Proportion of onset of myopia and proportion of fast myopia progressor in each group.
Myopic progression is measured by change in spherical equivalent refraction (SER). Cycloplegic refraction is assessed by using an auto-refractometer. Eyeball growth is measured by change in axial length, using the IOL master.
