Correlation of pupil size with visual acuity and contrast sensitivity after implantation of an apodized diffractive intraocular lens

Abstract

Conclusions A larger pupil was correlated significantly with better distance visual acuity and with worse near visual acuity. For all pupil diameters, intermediate visual acuity worsened significantly as the distance of the test increased. Distance contrast sensitivity was better with larger pupils at all spatial frequencies in bright-light and dim-light conditions.
