The optical lens is 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 haptics are 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 the artificial intraocular lens. 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 capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. ## Claims ### Claim 1 An apparatus comprising: an intraocular pseudophakic contact lens comprising: an optical lens configured to at least partially correct a residual refractive error in an eye, the residual refractive error comprising a refractive error that exists in the eye after implantation of an artificial intraocular lens in the eye;
