Gracia P, et al. - The purpose of this research was to gauge the significance of orientation of multifocal lens designs with angular increments of addition. It was deduced that the optical aberration distributions for the group of physiologically normal eyes exhibited improved performance for some lens design orientations (i.e., left-right segments for 2-zone bifocals). Considering the higher-order aberrations (HOAs) of healthy patients, with a special focus on coma and spherical aberration, would raise the optical quality of angularly divided multifocal solutions.
