Abstract

apparatus comprising: an intraocular pseudophakic contact lens comprising: an optical lens; and haptics extending radially from the optical lens and 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 and secure the intraocular pseudophakic contact lens against an artificial intraocular lens in the eye; wherein anterior surfaces of the haptics comprise 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 capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens; and wherein at least part of the anterior surface of each of the haptics is angled posteriorly with respect to an anterior surface of the optical lens and at least part of the posterior surface of each of the haptics is angled posteriorly with respect to a posterior surface of the optical lens.

18. An apparatus comprising: an intraocular pseudophakic contact lens comprising: an optical lens configured to provide a refractive adjustment in an eye; and at least three haptics extending radially from the 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 haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against an artificial intraocular lens in the eye; wherein anterior surfaces of the haptics comprise 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 and lips projecting inward from the ridges, the ridges and lips 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; wherein each of the haptics comprises an inner portion and an outer portion; wherein the inner portion of each haptic is positioned between the optical lens and the outer portion of the haptic; wherein the inner portion of each haptic projects outward and posteriorly from the optical lens; and wherein, for each haptic, the ridge is defined where a larger thickness of the outer portion of the haptic meets a smaller thickness of the inner portion of the haptic. 1005349388
