The intraocular pseudophakic contact lens includes a first optical lens and multiple projections extending from the first optical lens. The projections are at least partially coplanar with the first optical lens. The intraocular pseudophakic contact lens also includes multiple anchors partially embedded in or configured to pass through the projections. The anchors are configured to pierce lens material forming a second optical lens of an artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. The anchors extend along an optical axis of the first optical lens. ## Claims ### Claim 1 An apparatus comprising: an intraocular pseudophakic contact lens comprising: a first optical lens; multiple projections extending from sides of the first optical lens, wherein at least one of: (i) an anterior surface of each of the projections is continuous with an anterior surface of the first optical lens and (ii) a posterior surface of each of the projections is continuous with a posterior surface of the first optical lens; and multiple anchors partially embedded in or configured to pass through the projections, the anchors configured to pierce lens material forming a second optical lens of an artificial intraocular lens without entering into predefined openings of the second optical lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens, the anchors extending axially along an optical axis of the first optical lens. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the anchors are configured to couple the intraocular pseudophakic contact lens to different types of artificial intraocular lenses. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising: at least one drug-eluting device located on the intraocular pseudophakic contact lens and configured to deliver at least one medication. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the anchors extend inward from the projections at opposing angles toward the optical axis of the first optical lens. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein portions of the anchors are embedded in the projections. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the projections comprise holes configured to receive the anchors. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the anchors comprise barbed or ribbed pins. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the first optical lens has an uneven weight distribution around the optical axis in order to cause the first optical lens to obtain a specified orientation with respect to the artificial intraocular lens. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the first optical lens is mono-focal or spherical. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the first optical lens is multi-focal or non-spherical. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the first optical lens is configured such that, when the anchors secure the intraocular pseudophakic contact lens to the artificial intraocular lens: a first portion of the posterior surface of the first optical lens contacts the second optical lens; and a second portion of the posterior surface of the first optical lens remains spaced apart from the second optical lens. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein: the anterior surface of each of the projections is continuous with the anterior surface of the first optical lens; and the posterior surface of each of the projections is continuous with the posterior surface of the first optical lens. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein: the first optical lens comprises a central region and one or more annular regions that surround the central region; and different ones of the central and annular regions are configured to provide different refractive powers. ### Claim 14 A system comprising: an intraocular pseudophakic contact lens comprising: a first optical lens; multiple projections extending from sides of the first optical lens, wherein at least one of: (i) an anterior surface of each of the projections is continuous with an anterior surface of the first optical lens and (ii) a posterior surface of each of the projections is continuous with a posterior surface of the first optical lens; and multiple anchors partially embedded in or configured to pass through the projections, the anchors extending axially along an optical axis of the first optical lens; and an artificial intraocular lens comprising a second optical lens, the second optical lens formed of lens material; wherein the anchors are configured to pierce the lens material forming the second optical lens of the artificial intraocular lens without entering into predefined openings of the second optical lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens. ### Claim 15 (depends on 14) The system of claim 14, wherein the artificial intraocular lens is not specifically designed to be coupled to or receive the intraocular pseudophakic contact lens. ### Claim 16 (depends on 14) The system of claim 14, further comprising: at least one drug-eluting device located on the intraocular pseudophakic contact lens and configured to deliver at least one medication. ### Claim 17 (depends on 14) The system of claim 14, wherein the anchors extend inward from the projections at opposing angles toward the optical axis of the first optical lens. ### Claim 18 (depends on 14) The system of claim 14, wherein the intraocular pseudophakic contact lens further comprises alignment markings configured to identify positions for insertion of the anchors into the lens material. ### Claim 19 (depends on 14) The system of claim 14, wherein the first optical lens has an uneven weight distribution around the optical axis in order to cause the first optical lens to obtain a specified orientation with respect to the artificial intraocular lens. ### Claim 20 (depends on 14) The system of claim 14, wherein the first optical lens is configured such that, when the anchors secure the intraocular pseudophakic contact lens to the artificial intraocular lens: a first portion of the posterior surface of the first optical lens contacts the second optical lens; and a second portion of the posterior surface of the first optical lens remains spaced apart from the second optical lens. ### Claim 21 (depends on 14) The system of claim 14, wherein the first optical lens is multi-focal or non-spherical. ### Claim 22 A method comprising: coupling an intraocular pseudophakic contact lens to an artificial intraocular lens; wherein the intraocular pseudophakic contact lens comprises: a first optical lens; multiple projections extending from sides of the first optical lens, wherein at least one of: (i) an anterior surface of each of the projections is continuous with an anterior surface of the first optical lens and (ii) a posterior surface of each of the projections is continuous with a posterior surface of the first optical lens; and multiple anchors partially embedded in or configured to pass through the projections, the anchors configured to pierce lens material forming a second optical lens of the artificial intraocular lens without entering into predefined openings of the second optical lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens, the anchors extending axially along an optical axis of the first optical lens.
