This study investigated differences in geometrical properties and optical aberrations
between a group of hyperopes and myopes (age-matched 30.3±5.2 and 30.5±3.8 years old …

Purpose. Myopia has been found to be predominantly axial in nature, ie myopic eyes have
longer than normal axial lengths, with corneal radius variations having only a small …

We measured optical and biometric parameters of emmetropic eyes as a function of age.
There were approximately 20 subjects each in age groups 18–29, 30–39, 40–49, 50–59 …

Background: The relationship between monochromatic aberrations of the human eye and
myopia has been investigated extensively over the past decade or so but the results are …

Total ocular higher order aberrations and corneal topography of myopic, emmetropic and
hyperopic eyes of 675 adolescents (16.9±0.7 years) were measured after cycloplegia using …

Purpose To evaluate the correlation between refractive error and higher-order aberrations
(HOAs) in patients with myopic astigmatism. Methods HOAs were measured using the …

Interest in peripheral refractive errors has increased as it was hypothesized that peripheral
hypermetropia might provide a stimulus for axial elongation (Smith et al., 2005), this study …

The progression of myopia is thought to be controlled by the retinal image quality, but its
triggering factors are not yet well known. The differences between the peripheral optics in …

Abstract purposes. To determine axial, vertical, and horizontal eye dimensions in myopic
and emmetropic eyes by using magnetic resonance imaging (MRI) and to relate these to …

Introduction: This study aims to understand off-axis refraction during accommodation and to
identify whether the relative hyperopia generally observed in myopic eyes changes with …
