Abstract

A method for estimating and tracking refractive error progression of an individual includes estimating a percentile of Spherical Equivalent Refraction (SPHEQ) as a function of at least the individual'"'"'s age by comparison to a reference population; estimating an expected SPHEQ trajectory over a future predetermined period of time; comparing the expected SPHEQ trajectory with the reference population; and comparing the expected SPHEQ trajectory with an expected SPHEQ trajectory using an ametropia control treatment, thereby showing a possible treatment benefit over the predetermined period of time.

Claims

estimating a percentile of Spherical Equivalent Refraction (SPHEQ) as a function of at least the individual'"'"'s age by comparison to a reference population;

estimating an expected SPHEQ trajectory over a future predetermined period of time;

comparing the expected SPHEQ trajectory with the reference population; and

comparing the expected SPHEQ trajectory with an expected SPHEQ trajectory using an ametropia control treatment, thereby showing a possible treatment benefit over the predetermined period of time.

2. A method according to claim 1, further comprising estimating probabilities of errors of the expected SPHEQ trajectory over the predetermined period of time.

3. A method according to claim 1, further comprising:

measuring actual SPHEQ refraction history for the individual and comparing to a reference population; and

estimating an updated expected SPHEQ trajectory.

4. A method according to claim 1, further comprising:

measuring actual SPHEQ refraction history for the individual while using a given ametropia control treatment and comparing to a reference population; and

estimating an updated expected SPHEQ trajectory, thereby showing actual treatment benefit over a predetermined period of time.

5. A method according to claim 1, wherein said estimating a percentile of SPHEQ comprises modeling population reference percentiles of SPHEQ from a selected dataset comprising Spherical Equivalent Refraction data as a function of age and at least one of country, region, gender, ethnicity, or parental history.

6. A method according to claim 5, wherein the population reference percentiles comprise curves in selected percentile increments.

7. A method according to claim 1, wherein said estimating an expected SPHEQ trajectory over a future predetermined period of time is a function of a baseline age of the individual and a baseline SPHEQ.

8. A method according to claim 1, wherein said estimating an expected SPHEQ trajectory over a future predetermined period of time is a function of a baseline age of the individual, a baseline SPHEQ, and past refractive history.

9. A method according to claim 8, wherein the past refractive history comprises a progression rate of between 0.5 D to 1.5 D per year.

10. A method according to claim 1, wherein the ametropia control treatment comprises a myopia control ophthalmic lens.

14. A method according to claim 4, further comprising:

measuring actual SPHEQ refraction history for the individual while using a given ametropia control treatment at periodic intervals;

estimating an updated expected SPHEQ trajectory at each interval; and

saving data comprising the updated expected SPHEQ trajectory at each interval to a secure server or database.

15. A method according to claim 14, further comprising providing access to a user authorized to view said saved data.

16. A method according to claim 14, wherein said authorized user comprises at least one of an Eye Care Provider, customer, parent, or child.

17. A method according to claim 14, further comprising:

providing said saved data to a third party, said data comprising age and SPHEQ refraction measurements; and

updating a database comprising clinical data on efficacy of the ametropia control treatment.

18. A method according to claim 14, comprising saving data for a plurality of children and/or for a plurality of ametropia treatment options.
