Injectable intraocular implants

1. An intraocular implant injection assembly comprising:

a housing arranged along a longitudinal axis, said housing including a forward portion and a rearward portion;

a syringe, positionable along said longitudinal axis in said rearward portion of said housing;

an intraocular implant positioning subassembly, positioned along said longitudinal axis in said forward portion of said housing;

an intraocular implant mounted in said intraocular implant positioning subassembly; and

an intraocular implant displacer operative to displace said intraocular implant rearwardly along said longitudinal axis relative to said positioning subassembly into said syringe when said positioning subassembly is forwardly displaced relative to said housing by said syringe in response to a user displacing said syringe forwardly within said housing.

2. An intraocular implant injection assembly according to claim 1 and wherein said

syringe comprises a user-sensible azimuthal orientation indicator.

3. An intraocular implant injection assembly according to claim 1 , and wherein said intraocular implant positioning subassembly comprises:

a rearward positioning element including an azimuthal registration aperture; and

a forward positioning element including an azimuthal registration pin operative to engage said azimuthal registration aperture and to prevent relative rotation between said rearward positioning element and said forward positioning element.

4. An intraocular implant injection assembly according to claim 3 and wherein:

said intraocular implant includes haptics; and

a slanted portion of said haptics lies between a forward, inwardly facing, tapered portion of said rearward positioning element and a rearward, outwardly facing, tapered portion of said forward positioning element.

5. An intraocular implant injection assembly according to claim 4 and wherein said tapered portion of said rearward positioning element and said tapered portion of said forward positioning element are configured to guide said haptics while said intraocular implant is loaded into said syringe, thereby maintaining mechanical integrity of said haptics.

6. An intraocular implant injection assembly according to claim 1 and wherein said intraocular implant positioning subassembly includes a plurality of intraocular implant positioning protrusions operative to retain said intraocular implant.

7. An intraocular implant injection assembly according to claim 1 and wherein said intraocular implant positioning subassembly includes an angled shoulder having an angular orientation which is generally identical to that of a forward angled edge of said syringe and which is adapted to engage said forward angled edge.

8. An intraocular implant injection assembly according to claim 1 , wherein:

said intraocular implant includes haptics; and

a forward angled edge of said syringe is configured to allow said haptics to unfold sequentially as said intraocular implant is injected into an eye.

9. An intraocular implant injection assembly according to claim 1 , wherein:

said intraocular implant includes haptics and a capsular body portion; and

said haptics are adapted to urge said capsular body portion away from the cornea when said intraocular implant is implanted in the eye.

10. A system for injecting an intraocular implant into an eye, comprising:

an intraocular implant including haptics and having an optical axis;

an injector having an injector axis, adapted to have said intraocular implant arranged therein such that said optical axis is parallel to said injector axis; and

an intraocular implant displacer operative to inject said intraocular implant into the eye by displacing said intraocular implant along an injection axis which is coaxial with said optical axis.

11. A system according to claim 10 and wherein said injector axis is adapted to have said intraocular implant arranged in said injector such that said injector axis is coaxial with said optical axis.

12. A system for injecting an intraocular implant into an eye according to claim 10 and also comprising an intraocular implant positioning subassembly operative to arrange said intraocular implant in said injector, said intraocular implant positioning subassembly comprising an intraocular implant positioning displacer including a shaft portion operative to push said intraocular implant from said positioning subassembly into said injector.

13. A system for injecting an intraocular implant into an eye according to claim 12 and wherein:

said intraocular implant positioning displacer moves said intraocular implant in a first direction along said injection axis;

said intraocular implant displacer moves said intraocular implant in a second direction along said injection axis; and

said first direction being opposite said second direction.

14. An intraocular implant injection assembly according to claim 1 , wherein:

said intraocular implant includes haptics and a capsular body portion; and

said housing, said syringe and said positioning subassembly are positioned relative to each other such that said displacer is operative to position said intraocular implant in said syringe such that said haptics are folded over said capsular body portion and extend forwardly thereof.

15. An intraocular implant injection assembly according to claim 1 and wherein said rearward portion of said housing comprises a partially bifurcated rear portion.

16. An intraocular implant injection assembly according to claim 1 and wherein said syringe is removable from said housing.

17. An intraocular implant injection assembly according to claim 1 and also comprising a plunger operative to displace said intraocular implant forwardly relative to said syringe.

18. An intraocular implant injection assembly according to claim 1 and wherein:

said intraocular implant includes haptics and a capsular body portion;

said syringe includes an angled forward edge; and

said housing, said syringe and said positioning subassembly are positioned relative to each other such that said displacer is operative to position said intraocular implant in said syringe such that one of said haptics is located adjacent to a shorter side of said syringe at said forward edge.
