Changes in the anterior segment after cycloplegia with a biometer using swept-source optical coherence tomography.

PLoS ONE, 2017
The aim of this study was to investigate changes in the anterior segment of the eye after cycloplegia. A biometer combined with swept-source optical coherence tomography (SSOCT) was used for measurements.

Light distortion and spherical aberration for the accommodating and nonaccommodating eye [PDF]

, 2016
To evaluate how different amounts of induced spherical aberration (SA) affect the light distortion (LD) phenomena, tests were performed using an experimental device to measure the distortion (haloes, glare, and so on) of a point source. To simulate the

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

Use of atropine to predict the accommodative component in esotropia with hypermetropia

Indian Journal of Ophthalmology, 2011
This cohort study included children with esotropia and hypermetropia of ≥ +2.0 diopters (D). The deviation was measured at presentation, under atropine cycloplegia and 3 months after full refractive correction. Of 44 children with a mean age of 5.2 ± 2.4
