Purpose: To determine the natural end-point for refractive development during childhood. Methods: Cycloplegic (1% cyclopentolate) autorefraction was performed on 38 811 children aged 5 and 15 in population-based samples at eight sites in the Refractive Error Study in Children (RESC). Refractions (right eye) were categorized as myopic (≤-0.5 D), emmetropic (>-0.5 to ≤+0.5 D), mildly hyperopic (>+0.5 to ≤+2.0 D and hyperopic (>+2.0 D). Results: At five sites (Jhapa - rural Nepal, New Delhi -...[Show more]
