Abstract

Contact lenses incorporate high plus or add power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00 D.

Claims

1. An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression and minimizing halo effect, the ophthalmic lens comprising:

a center zone with a negative power for myopic vision correction; and

at least one treatment zone surrounding the center zone, said at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.0 D.

2. The ophthalmic lens according to claim 1, wherein the at least one treatment zone has a positive power from about +5 D to about +15 D.

3. The ophthalmic lens according to claim 1, wherein a diameter of the center zone is about 3 mm to about 7 mm.

4. The ophthalmic lens according to claim 1, wherein the at least one treatment zone has a power profile that continuously increases from the outer margin of the center zone to the positive power greater than +5.00 D between about 3 mm and about 4.5 mm from a center of the lens.

5. The ophthalmic lens according to claim 1, wherein the at least one treatment zone has a power profile that zig-zags or oscillates.

6. The ophthalmic lens according to claim 1, wherein the at least one treatment zone has an outer margin at about 4.5 mm from a center of the lens.

7. The ophthalmic lens according to claim 1, wherein a halo effect at a black/white edge is minimized.

8. The ophthalmic lens according to claim 1, wherein the ophthalmic lenses comprises a contact lens.

9. The ophthalmic lens according to claim 1, wherein the ophthalmic lenses comprises a spectacle lens.

10. The ophthalmic lens according to claim 1, wherein the ophthalmic lens comprises an intraocular lens, a corneal inlay, or a corneal onlay.

11. The ophthalmic according to claim 1, further comprising one or more stabilization mechanisms.

12. A method for at least one of slowing, retarding or preventing myopia progression by:

providing an the ophthalmic lens having a center zone with a negative power for myopic vision correction and at least one treatment zone surrounding the center zone, said at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00 D; and

altering the growth of the eye.

13. The method according to claim 12, wherein the at least one treatment zone has a positive power from about +5 D to about +15 D.

14. The method according to claim 12, wherein a diameter of the center zone is about 3 mm to about 7 mm.

15. The method according to claim 12, wherein the at least one treatment zone has a power profile that continuously increases from the outer margin of the center zone to the positive power greater than +5.00 D between about 3 mm and about 4.5 mm from a center of the lens.

16. The method according to claim 12, wherein the at least one treatment zone has a power profile that zig-zags or oscillates.

17. The method according to claim 12, wherein the at least one treatment zone has an outer margin between 3.0 mm and 4.5 mm from a center of the lens.

18. The method according to claim 12, wherein a halo effect at a black/white edge is minimized.

19. The method according to claim 12, wherein the ophthalmic lenses comprises a contact lens.

20. The method according to claim 12, wherein the ophthalmic lens comprises an intraocular lens, a corneal inlay, or a corneal onlay.

21. The method according to claim 12, further comprising adding one or more stabilization mechanisms to the lens.

22. An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression, the ophthalmic lens comprising:

a zone with a negative power for myopic vision correction; and

at least one treatment zone, the at least one treatment zone having sufficient area and sufficient power within the area to substantially inhibit progression of myopia.

23. The ophthalmic lens according to claim 22, wherein progression of myopia is less than 50 percent.

24. The ophthalmic lens according to claim 22, wherein power within treatment zone is over +5 D for at least some portion of the treatment zone.

25. The ophthalmic lens according to claim 22, wherein the zone for myopic vision correction is sufficiently large so as to not inhibit satisfactory vision.
