Abstract

An anterior chamber refractive correction lens (RCL), preferably a custom anterior chamber refractive correction lens (c-RCL) for visual or optical correcting multiple defects or problems of the eye.

Claims

1. An anterior chamber refractive correction lens device configured for implantation through a small incision in the eye, said device comprising:

a deformable lens optic configured to be inserted through the small incision in the eye, said lens optic being a refractive and multifocal lens optic; and

a substantially rigid lens haptic, said lens optic and said lens haptic being configured to be connected together within the anterior chamber of the eye to provide an assembled visually and optically functioning anterior chamber refractive correction lens device, said lens haptic placing said lens optic under slight tension when assembled together to prevent said lens optic from moving relative to said lens haptic and to prevent the inadvertent disconnection of the lens optic from the lens haptic during implantation and use in the eye.

8. A lens according to claim 1, wherein said lens optic is a wavefront lens optic.

20. A lens according to claim 1, wherein said lens optic is also a toric lens optic.

21. A lens according to claim 1, wherein said lens optic is also a wavefront lens optic.

22. A lens according to claim 20, wherein said lens optic is also a wavefront lens optic.

23. A lens according to claim 1, wherein said lens optic is a bifocal lens optic and includes a center circular-shaped multifocal lens surface or zone having and add of +0.5 to +3.0 diopters (D) of approximately 3 millimeters (mm) and an outer concentric ring-shaped multifocal lens surface or zone for early to late presbyopes.

2. An anterior chamber refractive correction lens device configured for implantation through a small incision in the eye, said device comprising:

a deformable anterior chamber lens optic configured to be inserted through the small incision in the eye into the anterior chamber of the eye and fit within the anterior chamber of the eye, said lens optic being a refractive, multifocal and toric lens optic;

an anterior chamber lens haptic configured to be inserted through the small incision in the eye into the anterior chamber of the eye and then fit within the anterior chamber of the eye, said lens haptic being sufficiently stiff and resilient to allow a portion of said haptic portion to be bowed without breaking, said lens haptic configured to connect with said lens haptic at two or more spaced apart locations and place a lens optic portion located between said two or more locations under slight tension while bowing and placing a lens haptic portion of said lens haptic under compression, said lens haptic configured to position and stabilize said lens optic within the anterior chamber of the eye; and

a connection portion located between said lens optic and said lens haptic, said lens optic and said lens haptic being configured to be separately inserted through the small incision in the eye, and then connected together by said connection portion to assemble the anterior chamber refractive correction lens device within the anterior chamber of the eye to then function in unison within the anterior chamber of the eye.

3. A lens according to claim 2, wherein said toric lens optic is defined by a toric lens surface located on one side of said lens optic.

4. A lens according to claim 2, wherein said multifocal lens optic is defined by a multifocal lens surface located on one side of said lens optic.

5. A lens according to claim 2, wherein said a toric lens surface is located on one side of said lens optic and a multi-focal lens surface is located on an opposite side of said lens optic.

6. A lens according to claim 2, wherein said multifocal lens optic is defined by a multifocal lens surface having at least two zones of different lens power.

7. A lens according to claim 6, wherein said multifocal lens surface includes a center circular surface portion and at least one concentric ring surface portion having different lens power.

9. A deformable anterior chamber refractive correction lens device, said device comprising:

a deformable anterior chamber lens optic configured to be inserted through a small incision in the eye into the anterior chamber of the eye and fit within the anterior chamber of the eye, said lens optic being a refractive, wavefront, and multifocal lens optic;

a deformable anterior chamber lens haptic configured to be inserted through a small incision in the eye into the anterior chamber of the eye and fit within the anterior chamber of the eye, said haptic portion configured for positioning said lens optic within the anterior chamber of an eye; and

a connection portion located between said lens optic and said lens haptic, said lens optic and said lens haptic being configured to be separately insert through a small incision in the eye and then connected together by said connection portion to assemble the functioning anterior chamber intraocular lens device.

10. A lens according to claim 9, wherein said wavefront lens optic is defined by a wavefront lens surface located on at least one side of said lens optic.

11. A lens according to claim 9, wherein said multifocal lens optic is defined by a multifocal lens surface provided on at least one side of said lens optic.

12. A lens according to claim 9, wherein said wavefront lens optic is defined by a wavefront lens surface located on one side of said lens optic and said multi-focal lens optic is defined by a multifocal lens surface located on an opposite side of said lens optic.

13. A lens according to claim 9, wherein said multifocal lens optic is defined by a multifocal lens surface having at least two zones of different lens power.

14. A lens according to claim 13, wherein said multifocal lens surface includes a center circular lens surface and at least one concentric ring lens surface having different lens power.

15. A lens according to claim 9, wherein said refractive correction lens includes a least one toric lens surface.

16. A deformable anterior chamber refractive correction lens device, said device comprising:

a deformable anterior chamber lens optic configured to be inserted through a small incision in the eye into the anterior chamber of the eye and fit within the anterior chamber of the eye, said lens optic being a refractive, multifocal, toric, and wavefront lens optic;

a deformable anterior chamber lens haptic configured to be inserted through a small incision in the eye into the anterior chamber of the eye and fit within the anterior chamber of the eye, said lens haptic configured for positioning said lens optic within the anterior chamber of an eye; and

a connection portion located between said lens optic and said lens haptic, said lens optic and said lens haptic being configured to be separately insert through a small incision in the eye and then connected together by said connection portion to assemble the functioning anterior chamber refractive correction lens device.

17. A lens according to claim 16, wherein said multifocal lens optic is defined by a multifocal lens surface provided on at least one side of said lens optic.

18. A lens according to claim 16, wherein said toric lens optic is defined by a toric lens surface provided on at least one side of said lens optic.
