Third-order theory of spectacle lenses applied to correction of peripheral refractive errors.
PURPOSE To demonstrate that relatively simple third-order theory can provide a framework which shows how peripheral refraction can be manipulated by altering the forms of spectacle lenses. METHODS Third-order equations were used to yield lens forms that correct peripheral power errors, either for the lenses alone or in combination with typical peripheral refractions of myopic eyes. These resu...
متن کاملPeripheral refraction profiles in subjects with low foveal refractive errors.
PURPOSE To study the variability of peripheral refraction in a population of 43 subjects with low foveal refractive errors. METHODS A scan of the refractive error in the vertical pupil meridian of the right eye of 43 subjects (age range, 18 to 80 years, foveal spherical equivalent, < ± 2.5 diopter) over the central ± 45° of the visual field was performed using a recently developed angular sca...
متن کاملCorrecting quantum errors with entanglement.
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error-correcting codes, thus allowing us to "quantize" all of classical linear coding theory. In particular, efficient modern classical codes that attain t...
متن کاملPeripheral refractive errors in myopic, emmetropic, and hyperopic young subjects.
To gain more insight into the relationship between foveal and peripheral refractive errors in humans, spheres, cylinders, and their axes were binocularly measured across the visual field in myopic, emmetropic, and hyperopic groups of young subjects. Both automated infrared photorefraction (the "PowerRefractor"; www. plusoptix.de) and a double-pass technique were used because the PowerRefractor ...
متن کاملRefractive accuracy with light-adjustable intraocular lenses.
PURPOSE To evaluate efficacy, predictability, and stability of refractive treatments using light-adjustable intraocular lenses (IOLs). SETTING University Hospital Virgen de la Arrixaca, Murcia, Spain. DESIGN Prospective nonrandomized clinical trial. METHODS Eyes with a light-adjustable IOL (LAL) were treated with spatial intensity profiles to correct refractive errors. The effective chang...
