The 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 کاملComparison of refractive assessment by wavefront aberrometry, autorefraction, and subjective refraction.
PURPOSE To compare refractive assessment results obtained with an aberrometer, an autorefractor, and manual subjective refraction (SR) in a healthy population with optimal visual potential. METHODS Sixty adults aged 18-59 years with visual acuity of 20/25 or better, no media opacity, and no known corneal or retinal abnormalities were recruited during the course of routine eye examination. Ref...
متن کاملWavefront refraction and correction.
Galileo Galilei, the father of experimental science, taught that to understand nature, you must measure nature. Galileo’s contemporary, Christophoro Scheiner, explored the nature of eyes as optical instruments and discovered how to measure the eye’s focusing distance simply by viewing a point of light through closely spaced pinholes in an opaque card. Two centuries later, Thomas Young used Sche...
متن کاملA comparison of autorefraction and subjective refraction with and without cycloplegia in primary school children.
PURPOSE To evaluate the accuracy of autorefraction using three autorefractors comparing to subjective refraction in diagnosing refractive error in children. DESIGN A cross-sectional study. METHODS setting: Community based study. study population: 117 children sampled from primary schools. procedures: All subjects underwent autorefraction using three auto refractors and subjective refraction...
متن کاملClinical Applications of Wavefront Refraction
PURPOSE To determine normative reference ranges for higher-order wavefront error (HO-WFE), compare these values with those in common ocular pathologies, and evaluate treatments. METHODS A review of 17 major studies on HO-WFE was made, involving data for a total of 31,605 subjects. The upper limit of the 95% confidence interval (CI) for HO-WFE was calculated from the most comprehensive of thes...
