Changes in refractive errors related to spectacle correction of hyperopia. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Hyperopic undercorrection is a common clinical practice. However, less is known of its effect on the change in refractive errors and emmetropization throughout the later years of childhood.

Corneal shape in hyperopia [PDF]

open access: yesClinical and Experimental Optometry, 1998
Background: A trend towards decreased peripheral corneal flattening with increasing myopia has recently been demonstrated. The present study was conducted to determine whether corneal asphericity also varies significantly with hyperopic refractive error.

The influence of age, sex and visual dysfunction on reading ability in school-children [PDF]

open access: yesEPJ Web of Conferences, 2020
Binocular and accommodative dysfunctions affect the efficiency and coordination of the eyes, and this may impair reading performance. Reading can be evaluated using accuracy and speed measures. In this study, we searched for evidence that dysfunctions of
