Intraocular lens including scleral engagement portion

1. An intraocular lens comprising:

a lens portion; and

a haptics portion, said haptics portion including a scleral engagement portion including an elongate scleratomy transversing portion and a scleral engagement fixation portion, located at an intermediate location along a length of said elongate scleratomy transversing portion, preventing disengagement of said scleratomy transversing portion from a sclera,

said scleral engagement fixation portion being configured to assume a relatively narrow footprint perpendicular to a central axis thereof during insertion thereof via a scleratomy and a relatively wide footprint perpendicular to said central axis for retaining the scleral engagement fixation portion against passing back through the scleratomy and thus retaining said intraocular lens in position in the eye,

said elongate scleratomy transversing portion comprising a threading portion, extending beyond said scleral engagement fixation portion, which is used for insertion of said intraocular lens and is adapted to be detached from said scleral engagement fixation portion following insertion of said intraocular lens and discarded.

2. An intraocular lens according to claim 1 and wherein said scleral engagement fixation portion is in the form of a button.

3. An intraocular lens according to claim 2 and wherein said button is a multi-lobed button.

4. An intraocular lens according to claim 1 and wherein said scleral engagement fixation portion is in the form of part of a selectably bendable T-shaped element.

5. An intraocular lens according to claim 4 and wherein said T-shaped element includes a flexible base portion.

6. An intraocular lens according to claim 5 and wherein said flexible base portion is formed of suture material.

7. An intraocular lens according to claim 1 and wherein said lens portion and said haptics portion are integrally formed as one piece.

8. An intraocular lens comprising:

a lens portion; and

a haptics portion, said haptics portion including a scleral engagement portion including an elongate scleratomy transversing portion and a scleral engagement fixation portion, located at an intermediate location along a length of said elongate scleratomy transversing portion, preventing disengagement of said scleratomy transversing portion from a sclera,

said scleral engagement fixation portion being configured to be bendable in a first direction along a central axis thereof but not to be bendable in a second direction along said central axis, opposite to said first direction,

said elongate scleratomy transversing portion comprising a threading portion, extending beyond said scleral engagement fixation portion, which is used for insertion of said intraocular lens and is adapted to be detached from said scleral engagement fixation portion following insertion of said intraocular lens and discarded.

9. An intraocular lens according to claim 8 and wherein said scleral engagement fixation portion is configured to assume a relatively narrow footprint perpendicular to a central axis thereof during insertion thereof via a scleratomy and a relatively wide footprint perpendicular to said central axis for retaining the scleral engagement fixation portion against passing back through the scleratomy and thus retaining said intraocular lens in position in the eye.

10. An intraocular lens according to claim 8 and wherein said scleral engagement fixation portion is in the form of a button.

11. An intraocular lens according to claim 10 and wherein said button is a multi-lobed button.

12. An intraocular lens according to claim 8 and wherein said lens portion and said haptics portion are integrally formed as one piece.
