Claims (9)

1 . An intraocular onlay sized and configured for positioning within a capsular bag, comprising: a body comprising an optic portion and feet; the optic portion comprising: an anterior surface and a posterior surface; an annular mask of a selected optical opacity forming a pinhole; and a second optically transparent region exterior to the annular mask; and the feet having a bottom surface that is coplanar with the posterior surface of the optic portion, and the feet are sized and configured in use to be positioned within a capsular bag and to rest with the bottom surface of the feet resting on top of an existing intraocular lens that is located in the capsular bag such that the feet are not anchored to the intraocular lens, wherein the pinhole is an opening in the body extending through the anterior surface and the posterior surface, wherein the feet extend radially away from the annular mask and are sized and configured to extend outside of a periphery of a lens portion of the existing intraocular lens when the bottom surface is resting on top of the existing intraocular lens, wherein the onlay is not secured to the periphery of the lens portion of the existing intraocular lens, allowing the onlay to be moved and the pinhole to be aligned with a visual axis of the eye when the existing intraocular lens is decentered.
2 . The intraocular onlay of claim 1 , wherein the annular mask is less than 100% light-blocking.
3 . The intraocular onlay of claim 1 , further comprising electronics located with the annular mask, the electronics comprising: a sensor to measure a biologic condition; and a transmitter coupled to the sensor to communicate the biologic condition measured by the sensor.
4 . The intraocular onlay of claim 3 , wherein the biologic condition comprises intraocular pressure.
5 . The intraocular onlay of claim 3 , wherein the biologic condition comprises blood glucose.
6 . An apparatus for addressing pseudophakic presbyopia, the apparatus comprising: an intraocular lens (IOL) with a lens portion having a periphery and haptics sized and configured to be positioned in a capsular bag of an eye; and an onlay comprising a body having feet and an optic portion, the optic portion comprising: an anterior surface and a posterior surface; an annular mask of a selected optical opacity forming a pinhole; and a second optically transparent region exterior to the annular mask; wherein the feet have a bottom surface that is planar and the onlay is sized and configured to be positioned with the bottom surface of the feet resting on top of the lens portion of the IOL and under a capsulorhexis edge of the capsular bag with the pinhole aligned on a visual axis of the eye, wherein the bottom surface of the feet is coplanar with the posterior surface of the optic portion and the feet are not secured to the IOL in the capsular bag, wherein the feet extend radially away from the annular mask and are sized and configured to extend outside of the periphery of the lens portion of the IOL when the bottom surface is resting on top of the lens portion of the IOL, wherein the onlay is not secured to the periphery of the lens portion of the IOL, allowing the onlay to be moved and the pinhole to be aligned with the visual axis of the eye when the IOL is decentered.
7 . The apparatus of claim 6 , wherein the pinhole is an opening in the body extending through the anterior surface and the posterior surface.
8 . An intraocular onlay sized and configured for positioning within a capsular bag, comprising: a body comprising an optic portion and feet; the optic portion comprising: an anterior surface and a posterior surface; an annular mask of a selected optical opacity forming a pinhole; and a second optically transparent region exterior to the annular mask; and the feet having a bottom surface that is planar and separated from the posterior surface by a gap, wherein the feet are sized and configured in use to be positioned within a capsular bag and to rest with the bottom surface of the feet resting on top of an existing intraocular lens that is located in the capsular bag whereby the posterior surface is separated from the intraocular lens by the gap, wherein the bottom surface is parallel to the posterior surface, wherein the feet extend radially away from the annular mask and are sized and configured to extend outside of a periphery of a lens portion of the existing intraocular lens when the bottom surface is resting on top of the existing intraocular lens, wherein the onlay is not secured to the periphery of the lens portion of the existing intraocular lens, allowing the onlay to be moved and the pinhole to be aligned with a visual axis of the eye when the existing intraocular lens is decentered.
9 . The intraocular onlay of claim 8 , further comprising electronics located with the annular mask, the electronics comprising: a sensor to measure a biologic condition; and a transmitter coupled to the sensor to communicate the biologic condition measured by the sensor.

Description

TECHNICAL FIELD This disclosure relates in general to the field of ophthalmic lenses, and more particularly, but not by way of limitation, to an onlay for positioning on an intraocular lens to address pseudophakic presbyopia. BACKGROUND This section provides background information to facilitate a better understanding of the various aspects of the disclosure. It should be understood that the statements in this section of this document are to be read in this light, and not as admissions of prior art. Cataract surgery is the most commonly performed surgery in the United States and results with removal of a cataract and implantation of an intraocular lens (IOL). Nearly 3-4 million people a year have cataract surgery every year and this number continues to grow. Once a patient has undergone surgery to remove and replace the cataract with an IOL, they may be left with pseudophakic presbyopia, which is the inability to see up close (near vision) following surgery. Nearly 80% of cataract surgery patients experience this condition. Some patients elect to have an extended depth of focus or multifocal IOL implanted at the time of surgery, but this is an extra expense not covered by insurance and remains a lesser percentage of the total. As it stands now, this is currently the only time the patient has a choice for a presbyopia correcting lens. Once cataract surgery has been performed on both eyes, which usually occurs within two weeks of the first surgery, the window for implantation of an IOL that corrects presbyopia has closed, unless a riskier procedure called an IOL exchange is performed. Many patients that had cataract surgery without a presbyopia correcting IOL later desire to be independent of, or less dependent on, glasses, but this may occur years after cataract surgery. Patients may have more financial resources available at this time than they did at the time of cataract surgery, which prevented those patients from a presbyopia correcting IOL. They also may not have understood what life with a monofocal IOL would entail. Furthermore, their hobbies or interests or occupations may have changed and now more near vision is required for activities of daily life or enjoyment and employment. Currently, there are no FDA approved, non-sulcus, permanent surgical options for pseudophakic patients to improve their near vision without compromising distance vision (as is the case with refractive corneal surgeries). The pinhole intraocular onlay enables pseudophakic patients to have an ultra-thin, new generation, novel intraocular onlay to be placed on top of the existing intraocular lens within the capsular bag and treat presbyopia. SUMMARY An exemplary pinhole intraocular onlay includes a body with an optic portion and feet, the optic portion includes an anterior surface and a posterior surface, an annular mask of a selected optical opacity forming a pinhole, and a second optically transparent region exterior to the annular mask, where the feet extend from the optic portion to be positioned within a capsular bag and rest on top of an existing intraocular lens that is located in the capsular bag. An apparatus for addressing pseudophakic presbyopia including an intraocular lens (IOL) having a lens portion and haptics positioned in a capsular bag of an eye and an onlay having feet and an optic portion, the optic portion including an anterior surface and a posterior surface, an annular mask of a selected optical opacity forming a pinhole, and a second optically transparent region exterior to the annular mask, wherein the feet are positioned on top of the IOL and under a capsulorhexis edge of the capsular bag with the pinhole aligned on a visual axis of the eye.
