Increased hyperopia with ageing based on cycloplegic refractions in adults: the Tehran Eye Study

Abstract

Although an age-cohort effect cannot be ruled out, these results provide the first population-based evidence of increasing hyperopia with age using cycloplegic refraction. The results obtained suggest that the contribution of decreasing accommodation to observed hyperopic shifts in distance refraction in longitudinal studies is small, raising the question of the underlying causes of the hyperopic shift in refraction with age.
