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

1. A computer-implemented method for estimating and tracking refractive error progression of an individual, comprising:

estimating a percentile of Spherical Equivalent Refraction (SPHEQ) as a function of the individual'"'"'s age and at least one of country, region, gender, ethnicity, or parental history by comparison to a reference population by modeling data from a selected dataset;

estimating an expected SPHEQ trajectory of the individual over a future predetermined period of time using a predetermined set rate of change;

determining an expected SPHEQ trajectory using an ametropia control treatment;

displaying, on a graphic user interface, a comparison of the estimated expected SPHEQ trajectory of the individual with the expected SPHEQ trajectory using the ametropia control treatment;

displaying, on a graphic user interface, a comparison of the estimated percentile of SPHEQ with the estimated expected SPHEQ trajectory of the individual; and

using the comparisons to estimate and track the refractive error progression of the individual.
