Influence of the pupil size on visual quality and spherical aberration after implantation of the Tecnis 1-piece intraocular lens

The aspheric profile of the Tecnis 1-piece IOL reduces total spherical aberration to virtually zero at all pupil sizes from 3-6 mm. Thus, visual acuity, contrast sensitivity, refraction and defocus curve show the same good results at large pupil sizes compared with small pupil sizes.
