Abstract Details


To compare the defocus curves yielded by 9 different models of multifocal IOLs: 3 bifocal lenses, an extended-range-of-focus lens and 5 trifocal lenses


IOA Madrid Innova Ocular, Spain


This study included 135 eyes from 135 patients split into 9 groups according to the implanted lens type. The lenses under assessment were the bifocal lens models Tecnis One ZMB, ZLB y ZKB (Abbott Laboratories); the extended range of vision lens Symfony (Abbott Laboratories), and the trifocal lenses AT LISA tri 839MP (Carl Zeiss Meditec), FineVision Micro F and POD Finevision (Physiol), Panoptix (Alcon Laboratories) and Tri-Ed 611 Acriva Reviol (VSY Biotechnology). The defocus curves were obtained monocularly by measuring VA with the best far-distance correction in the -5.00-to-+3.00 D range, in steps of 0.5 D. ETDRS test was employed


Regarding far-distance vision, no statistically significant differences were found across the lens models under study. On the contrary, for intermediate and near distances relevant differences did emerge. The worst quality of vision for intermediate distances was given by the Tecnis One ZMB model, whereas for near vision (30 cm) it was the Symfony model that yielded the lowest VA values. The ZLB model, despite its bifocal design, showed a very similar behaviour to that of a trifocal lens. The FineVision lens models, both the Micro and the POD versions, achieved a more homogenous quality of vision across all distances


Each multifocal IOL’s defocus curve depends mainly on its addition for near vision and on the number of foci that the lens has. The resulting defocus curve can help ophthalmologists to select the most appropriate lens according to the specific patient needs
