Accuracy of WASCA aberrometer refraction compared to manifest refraction in Chinese adult myopes.
PURPOSE To investigate the accuracy of the Carl Zeiss Meditec Wavefront Supported Custom Ablation (WASCA) aberrometer in refraction testing for Chinese myopic adults. METHODS Manifest refraction and WASCA were performed on 360 eyes of 360 consecutive Chinese myopic adults without cycloplegia. Both vector analysis and conventional notation were applied for comparing results, and differences be...
متن کاملComparison of self-refraction using a simple device, USee, with manifest refraction in adults
BACKGROUND The USee device is a new self-refraction tool that allows users to determine their own refractive error. We evaluated the ease of use of USee in adults, and compared the refractive error correction achieved with USee to clinical manifest refraction. METHODS Sixty adults with uncorrected visual acuity <20/30 and spherical equivalent between -6.00 and +6.00 diopters completed manifes...
متن کاملThe precision of wavefront refraction compared to subjective refraction and autorefraction.
PURPOSE To determine the precision (repeatability) of several methods of calculating refraction from higher-order wavefront aberration data and to compare these wavefront refractions with lower-order (LO) wavefront refraction, subjective refraction, and autorefraction. METHODS Four clinicians refracted 16 normal participants aged 23.6 +/- 1.2 years, 69% female with an average spherical equiva...
متن کاملCycloplegic Refraction in Children with Cyclopentolate versus Atropine
The refracting power of the eye results from the static power of the eye (the combined ability of the cornea and the lens to bend incoming rays of light) and the accommodative power of the eye (the variable force of accommodation that alters the path of light rays by causing the ciliary body to change the curvature of the lens). The total increase in plus power that accommodation produces is kn...
متن کاملAccuracy of PlusOptix A09 distance refraction in pediatric myopia and hyperopia
BACKGROUND The PlusOptix photoscreeners (PlusOptix GmbH, Nuremberg, Germany) is used in many vision screening programs. The purpose of the present study was to further explore the accuracy of the PlusOptix A09 photoscreener in children with ametropia (myopia or hyperopia). METHODS A total of 70 eyes (35 children) were prospectively included. Before administration with the cycloplegia treatmen...
