Abstract

A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

Claims

1. A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens, the device comprising:

a housing structure capable of containing an intraocular device, the housing structure comprising;

an anterior portion, wherein the anterior portion comprises an anterior opening, wherein the anterior opening is capable of allowing at least one of insertion, removal, or replacement of the intraocular device, and wherein the anterior opening is further configured to be coupled to a refractive surface to cover the anterior opening;

a posterior portion, wherein the posterior portion comprises a posterior opening wherein the posterior opening is capable of allowing at least one of insertion, removal, or replacement of the intraocular device, and wherein the posterior opening is further configured to be coupled to a refractive surface to cover the posterior opening; and

a continuous lateral portion interposed between the anterior portion and the posterior portion, wherein the continuous lateral portion protrudes radially beyond the anterior portion and the posterior portion, wherein the continuous lateral portion fully encloses a lateral side of the housing structure, wherein an internal cavity of the continuous lateral portion forms a groove for containing the intraocular device,

wherein the housing structure is symmetrical over a plane at a midpoint of the continuous lateral portion between the anterior portion and the posterior portion; and

a refractive surface configured to be attached to at least one of the anterior opening or the posterior opening;

wherein the refractive surface comprises a plurality of tabs for affixing the refractive surface to at least one of the anterior opening or the posterior opening, and wherein the plurality of tabs protrudes from the refractive surface in alternating posterior and anterior directions.

2. The prosthetic capsular device of claim 1, wherein the continuous lateral portion comprises a straight-walled portion, a first curved portion, and a second curved portion.

3. The prosthetic capsular device of claim 2, wherein the straight-walled portion is substantially perpendicular to the anterior opening and the posterior opening.

4. The prosthetic capsular device of claim 2, wherein the first curved portion extends from the anterior portion, and wherein the second curved portion extends from the posterior portion.

5. The prosthetic capsular device of claim 1, wherein the refractive surface is equiconvex.

6. The prosthetic capsular device of claim 1, wherein the tabs are configured to be affixed to the interior of the prosthetic capsular device and the exterior of the prosthetic capsular device in alternating order.

7. The prosthetic capsular device of claim 1, wherein each of the plurality of tabs comprises an eyelet opening for affixing the tab to the prosthetic capsular device or to hold suture for scleral fixation.

8. The prosthetic capsular device of claim 1, wherein the refractive surface is capable of being inserted separately from the housing structure into the natural capsular bag without being attached to the housing structure.

9. The prosthetic capsular device of claim 1, wherein the refractive surface comprises a refractive power between −

35 D and +35 D.

10. The prosthetic capsular device of claim 1, wherein the refractive surface is affixed to at least one of the anterior opening or the posterior opening using a friction fit.

11. The prosthetic capsular device of claim 1, wherein the refractive surface is affixed to at least one of the anterior opening or the posterior opening using sutures.

12. The prosthetic capsular device of claim 1, wherein the refractive surface is usable as a reference point for selection of an intraocular lens for placement in the internal cavity of the continuous lateral portion.

13. The prosthetic capsular device of claim 1, wherein the groove is configured to contain haptics or a capsular tension ring of the intraocular device.

14. The prosthetic capsular device of claim 1, wherein the intraocular device is at least one of an intraocular lens, intraocular pressure sensor, electronic intraocular pressure sensor, photovoltaic cells, solar cells, battery, computer, antennae, sensor, fixation device, capsular tension ring, electronic device, electronic accommodating intraocular lens, liquid crystal display optic, input/output device, or one or more components thereof.

15. The prosthetic capsular device of claim 1, wherein the prosthetic capsular device comprises at least one of silicone, hydrogel, collamer, acrylic, or an acrylic derivative.

16. The prosthetic capsular device of claim 1, wherein the prosthetic capsular device is self-expandable upon insertion in the natural capsular bag.

17. The prosthetic capsular device of claim 1, wherein the prosthetic capsular device is deformable for insertion in the natural capsular bag.

18. The prosthetic capsular device of claim 1, wherein the intraocular device comprises at least one of a Galilean telescope or microscope.

19. The prosthetic capsular device of claim 1, wherein the intraocular device comprises an electronic accommodating intraocular lens.

20. The prosthetic capsular device of claim 1, wherein the refractive surface comprises a refractive power of less than −

35 D.
