A new soft lens called SV-38, with an aspherical front curve, should enhance the quality of vision since it controls better for spherical aberration. We compared the visual performance of spectacles, SV-38 and one type of conventional spherical soft lens on 28 eyes. The results of the ...

The designs of aspheric IOLs are based on the average corneal spherical aberrations reported in large-scale clinical studies to achieve ideal outcomes for subjects with ocular aspherical aberrations. However, few studies have investigated the distribution of corneal spherical aberrations in cataract patients...
