Masked intraocular implants and lenses
First Claim
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.

Abstract
Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

20. An intraocular device comprising:
a monofocal lens comprising a first surface and a second surface, the first surface comprising; a first portion positioned at a central region of the first surface, an annular second portion, and an annular third portion positioned at an outer periphery of the first surface, the annular third portion positioned radially outward from the first portion, wherein an optical axis of the lens passes through the first portion, and the annular second portion extends from the first portion to the annular third portion; a mask positioned between the second surface and the annular second portion of the first surface; and wherein the first surface comprises a single sloped portion such that the first portion is closer to the second surface than the third portion, the single sloped portion being the second portion. - View Dependent Claims (22, 23)
