Abstract

The present disclosure relates to ophthalmic devices such as ophthalmic lenses. An ophthalmic device may comprise an ophthalmic lens for at least one of slowing, retarding or preventing myopia progression. The ophthalmic lens may comprise 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 comprising an ADD power, the at least one treatment zone having a surface shape comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone.

Claims (23)

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

a center zone with a negative power for myopic vision correction, the center zone having a principal axis orthogonal to a surface thereof and passing through a center of the ophthalmic lens; and

at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile comprising a positive power relative to the center zone, the at least one treatment zone having a surface shape projecting outwardly from a front surface of said ophthalmic lens and comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone, and wherein the at least one treatment zone has a tilt angle between +0.035 and +0.3215 degrees relative to a zero-angle comparator, wherein the tilt angle is designated as zero when a central ray passing through a mid-annulus of the treatment zone passes through an intersection point of a retinal plane of a wearer of the ophthalmic lens and the principal axis, wherein a positive tilt angle causes the central ray passing through the mid-annulus of the treatment zone to intersect the principal axis anterior to the retinal plane, and wherein the at least one treatment zone has an annular configuration sharing the principal axis with the center zone.

2 . The ophthalmic lens according to claim 1 , wherein the tilt angle is configured to direct the central ray passing through the mid-annulus of the treatment zone to cross the principal axis at a point between the retinal plane and a point on the principal axis that represents a coincident point focus of the treatment zone.

3 . The ophthalmic lens of claim 1 , wherein the portion of the generally toroidal shape may be derived from a torus (e.g., a spheroidal torus), after making a slice in the shape of the surface of a right circular cone through the surface of the spheroidal torus wherein the principal axis of the cone is coincident with the axis of rotation about which the torus is generated.

4 . The ophthalmic lens according to claim 1 , further comprising a transition zone disposed between then center zone and the at least one treatment zone such that the at least one treatment zone, the transition zone, and the center zone form a continuous surface.

5 . The ophthalmic lens according to claim 1 , wherein the at least one treatment zone comprises an ADD power relative to myopia correction power of greater than +5.00 D.

6 . The ophthalmic lens according to claim 1 , wherein the at least one treatment zone comprises an optical power from about −10.00 D to about +15.00 D.

7 . The ophthalmic lens according to claim 6 , wherein the tilt angle is dependent upon the optical power of the treatment zone.

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

9 . 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.

10 . The ophthalmic lens according to claim 1 , wherein a halo effect is minimized.

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

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

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

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

15 . The ophthalmic lens according to claim 1 , wherein a negative tilt angle causes the central ray passing through the mid-annulus of the treatment zone to intersect the principal axis posterior to the retinal plane.

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

a center zone with a negative power for myopic vision correction, the center zone having a principal axis orthogonal to a surface thereof and passing through a center of the ophthalmic lens; and

at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile comprising a positive power relative to the center zone, the at least one treatment zone having a surface shape projecting outwardly from a front surface of said ophthalmic lens and comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone, and wherein the at least one treatment zone has a tilt angle between +0.035 and +0.3215 degrees relative to a zero-angle comparator, wherein the tilt angle is designated as zero when a central ray passing through a mid-annulus of the treatment zone passes through an intersection point of a retinal plane of a wearer of the ophthalmic lens and the principal axis, and wherein a positive tilt angle causes the central ray passing through the mid-annulus of the treatment zone to intersect the principal axis anterior to the retinal plane, wherein the at least one treatment zone exhibits a focal ring with a locus of each of infinite focal points on the ring being displaced non-coaxially from the principal axis, and wherein the at least one treatment zone has an annular configuration sharing the principal axis with the center zone.

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

a center zone with a negative power for myopic vision correction, the center zone having a principal axis orthogonal to a surface thereof and passing through a center of the ophthalmic lens; and

at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile comprising a positive power relative to the center zone, the at least one treatment zone having a surface shape projecting outwardly from a front surface of said ophthalmic lens and comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone, and wherein the at least one treatment zone has a tilt angle between +0.035 and +0.3215 degrees relative to a zero-angle comparator, wherein the tilt angle is designated as zero when a central ray passing through a mid-annulus of the treatment zone passes through an intersection point of a retinal plane of a wearer of the ophthalmic lens and the principal axis, and wherein a positive tilt angle causes the central ray passing through the mid-annulus of the treatment zone to intersect the principal axis anterior to the retinal plane, and wherein the at least one treatment zone exhibits a focal ring with a locus of each of infinite focal points on the ring being displaced non-coaxially from the principal axis.
