Abstract

Certain embodiments of the present invention are directed to therapeutic intervention in patients with eye-length-related disorders to prevent, ameliorate, or reverse the effects of the eye-length-related disorders. Embodiments of the present invention include methods for early recognition of patients with eye-length-related disorders, therapeutic methods for inhibiting further degradation of vision in patients with eye-length-related disorders, reversing, when possible, eye-length-related disorders, and preventing eye-length-related disorders. Additional embodiments of the present invention are directed to particular devices used in therapeutic intervention in patients with eye-length-related disorders.

First claim

The invention claimed is:

1. A therapeutic treatment method for preventing, ameliorating, or reversing eye-length-related disorders, the therapeutic treatment method comprising:
identifying, in a patient, a disorder of a patient's eye, said disorder being an eye-length-related disorder; and
inhibiting further lengthening of the patient's eye by providing the patient with a therapeutic device comprising a first ophthalmic lens, the first ophthalmic lens comprising:
a first area of the first ophthalmic lens including a plurality of first elements selected from the group consisting of:
(i) bumps on a surface of the first lens;
(ii) depressions on the surface of the first lens;
(iii) first translucent inclusions in a first lens material; and
(iv) first transparent inclusions in the first lens material, the first transparent inclusions having a refractive index different from that of the first lens material,

wherein the elements are dot-shaped elements having a non-zero dot density in a range between 0 and 8 dots per mm 2 .

2. The therapeutic treatment method of claim 1 , wherein said inhibiting includes having the patient to wear a therapeutic device in which the first ophthalmic lens further comprises a second area that is surrounded by the first area of the first ophthalmic lens, said second area being free of the elements.

3. The therapeutic treatment method of claim 2 , wherein said inhibiting includes having the patient to use the first ophthalmic lens in which a density, dimension, and material of the first elements are selected to reduce a visual acuity in a patient's vision when looking through the first area.

4. The therapeutic treatment method of claim 3 , wherein said inhibiting includes having the patient to use the first ophthalmic lens in which the density, dimension, and material of the first elements in the first area are selected to reduce a visual acuity from 20/20 when a line of sight of the patient looking through the first lens passes through the second area to about 20/25 when the line of sight the patient passes through the first area.

5. The therapeutic treatment method of claim 1 , wherein said inhibiting includes having the patient to wear the therapeutic device in which the first elements are sized and shaped to scatter light incident thereon to cause blurring of an image in a peripheral vision of the patient.

6. The therapeutic treatment method of claim 1 , wherein said identifying the eye-length-related disorder comprises one or more of:
conducting a direct measurement of an axial length of the patient's eye;
conducting a vision-acuity test; and
sequencing opsin genes of the patient to determine types of opsin variants that occur within the patient.

7. The therapeutic treatment method of claim 1 , wherein the inhibiting includes causing the patient to wear the therapeutic device that is a pair of eyeglasses comprising the first ophthalmic lens.

8. The therapeutic method of claim 7 , wherein the inhibiting includes causing the patient to wear a pair of eyeglasses that comprises a second ophthalmic lens, the second ophthalmic lens comprising:
a third area including a plurality of second elements selected from the group consisting of:
(i) bumps on a surface of the second lens;
(ii) depressions on the surface of the second lens;
(iii) second translucent inclusions in a second lens material; and
(iv) second transparent inclusions in the second lens material, the first transparent inclusions having a refractive index different from that of the second lens material;

wherein the elements are dot-shaped elements having a non-zero dot density in a range between 0 and 8 dots per mm 2 .

9. The therapeutic method of claim 8 , wherein said inhibiting includes using a spatial pattern of the first elements of the first ophthalmic lens is different from a spatial pattern of the second elements of the second ophthalmic lens.

10. An ophthalmic lens, comprising:
a first area comprising a plurality of elements selected from the group consisting of:
(i) bumps on a surface of the lens;
(ii) depressions on the surface of the lens;
(iii) translucent inclusions in a lens material; and
(iv) transparent inclusions in the lens material, the transparent inclusions having a refractive index different from that of the lens material; and

a second area surrounded by the first area, the second area being free of the elements,
wherein the elements are dot-shaped elements having a non-zero dot density in a range between 0 and 8 dots per mm 2 .

11. The ophthalmic lens of claim 10 , wherein a density, dimension, and material of the elements are selected to reduce a visual acuity in the patient's peripheral vision.

12. The ophthalmic lens of claim 11 , wherein the density, dimension, and material of the elements in the first area are selected to reduce a visual acuity from 20/20 when a line of sight of a user looking through the lens passes through the second area to about 20/25 when the line of sight of the user passes through the first area.

13. The ophthalmic lens of claim 10 , configured as a lens in a pair of glasses and wherein the elements are sized and shaped to scatter light incident thereon to cause blurring of an image in a peripheral vision of the user wearing said pair.

14. A pair of eyeglasses, comprising:
a first ophthalmic lens and a second ophthalmic lens, each of the first and second ophthalmic lenses comprising a pattern of elements selected from the group consisting of:
(i) bumps on a surface of a corresponding lens from said first and second lenses;
(ii) depressions on the surface of the corresponding lens;
(iii) translucent inclusions in a corresponding lens material; and
(iv) transparent inclusions in the corresponding lens material, the transparent inclusions having a refractive index different from that of the corresponding lens material; and

wherein, for each of patterns of elements of the first and second ophthalmic lenses, a density of the elements in a peripheral region of the corresponding lens is higher than a density of the elements in a central region of the corresponding lens,
and wherein the elements are dot-shaped elements having a non-zero dot density in a range between 0 and 8 dots per mm 2 in at least a first area of each lens.

15. The pair of eyeglasses of claim 14 , wherein the density, a dimension, and a material of the elements are selected to reduce a visual acuity in a peripheral visual field of a user wearing said pair.

16. The pair of eyeglasses of claim 15 , wherein the density, dimension, and material of the elements in the first area of each lens are selected to reduce a visual acuity of the user wearing said pair from 20/20 when a line of the user's sight passes through a second area of the corresponding lens to about 20/25 when the line of user's sight passes through the first area, the first and second areas being different from one another.

17. The pair of eyeglasses of claim 16 , wherein the elements are sized and shaped to scatter light incident thereon to cause blurring of an image in a peripheral visual field of the user wearing said pair.

18. The pair of eyeglasses of claim 14 , wherein a pattern of elements of the first ophthalmic lens is different from a pattern of elements of the second ophthalmic lens.

19. The pair of eyeglasses of claim 14 , wherein the first ophthalmic lenses comprises a central area surrounded by the pattern of the elements, the central area being free of the elements.
