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.

Cycloplegia Improves the Inter-Optometrist Repeatability of Subjective Refraction

Photonics
Background: Since accommodation may be a source of error affecting the inter-optometrist repeatability of subjective refraction, this study investigated whether the use of cycloplegia could improve this repeatability.

The effect of cycloplegia in the accuracy of autorefraction, keratometry and axial length using the Myopia Master

BMC Ophthalmology
Background Assessing refractive errors under cycloplegia is recommended for paediatric patients; however, this may not always be feasible. In these situations, refraction has to rely on measurements made under active accommodation which may increase ...

Comparison of cycloplegia with atropine 1% versus cyclopentolate 1%

Indian Journal of Ophthalmology, 2023
Purpose: Cycloplegic refraction is mandatory for children to know the eye's refractive status. In this study, we compared cycloplegia induced by cyclopentolate 1% to that induced by atropine 1% by means of retinoscopy.
