Subjective 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 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 کاملCorrelation between Retinoscopy and Monocular and Binocular Subjective Refraction
Purpose: The aim of the study was to investigate if static retinoscopy has a higher correlation with monocular than binocular subjective refraction, and also to see if there is any difference between these results and Mohindra retinoscopy. Methods: Retinoscopy and subjective refraction was performed on 32 adult subjects and the results from 29 of these were analysed. Results: The statistical an...

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 کاملSubjective Image Quality Measurement
Estimating the subjective, human-perceived quality of an image can be very useful. For example, with an accurate measure of how interesting and attractive each photo from an event is we could create high quality, automated slideshows and summaries. Often people take multiple pictures of the same scene, and these quality metrics could also be used for deduplication: once duplicate images have be...
