Peripheral refraction with different designs of progressive soft contact lenses in myopes
Aim: The purpose of this study was to compare the changes in relative peripheral refractive error produced by two different designs of progressive soft contact lenses in myopic schoolchildren. Methods: Twenty-seven myopic schoolchildren age between 13 to 15 years were included in this study. The measurements of central and peripheral refraction were made using a Grand-Seiko WR-5100K open-field ...
متن کاملChanges in Peripheral Refraction, Higher-Order Aberrations, and Accommodative Lag With a Radial Refractive Gradient Contact Lens in Young Myopes.
PURPOSE To evaluate changes in the peripheral refraction (PR), visual quality, and accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact lens that produces peripheral myopic defocus. METHODS 59 myopic right eyes were fitted with the lens. The PR was measured up to 30° in the nasal and temporal horizontal visual fields and compared with values obtained with...
متن کاملEvaluating the peripheral optical effect of multifocal contact lenses.
PURPOSE Multifocal soft contact lenses have been used to decrease the progression of myopia, presumably by inducing relative peripheral myopia at the same time as the central image is focused on the fovea. The aim of this study was to investigate how the peripheral optical effect of commercially available multifocal soft contact lenses can be evaluated from objective wavefront measurements. M...

26 Objective: To evaluate changes in the peripheral refraction (PR), visual quality, and 27 accommodative lag (LAG) with a novel soft radial refractive gradient (SRRG) 28 experimental contact lens that produces peripheral myopic defocus. 29 Methods: Fifty-nine myopic right eyes were fitted with the lens. The PR was measured 30 up to 30 degrees in the nasal and temporal horizontal visual fields ...
متن کاملPeripheral Design of Progressive Addition Lenses and the Lag of Accommodation in Myopes.
Purpose Insufficient accommodative response is assumed to result in myopia progression. We have investigated if the accommodative lag in myopes is different between a single vision lens (SVL) and the progressive addition lens PAL 2, clinically trialled for its ability to reduce progression of myopia, and if there exist differences in accommodative lag between PAL 2 and other PALs with the same ...
