Abstract
An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens. The haptics are configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet. Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to contact at least one edge of an artificial intraocular lens and capture the artificial intraocular lens between the ridges. The anterior surface of each haptic includes one or more divots or holes.

An apparatus comprising:
- an intraocular pseudophakic contact lens comprising:
- an optical lens;
- and
- haptics extending radially from the optical lens, the haptics configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet;
- wherein anterior surfaces of the haptics comprise textured capsular wall-engaging surfaces configured to contact an inner capsular wall surface at the anterior leaflet, the capsular wall-engaging surfaces configured to promote confinement, capture, or attachment of the haptics;
- wherein posterior surfaces of the haptics comprise ridges configured to contact at least one edge of an artificial intraocular lens and capture the artificial intraocular lens between the ridges to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;
- wherein different portions of the optical lens provide different amounts of magnification;
- wherein the anterior surface of each haptic includes (i) a first surface portion proximate to the optical lens and angled posteriorly with respect to an anterior surface of the optical lens and (ii) a second surface portion distal from the optical lens and angled outwardly with respect to the first surface portion of the haptic;
- and
- wherein the anterior surface of each haptic includes one or more divots or holes, the one or more divots or holes of each haptic sized and configured to receive a portion of a surgical tool in order to facilitate placement of the haptic under the anterior leaflet.

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;
- and
- second haptics extending radially from the second optical lens, the second haptics 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;

- wherein posterior surfaces of the second haptics comprise ridges configured to contact at least one edge of the artificial intraocular lens and capture the artificial intraocular lens between the ridges to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;
- wherein different portions of the second optical lens provide different amounts of magnification;
- wherein the anterior surface of each second haptic includes (i) a first surface portion proximate to the second optical lens and angled posteriorly with respect to an anterior surface of the second optical lens and (ii) a second surface portion distal from the second optical lens and angled outwardly with respect to the first surface portion of the second haptic;
- and
- wherein the anterior surface of each second haptic includes one or more divots or holes, the one or more divots or holes of each second haptic sized and configured to receive a portion of a surgical tool in order to facilitate placement of the second haptic under the anterior leaflet.

- an intraocular pseudophakic contact lens comprising:
- an optical lens;
- and
- at least three haptics extending radially from the optical lens, the haptics configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet;
- wherein anterior surfaces of the haptics comprise textured capsular wall-engaging surfaces configured to contact an inner capsular wall surface at the anterior leaflet, the capsular wall-engaging surfaces configured to promote confinement, capture, or attachment of the haptics;
- wherein posterior surfaces of the haptics comprise ridges configured to contact at least one edge of an artificial intraocular lens and capture the artificial intraocular lens between the ridges to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;
- wherein the anterior surface of each haptic includes (i) a first surface portion proximate to the optical lens and angled posteriorly with respect to an anterior surface of the optical lens and (ii) a second surface portion distal from the optical lens and angled outwardly with respect to the first surface portion of the haptic;
- wherein the anterior surface of each haptic includes one or more divots or holes, the one or more divots or holes of each haptic are configured to receive a portion of a surgical tool in order to facilitate placement of the haptic under the anterior leaflet;
- and
- wherein different portions of the optical lens provide different amounts of magnification such that a first portion of the optical lens provides a specified amount of magnification and a second portion of the optical lens provides less or no magnification relative to the specified amount of magnification.
