PROGNOSIS OF REFRACTIVE CORRECTIONS
Ophthalmic and Physiological Optics, 1985Abstract— The validity and efficacy of the prognosis equation published by Saunders (1984b) is tested against previously reported longitudinal data. In a fair and random sample and over a short interval, nearly 60% of the sample was found to have a prediction error of less than 0.25 DS and, in 92%, the error involved was less than 0.5 DS.

Vision Evaluation of Eccentric Refractive Correction
Optometry and Vision Science, 2007This study investigates the benefits of eccentric refractive correction to resolution and detection thresholds in different contrasts for seven subjects with central visual field loss (CFL) and for four healthy control subjects with normal vision.Refractive correction in eccentric viewing angles, i.e., the preferred retinal location for the CFL ...

Fully 3D refraction correction dosimetry system
Physics in Medicine and Biology, 2016The irradiation of selective regions in a polymer gel dosimeter results in an increase in optical density and refractive index (RI) at those regions. An optical tomography-based dosimeter depends on rayline path through the dosimeter to estimate and reconstruct the dose distribution.

Refractive results with secondary piggyback implantation to correct pseudophakic refractive errors
Journal of Cataract and Refractive Surgery, 2005To assess the efficacy and safety of implanting a second intraocular lens (IOL) to correct pseudophakic refractive errors.Goldschleger Eye Institute, Sheba Medical Center, Tel Hashomer, Israel.This prospective noncomparative case series included 10 pseudophakic eyes, 5 with a myopic residual refractive error and 5 with a hyperopic residual refractive ...

Clinical Prediction of Postsurgical Aphakic Refractive Correction
Optometry and Vision Science, 1984A simple clinical predictor of the amount of spectacle convex lens power that will be needed to correct the refractive error of an aphakic patient after cataract surgery is developed based on clinical measures of anterior corneal surface power (keratometer measurements) and axial length. This predictor derived from matrix optics is compared to previous

Radiative corrections to neutrino indices of refraction
Physical Review D, 1987Quantum loop corrections to coherent forward neutrino scattering and , l=e,\ensuremath{\mu},\ensuremath{\tau} are examined in the standard SU(2${)}_{L}$\ifmmode\times\else\texttimes\fi{}U(1) model. For a neutral unpolarized medium with particle densities ${N}_{e}$=${N}_{p}$,${N}_{n}$ we find ${\mathit{p}}_{\mathit{v}}$(${\mathit{n}}_{\mathit{v}\mathit ...

Refractive corrections to scatter propagation
Journal of Geophysical Research, 1957The role played by the ionosphere's mean electron density for scatter propagation is considered. An electron plasma at the scattering point (1) increases the effective wavelength and (2) decreases the scattering angle. These effects combine to modify the basic propagation variable by a factor which depends only on the instantaneous maximum ...
