A system, method and computer program product for estimating future axial elongation of an individuals 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 reference timepoint 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, a future 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 prior pre-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.
