removal of the external stimulus until another application of the external stimulus, the aperture then returning to the first size.

Abstract
Implantable corneal and intraocular implants such as a mask are provided. The mask can improve the vision of a patient, such as by being configured to increase the depth of focus of an eye of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a transition portion that surrounds at least a portion of the aperture. This portion can be configured to switch from one level of opacity to another level of opacity through the use of a controllably variable absorbance feature such as a switchable photochromic chromophore within a polymer matrix.

22. An intraocular mask, comprising:
-
an aperture configured to transmit substantially all visible light along the optical axis of the eye; a first annular zone surrounding the aperture, the first annular zone configured to switch between a first level of opacity and a second level of opacity in response to application of an external stimulus; wherein the first annular zone is configured to remain locked into the second level of opacity after removal of the external stimulus until another application of the external stimulus, the first annular zone then returning to the first level of opacity; and a second annular zone surrounding the aperture, the second annular zone configured to block transmission of substantially all visible light.
