Autorefraction versus subjective refraction in high astigmatism [PDF]

International Journal of Ophthalmology
AIM: To compare the subjective refraction data with auto-refraction findings in high astigmatisms. METHODS: In a cross-sectional study, sampling was done from in different geographic regions in Iran using a multistage random cluster sampling method.

Comparison of open-field autorefraction, closed-field autorefraction, and retinoscopy for refractive measurements of children and adolescents in Taiwan

Journal of the Formosan Medical Association, 2020
Purpose: To evaluate the accuracy and effectiveness of noncycloplegic and cycloplegic autorefraction using two types of autorefractors (ARs) compared with retinoscopy in children and adolescents. Methods: This cross-sectional study included 308 students (

Comparative Study of Refraction between Wave Front-Based Refraction and Autorefraction without and with Cycloplegia in Children and Adolescents

Children, 2022
The main aim of this study was to compare refraction measurements with and without cycloplegia from two refractors devices, (TRK-2P autorefractometer (TRK-2P) and wavefront-based refraction Visionix 130 (VX130)) in children and adolescents.

Autorefraction Versus Manifest Refraction in Patients With Keratoconus

Journal of Refractive Surgery, 2018
PURPOSE: To compare visual performance using autorefraction and manifest refraction assessments in patients with keratoconus and investigate whether autorefraction measurements lead to suboptimal visual performance. METHODS: Corrected distance visual acuity (CDVA) was measured in 90

Study on accommodation by autorefraction and dynamic refraction in children

Journal of Optometry, 2014
Purpose: Childhood accommodation interferes with accurate diagnosis of the latent refractive errors. Dynamic retinoscopy offers accurate measurements of accommodative response, while an autorefractometer can predict the accommodative system activation in
