Intraocular pseudophakic contact lenses and related systems and methods

1. A system comprising:

an intraocular pseudophakic contact lens comprising:

a first optical lens comprising an anterior optical surface and a posterior optical surface, the first optical lens configured to at least partially correct a residual refractive error in an eye;

multiple projections radially extending from the first optical lens; and

multiple anchors axially extending from the projections, the anchors partially embedded in the projections or configured to pass through the projections; and

an artificial intraocular lens comprising a second optical lens, the second optical lens comprising an anterior optical surface and a posterior optical surface and formed of lens material, wherein the residual refractive error comprises a refractive error that exists in the eye after implantation of the artificial intraocular lens in the eye, wherein the artificial intraocular lens is not specifically designed to be coupled to or receive the intraocular pseudophakic contact lens;

wherein the anchors are configured to be inserted through the anterior optical surface of the second optical lens into the lens material in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;

wherein the artificial intraocular lens lacks predefined openings that receive the anchors;

wherein the anchors comprise barbed or ribbed pins configured to pierce the lens material forming the second optical lens of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;

wherein the first optical lens has an uneven weight distribution around a central axis of the first optical lens in order to cause the first optical lens to obtain a specified orientation with respect to the artificial intraocular lens; and

wherein the first optical lens is configured such that, when the anchors secure the intraocular pseudophakic contact lens to the artificial intraocular lens:

an outer portion of the posterior optical surface of the first optical lens contacts the lens material of the second optical lens; and

a remaining portion of the posterior optical surface of the first optical lens remains spaced apart from the anterior optical surface of the second optical lens.

wherein coupling the intraocular pseudophakic contact lens to the artificial intraocular lens comprises inserting the multiple anchors through the anterior optical surface of the second optical lens into the lens material forming the second optical lens of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;

wherein the artificial intraocular lens lacks predefined openings that receive the anchors;

wherein the anchors comprise barbed or ribbed pins configured to pierce the lens material forming the second optical lens of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens;
