Masked intraocular implants and lenses
First Claim
1. A intraocular implant comprising:
- a lens body comprising a lens body material;
a mask with an aperture positioned within the lens body, the mask comprises a plurality of holes that extend between a posterior surface and an anterior surface of the mask; and
a plurality of bridges extending through the holes of the mask from an anterior portion of the lens body disposed on an anterior side of the mask to a posterior portion of the lens body disposed on a posterior side of mask, the bridges being configured to prevent delamination of the lens body from the mask upon compression of the intraocular implant;
wherein the plurality of holes are characterized in that at least one of the hole size, shape, orientation, and spacing of the plurality of holes is varied to reduce the tendency of the holes to produce visible diffraction patterns.

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.
