Abstract

An intraocular lens system for correcting vision in the eye, including a first lens adapted to be inserted into the eye substantially along the main optical axis and a second lens adapted to be inserted into the eye substantially along the main optical axis, spaced from and in series with the first lens, such that the first and second lenses form a teledioptic lens system.

Claims

1. An intraocular lens implant kit for correcting vision in an eye, comprising:

2. An intraocular lens implant kit according to claim 1, wherein said central portion of said first intraocular lens is a diffractive lens.

3. An intraocular lens implant kit according to claim 1, further comprising

a supplemental lens adapted to be located outside the eye and cooperate with the first and second intraocular lenses.

4. An intraocular lens implant according to claim 3, wherein said supplemental lens is bifocal.

5. An intraocular lens implant kit for correcting vision in an eye having a primary lens in a posterior chamber and an anterior chamber, comprising:

a first intraocular lens adapted to be placed on a surface of said primary lens of said eye, said lens having a peripheral portion and a central portion, said central portion having a negative refractive index, said peripheral portion having refractive powers to correct for refractive errors in the eye; and

a second intraocular lens adapted to be placed in said anterior chamber of said eye, said second intraocular lens having a central portion with a positive refractive index, wherein the first intraocular lens and the second intraocular lens are connected such that natural fluid from the eye can flow between the first intraocular lens and the second intraocular lens.

6. An intraocular lens implant kit according to claim 5, wherein

said primary lens is a natural lens.

7. An intraocular lens implant kit according to claim 5, wherein

said primary lens is an artificial lens.

8. An intraocular lens implant kit according to claim 5, wherein

said central portion of said first intraocular lens is a diffractive lens.

9. An intraocular lens implant kit according to claim 5, wherein

said central portion of said second intraocular lens is a diffractive lens.

10. An intraocular lens implant kit according to claim 5, further comprising

a supplemental lens adapted to be located outside the eye and cooperate with the first and second intraocular lens.

11. An intraocular lens implant kit according to claim 10, wherein said supplemental lens is bifocal.

12. An intraocular lens implant kit according to claim 10, wherein said supplemental lens includes a removable opaque portion.

13. An intraocular lens implant for correcting vision in an eye having an anterior chamber and a posterior chamber, comprising:

a first intraocular lens portion adapted to be implanted in said posterior chamber of an eye;

a second intraocular lens portion adapted to be implanted in said anterior chamber of an eye;

a telescope portion connecting said first intraocular lens portion and said second intraocular lens portion, said telescope portion having a converging lens and a diverging lens aligned along an optical axis, wherein the first intraocular lens and the second intraocular lens are connected such that natural fluid from the eye can flow between the first intraocular lens and the second intraocular lens.

14. An intraocular lens according to claim 13, wherein

said converging and diverging lenses are refractive lenses.

15. An intraocular lens according to claim 13, wherein

said converging and diverging lenses are diffractive lenses.

16. An intraocular lens implant kit according to claim 13, further comprising

a supplemental lens adapted to be located outside the eye.

17. An intraocular lens system for correcting vision in the eye, comprising:

a first lens adapted to be inserted into the eye substantially along the main optical axis; and

a second lens adapted to be inserted into the eye substantially along the main optical axis, spaced from and in series with said first lens, such that said first and second lenses form a teledioptic lens system, wherein the first lens and the second lens are positioned such that natural fluid from the eye can flow between the first lens and the second lens.

18. An intraocular lens system according to claim 17, further comprising

a means for connecting said first and second lenses.

19. An intraocular lens system according to claim 18, wherein

said means for connecting includes at least one strut.

20. An intraocular lens system according to claim 19, wherein

said strut is flexible.

21. An intraocular lens system according to claim 18, further comprising
