Abstract

Claims (21)

1 . An implantable artificial capsule, comprising:

a structure comprising an outer, closed perimeter, a central opening, and a continuous groove for accommodating at least a portion of an intraocular lens; and

at least three haptic arms, wherein prior to implantation, at least one haptic arm of said at least three haptic arms is straight and extends at a substantially orthogonal angle from the outer, closed perimeter of the structure,

wherein each haptic arm of said at least three haptic arms comprises only a single trans-scleral anchor for sutureless trans-scleral fixation upon implantation of the implantable artificial capsule in an eye, wherein each of said single trans-scleral anchors is located at a distal end of each of said at least three haptic arms to form a “T” shape.

2 . The implantable artificial capsule of claim 1 , wherein the structure further comprises a lower segment and an upper segment overhanging the lower segment, said lower segment joining said upper segment at a periphery to form said continuous groove of the structure, wherein said at least a portion of the intraocular lens accommodated by the continuous groove accommodates comprises one or more haptics of the intraocular lens.

3 . The implantable artificial capsule of claim 2 , wherein the periphery is rounded.

4 . The implantable artificial capsule of claim 2 , wherein the lower segment is planar.

5 . The implantable artificial capsule of claim 4 , wherein the lower segment supports a second portion of the intraocular lens.

6 . The implantable artificial capsule of claim 2 , wherein the lower segment and the upper segment each have an outer diameter that is about 5 mm to about 10 mm.

7 . The implantable artificial capsule of claim 2 , wherein the central opening of the structure is formed by a first opening through the lower segment and a second opening through the upper segment.

8 . The implantable artificial capsule of claim 7 , wherein the second opening through the upper segment is larger in diameter than the first opening through the lower segment.

9 . The implantable artificial capsule of claim 1 , where the continuous groove is inward-facing.

10 . The implantable artificial capsule of claim 1 , wherein the structure comprises a flexible, biocompatible material.

11 . The implantable artificial capsule of claim 10 , wherein said flexible, biocompatible material comprises at least one of polymethylmethacrylate and acrylic.

12 . The implantable artificial capsule of claim 10 , wherein said flexible, biocompatible material comprises silicone.

13 . The implantable artificial capsule of claim 1 , wherein said structure is opaque or transparent.

14 . The implantable artificial capsule of claim 1 , wherein upon implantation into an eye, said capsule elutes a drug into said eye.

15 . The implantable artificial capsule of claim 1 , wherein the implantable artificial capsule comprises a first haptic arm, a second haptic arm, and a third haptic arm and the outer, closed perimeter of the structure has an outer surface.

16 . The implantable artificial capsule of claim 15 , wherein the first haptic arm begins at a first location along the outer surface of the outer, closed perimeter and ends at a second location opposite the first location of the outer surface, the first haptic arm extending at a substantially orthogonal angle between the first location and the second location,

wherein the second haptic arm begins at a third location along the outer surface of the outer, closed perimeter and ends at a fourth location opposite the third location of the outer surface, the second haptic arm extending at a substantially orthogonal angle between the third location and the fourth location, and

wherein the third haptic arm begins at a fifth location along the outer surface of the outer, closed perimeter and ends at a sixth location opposite the fifth location of the outer surface, the third haptic arm extending at a substantially orthogonal angle between the fifth location and the sixth location.
