Abstract
An apparatus includes an intraocular pseudophakic contact lens. The intraocular pseudophakic contact lens includes an optical lens configured to at least partially correct a residual refractive error in an eye. The residual refractive error includes a refractive error that exists in the eye after implantation of an artificial intraocular lens in the eye. The intraocular pseudophakic contact lens also includes one or more haptics configured to be inserted under an anterior leaflet of a capsular wall in the eye in order to capture and confine the one or more haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens.
Claims19
A system comprising:
- an artificial intraocular lens comprising a first optical lens and first haptics configured to be implanted within a capsular bag in an eye;
- and
- an intraocular pseudophakic contact lens comprising:
- a second optical lens configured to at least partially correct a residual refractive error in the eye, the residual refractive error comprising a refractive error that exists in the eye after implantation of the artificial intraocular lens in the eye;
- second haptics extending radially from the second optical lens and configured to be inserted under an anterior leaflet of a capsular wall in the eye in order to capture and confine the second haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens;
- and
- multiple segments positioned around the second optical lens, a bottom surface of each of the segments located below a posterior surface of the second optical lens of the intraocular pseudophakic contact lens, wherein the segments are configured to elevate the second optical lens over the artificial intraocular lens;
- wherein anterior surfaces of the second haptics comprise textured capsular wall-engaging surfaces configured to attach the second haptics to an inner capsular wall surface at the anterior leaflet;
- and
- wherein posterior surfaces of the second haptics comprise ridges configured to capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens.

A system comprising:
- an artificial intraocular lens comprising a first optical lens and first haptics configured to position the artificial intraocular lens within a capsular bag in an eye;
- and
- an intraocular pseudophakic contact lens comprising:
- a second optical lens configured to at least partially correct a residual refractive error in the eye, the residual refractive error comprising a refractive error that exists in the eye after implantation of the artificial intraocular lens in the eye;
- second haptics extending radially from the second optical lens and configured to be inserted under an anterior leaflet of a capsular wall in the eye in order to capture and confine the second haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens;
- and
- multiple segments positioned around the second optical lens, a bottom surface of each of the segments located below a posterior surface of the second optical lens of the intraocular pseudophakic contact lens, wherein the segments are configured to elevate the second optical lens over the artificial intraocular lens;
- wherein anterior surfaces of the second haptics comprise textured capsular wall-engaging surfaces configured to attach the second haptics to an inner capsular wall surface at the anterior leaflet;
- and
- wherein posterior surfaces of the second haptics comprise pins extending downward away from the second optical lens, wherein each pin is configured to rest on or pierce the first optical lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens.
