Study of Theories about Myopia Progression (STAMP) design and baseline data.

ABSTRACT:

Purpose

The Study of Theories about Myopia Progression (STAMP) is a 2-year, double-masked, randomized clinical trial of myopic children 6 to 11 years of age. STAMP will evaluate the 1-year effect of progressive addition lenses (PALs) compared with single vision lenses (SVLs) on central refraction, peripheral refraction in four quadrants, and accommodative response and convergence. STAMP will also evaluate any changes 1 year after discontinuing PALs. Baseline characteristics of enrolled children are reported.

Methods

Eligible children had a high accommodative lag and either low myopia (less myopic than -2.25 diopter (D) spherical equivalent) or high myopia (more myopic than -2.25 D spherical equivalent) and esophoria at near. Children were randomly assigned to wear either PAL
