Pinhole intraocular onlay
An 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 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.
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.
