Intraocular assembly
An intraocular assembly includes a peripheral side wall ( 12 ) that has a rim ( 16 ) sized to receive therein an intraocular device, and a posterior peripheral edge ( 20 ) that is sharp and extends out from a posteriorly-facing end face ( 22 ) of the side wall. An interior perimeter of the rim is a combination of continuous concave and convex shapes.
1. An intraocular assembly comprising:
a ring sized and shaped to fill a capsular bag of a human eye, said ring having a peripheral side wall that has:
a posterior rim and an anterior rim both extending from an inner perimeter of said peripheral side wall towards a center of said ring, wherein a gap between said posterior rim and said anterior rim is sized to receive therein an intraocular lens, and
two posterior peripheral edges that are sharp and flare out from a posteriorly-facing end face of said side wall, thereby preventing posterior capsule opacification, wherein one of said two posterior peripheral edges flares out from an outermost perimeter of said posteriorly-facing end face of said side wall.
2. The intraocular assembly according to claim 1 , wherein at least one of said posterior and anterior rims is formed with an inner inclined ramp sized to receive therein the intraocular lens, wherein the inclination of said inner inclined ramp is along an anterior-posterior axis of said ring, and wherein rotation of the intraocular lens along said inclined ramp changes an axial position of the intraocular device along an anterior-posterior axis of said ring.
3. The intraocular assembly according to claim 1 , wherein a plurality of apertures are formed in said side wall.
4. The intraocular assembly according to claim 1 , wherein said anterior rim extends anteriorly outwards from the anterior edge of said side wall, and said posterior rim extends radially inward in a posterior direction from the inner perimeter of said side wall.
5. The intraocular assembly according to claim 1 , wherein said posterior rim is radially larger than said anterior rim.
6. The intraocular assembly according to claim 1 , wherein an innermost extremity of said posterior rim is not coplanar with a posteriorly-facing end face of said side wall.
7. The intraocular assembly according to claim 1 , wherein said intraocular assembly is made of colored plastic.
8. The intraocular assembly according to claim 1 , wherein at least one of said posterior and anterior rims comprises an inner rim and an outer rim connected to said inner rim with ribs.
9. The intraocular assembly according to claim 8 , wherein said outer rim is not continuous.
10. The intraocular assembly according to claim 1 , further comprising outer ribs that extend from said peripheral side wall.
11. The intraocular assembly according to claim 1 , wherein said peripheral side wall comprises bendable slats.
12. The intraocular assembly according to claim 3 , wherein any one of said apertures comprises a shutter so that the aperture can be closed or opened.
13. The intraocular assembly according to claim 2 , wherein said inner inclined ramp is saddle-shaped.
14. The intraocular assembly according to claim 2 , wherein said inner inclined ramp is shaped as a screw thread.
15. The intraocular assembly according to claim 1 , further comprising at least one anterior peripheral edge that is sharp and flares out from an anteriorly-facing end face of said side wall, thereby further preventing posterior capsule opacification.
16. The intraocular assembly according to claim 15 , wherein said at least one anterior peripheral edge is two anterior peripheral edges.
17. The intraocular assembly according to claim 2 , wherein said inner inclined ramp comprises a combination of continuous concave and convex shapes.
