Prosthetic capsular devices, systems, and methods
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.
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, wherein the anterior opening is surrounded by an anterior wall defining a first capsular-engaging surface;
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 surrounded by a posterior wall defining a second capsular-engaging surface;
a lateral portion interposed between the anterior portion and the posterior portion, wherein the lateral portion protrudes radially beyond the anterior portion and the posterior portion, wherein the lateral portion encloses a lateral side of the housing structure, wherein an internal cavity of the lateral portion forms a groove for containing the intraocular device,
wherein the lateral portion comprises an exterior surface comprising a rounded bulge, the rounded bulge extending radially beyond the anterior portion and the posterior portion,
wherein the lateral portion comprises an interior surface comprising the groove, wherein at least a portion of the interior surface is formed at an acute angle or an obtuse angle relative to the anterior portion and the posterior portion, and
wherein the housing structure is adapted to contain the intraocular device.
2. The prosthetic capsular device of claim 1 , wherein the lateral portion comprises a first straight portion adjacent to the anterior portion and a second straight portion adjacent to the posterior portion.
3. The prosthetic capsular device of claim 2 , wherein the first straight portion extends from the anterior portion, and wherein the second straight portion extends from the posterior portion.
4. The prosthetic capsular device of claim 1 , wherein the housing structure further comprises a central cavity, the central cavity at least partially defined by the anterior wall, the posterior wall, and the lateral portion.
5. The prosthetic capsular device of claim 1 , wherein the intraocular device is capable of being inserted separately from the housing structure into the natural capsular bag without being attached to the housing structure.
6. The prosthetic capsular device of claim 1 , wherein the intraocular device comprises a refractive power between −35D and +35D.
7. The prosthetic capsular device of claim 1 , wherein the intraocular device is affixed to the anterior opening using a friction fit.
8. The prosthetic capsular device of claim 1 , wherein the intraocular device is affixed to the anterior opening using sutures.
9. The prosthetic capsular device of claim 1 , wherein the groove is configured to contain haptics or a capsular tension ring of the intraocular device.
10. 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.
11. 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.
12. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is self-expandable upon insertion in the natural capsular bag.
13. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is deformable for insertion in the natural capsular bag.
14. The prosthetic capsular device of claim 1 , wherein the intraocular device comprises at least one of a Galilean telescope or microscope.
15. The prosthetic capsular device of claim 1 , wherein the intraocular device comprises an electronic accommodating intraocular lens.
16. The prosthetic capsular device of claim 1 , wherein the intraocular device comprises a refractive power of less than −35D.
17. The prosthetic capsular device of claim 1 , wherein the housing structure is symmetrical over a plane at a midpoint of the lateral portion between the anterior portion and the posterior portion.
18. The prosthetic capsular device of claim 1 , wherein the prosthetic capsular device is sized and scaled to accommodate a size of the eye.
19. The prosthetic device of claim 1 , wherein at least one exterior surface of the housing structure comprises a roughened or opacified surface.
