Evidence-based contact lens practice involves finding, appraising and applying research
findings as the basis for patient management decisions. These decisions should be …

Purpose: The purpose of this study was to determine the accuracy and repeatability of
refractive errors obtained using three autorefractors based on different measurement …

Objective. To investigate refractive development and prevalence of myopia in children aged
3‐6 years in Hebei Province, China, and to explore the developmental law of refraction, so …

It is important to predict which astigmatic patients require separate refraction for near vision.
This study compared cylindrical components changes by cyclopentolate 1% for the low and …

Dioptric power measurement is classically achieved using manual focimeters. In this
contribution, we present vectofocimetry as a novel methodology to be easily implemented in …

Purpose: Refractive errors are the first cause of visual impairment across the world.
Prevalence data are crucial for planning visual health strategies, since early detection and …

Aim To understand the views of contact lens (CL) practitioners across the globe regarding
what they perceive as opportunities and threats in CL practice. Methods A self-administered …

Previous studies have demonstrated that orientation-specific deprivation in early life can
lead to neural deficits of spatial vision in certain space, and can even result in meridional …

High lateral resolution (∼ 5µm) optical coherence tomography (OCT) that employs a
variable cross-cylinder (VCC) to compensate for astigmatism is presented for visualizing …

Backgrounds Aniso-astigmatism may hinder normal visual development in preschool
children. Knowing its prevalence, biometric parameters and risk factors is fundamental to …
