Abstract
The invention concerns an 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, 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, and wherein posterior surfaces of the haptics comprise ridges configured to capture at least one edge of an artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens.
