Abstract

A prosthetic capsular device configured to be inserted in a natural capsular bag of an eye after removal of a lens includes a housing structure capable of containing an intraocular device. The housing structure includes a posterior side, an anterior side opposite the posterior side, lateral sides extending between the posterior side and the anterior side, and a cavity at least partially defined by the posterior side, the anterior side, and the lateral sides. The posterior side includes a refractive surface and an opening radially outward of the refractive surface. The anterior side includes an aperture capable of allowing at least one of insertion, removal, and replacement of an intraocular device. The cavity is capable of containing an intraocular device.

Claims

1. A prosthetic capsular device for insertion into a natural capsular bag of an eye after removal of a cataract to contain at least one of an intraocular lens (IOL) and/or a technology device, the prosthetic capsular device comprising:

a housing structure sized and configured to contain at least one of an intraocular lens (IOL) and/or a technology device, the housing structure having a compatible shape to the shape of a natural capsular bag of an eye and comprising;

a continuous anterior circular wall, the anterior circular wall comprising an anterior central opening capable of allowing at least one of insertion, removal, and/or replacement of one or more of an intraocular lens and/or a technology device and a round lip around the anterior central opening, wherein the anterior central opening is in fluid communication with a natural capsular bag of an eye upon insertion into the natural capsular bag;

a continuous posterior circular wall opposite the anterior circular wall, the posterior circular wall comprising a posterior central opening configured to receive a distinct refractive surface;

a first arc-shaped opening located radially outward of the posterior central opening on the posterior circular wall, wherein the first arc-shaped opening extends through a thickness of the posterior circular wall;

a second arc-shaped opening located radially outward of the posterior central opening on the posterior circular wall, wherein the second arc-shaped opening extends through the thickness of the posterior circular wall;

wherein each of the first and second arc-shaped openings has a width between 0 mm and 2 mm;

wherein the first arc-shaped opening is a mirror image of the second arc-shaped opening along a major axis of the prosthetic capsular device, and wherein the first arc-shaped opening is a mirror image of the second arc-shaped opening along a minor axis of the prosthetic capsular device;

a curvilinear, solid, and discoidal continuous equatorial portion interposed amid the anterior circular wall and the posterior circular wall and defining a natural capsular bag-contacting surface, wherein the anterior circular wall and the posterior circular wall extend to the continuous equatorial portion, wherein the anterior circular wall, posterior circular wall, and continuous equatorial portion are integrally formed as a single-piece structure;

wherein the anterior circular wall, posterior circular wall, and continuous equatorial portion substantially enclose the housing structure except at said anterior central opening and posterior central opening;

a cavity defined by the anterior circular wall, posterior circular wall, and continuous equatorial portion, the cavity capable of containing one or more of an intraocular lens and/or a technology device, wherein the cavity includes an internal lip sized and configured to secure the intraocular lens; and

wherein the anterior central opening comprises a diameter ranging from about 5 mm to about 7 mm;

wherein dimensions of the prosthetic capsular device closely matches dimensions of the natural capsular bag of the eye in which the cataract has been removed;

wherein the housing structure is self-expandable when inserted into the natural capsular bag of the eye; and

a distinct refractive surface configured to be attached to the posterior central opening of the housing structure in the natural capsular bag of the eye after the housing structure is inserted in the eye, wherein the distinct refractive surface substantially encloses the posterior central opening upon securement therein;

wherein the distinct refractive surface comprises a lip configured to prevent the distinct refractive surface from being detached from the posterior central opening.

2. The prosthetic capsular device of claim 1, wherein the distinct refractive surface is removable from the housing structure after being attached to the posterior central opening in the natural capsular bag of the eye.

3. The prosthetic capsular device of claim 1, wherein each of the first and second arc-shaped openings comprises an arc between 30°

and 120°

.

4. The prosthetic capsular device of claim 1, wherein each of the first and second arc-shaped openings comprises a slit.

5. The prosthetic capsular device of claim 1, wherein the housing structure further comprises:

a third arc-shaped opening located radially outward of the anterior central opening on the anterior circular wall, wherein the third arc-shaped opening extends through a thickness of the anterior circular wall.

6. The prosthetic capsular device of claim 5, wherein the housing structure further comprises:

a fourth arc-shaped opening located radially outward of the anterior central opening on the anterior circular wall, wherein the fourth arc-shaped opening extends through the thickness of the anterior circular wall.

7. The prosthetic capsular device of claim 1, wherein the distinct refractive surface has a refractive power between −

35 D and +35 D.

8. The prosthetic capsular device of claim 1, wherein the distinct refractive surface has a refractive power less than −

35 D.

9. The prosthetic capsular device of claim 1, wherein the distinct refractive surface has a refractive power greater than +35 D.

10. The prosthetic capsular device of claim 1, wherein the technology device comprises an intraocular pressure sensor.

11. The prosthetic capsular device of claim 1, wherein the technology device comprises at least one of a computer, virtual reality device, augmented reality device, head-mounted display, device with Wifi and/or internet connectivity, image receiver, game device, projector, GPS device, biometric measurement device, retinal prostheses, camera, e-mail sender, or e-mail receiver.

12. The prosthetic capsular device of claim 1, wherein the housing structure comprises a transparent material.

13. The prosthetic capsular device of claim 1, wherein the prosthetic capsular device is deformable so as to be folded and inserted via an injection system.

14. The prosthetic capsular device of claim 1, wherein the distinct refractive surface in the posterior central opening is an intraocular lens (IOL).

15. The prosthetic capsular device of claim 1, wherein the housing structure comprises at least one of silicone, silicone derivatives, acrylic, acrylic derivatives, collamer, biocompatible methacrylates, biocompatible polymers, olefins, or polyimide.

16. The prosthetic capsular device of claim 1, wherein a distance between the anterior circular wall and the posterior circular wall is between about 1.5 mm and about 5.5 mm.
