Quality of vision with the Acri.Twin asymmetric diffractive bifocal intraocular lens system

Asymmetric bilateral implantation of the Acri.Twin IOL gave good simultaneous distance and near vision with improved contrast sensitivity under photopic and mesopic conditions. Differences between monocular and binocular visual acuity and contrast sensitivity were obtained because of the distance-/near-weighted light distribution of Acri.Twin IOLs.
