Ametropia treatment tracking methods and system. A system, method and computer program product for estimating future axial elongation of an individual's eye as a way to predict and track refractive error progression of an individual. The method includes: receiving, via a computer interface, data relating to refractive change in a prior pre-determined time period for the individual from a referencetimepoint; receiving data representing an age of the individual and data representing a current axial length value of the eye as measured at the reference timepoint; calculating, by said processor, afuture axial elongation of the eye as a function of the age of the individual, the current axial length value of the eye as measured at the reference timepoint, and the refractive change in the priorpre-determined time period; generating, an output indication of said computed axial elongation of the eye, and using said output indication to select a myopia control treatment for said individual.
