Optical quality is usually characterized for fixed pupil diameters. Results obtained in a study that assesses the visual acuity and ocular aberrations with multifocal spherical correction and the interaction with pupil size; show that wavefront analysis should be treated carefully. Intrapolating or extrapolating the aberrations for an alternative pupil size could lead to significant differences in understanding the impact of aberrations from what is seen from natural pupil size particulary with multifocal correction.

This study was presented in a poster at OPTOM16, the 24th international congress of optometry, contact lenses and ophthalmic optics held in Madrid.
