Abstract Details


To characterize lens design and performance of the new TECNIS® Symfony Extended Range of Vision 1-Piece Intraocular Lens (IOL), Model ZXR00 (AMO).


Brest University Hospital - France


Simultaneous vision, or the presence of multiple focused images, in multifocal IOLs leads to halos and glare. Through-focus image quality and point spread function (PSF) simulations were evaluated in order to determine whether a second focus is provided by the new TECNIS® Symfony IOL. Comparisons are made to the 1-month results from a prospective, multicenter clinical study in the EU with bilateral implantations of the TECNIS® Symfony IOL, Model ZXR00, in 150 cataract patients. Key evaluation criteria were defocused visual acuity, subject reports of visual disturbances and patient satisfaction questionnaire responses.


Simulations of through-focus visual acuity and PSF of the TECNIS® Symfony IOL show a continuous range of vision and a lack of multiple distinct foci. Corresponding comparisons of defocused visual acuity, visual disturbances and resulting patient satisfaction data will be provided from the ongoing clinical study.


Simulations and optical bench measurements with the new TECNIS® Symfony IOL, Model ZXR00, show a continuous range of vision and PSFs that demonstrate reduced halos resulting in reduced optical/visual symptoms.
