Study on accommodation by autorefraction and dynamic refraction in children.
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 children. A correlation of the accommodative effort with the dynamic refraction has been investigated in emmetropic children, before and after ...
متن کاملThe Refraction and Accommodation of the Eye
The apparent simplicity of the adaption of lenses to imperfect vision is seen in the fact that the public consider watchmakers competent to help them in a selection of spectacles, or else they seek the aid of an ophthalmic optician, who, ignorant alike of physical optics and the physiology of the eye, advertises his ability to " suit all sights." Undoubtedly the most important agent in the whol...
متن کاملSubjective refraction in eyes with multifocal IOLs.
To the Editor: Piñero et al,1 in the August 2010 issue of the Journal of Refractive Surgery, addressed the complexity of obtaining refraction in eyes that have been implanted with multifocal intraocular lenses (IOLs). It has been shown that automated and wavefront refractors may not yield accurate measurement of residual refractive error for secondary laser vision correction in eyes with multif...
متن کاملcomparison of subjective refraction, predicted phoropter refraction (ppr) by zywave aberrometer, and final surgical plan used for laser vision correction
purpose: to study the validity and reliability of subjective refraction, predicted phoropter refraction (ppr) measured by zywave aberrometer, and final surgical plan applied for laser vision correction. methods: this prospective study was conducted on 94 myopic or myopic astigmatic eyes (48 patients) who were candidates for refractive surgery in negah eye hospital from april 2012 to july 2012. ...
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...
