Functional outcomes after implantation of Tecnis ZM900 and Array SA40 multifocal intraocular lenses

Abstract

The aspherical diffractive Tecnis multifocal IOL gave better outcomes than the Array multifocal IOL.

Clinical Outcomes Following Implantation of Diffractive Multifocal Intraocular Lenses With Varying Add Powers

“…18 Another study also demonstrated that eyes with the ZM900 had better mesopic contrast sensitivity than eyes with refractive multifocal IOLs. 19 Eyes with the ZMB00, a 1-piece acrylic multifocal IOL, had even better contrast sensitivity than eyes with the ZM900 over a shorter time period than eyes with the ZM900. 12 In our study, we found that contrast sensitivity and spherical aberration values of the new TECNIS multifocal IOLs were similar to those of the ZMB00 and to those measured in previous studies.…”

Predictive factor and kappa angle analysis for visual satisfactions in patients with multifocal IOL implantation

“…Researchers have noted these factors, and some studies have analyzed the governing factors for patient satisfaction after implantation of multifocal IOLs. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Causes associated with photic phenomena noted in previous studies have included IOL decentration, retained lens fragment, posterior capsular opacification, dry-eye syndrome, uncorrected visual acuity (UCVA), use of spectacles for distance purposes, postoperative astigmatism, and postoperative spherical equivalent. 9,21 However, none of the studies in published literature have evaluated the role of misalignment between the visual axis and the pupillary axis, or the angle kappa, as a specific predictor for patient symptoms.…”

Estudo comparativo do desempenho visual e análise de frente de onda entre as lentes intra-oculares multifocais difrativas Tecnis® ZM900 e AcrySof® ResTor® SN60D3

“…Muitas formas de abordagem com o objetivo de correção da presbiopia foram tentadas, como monovisão e miopização contralateral (1)(2) . As lentes intra-oculares (LIOs) multifocais tentam compensar a eventual perda de estereopsia e visão binocular que limitavam as estratégias usadas com as LIOs monofocais.…”

“…As lentes intra-oculares (LIOs) multifocais tentam compensar a eventual perda de estereopsia e visão binocular que limitavam as estratégias usadas com as LIOs monofocais. Apesar de se mostrarem efetivas na visão de perto e de longe, uma limitação destas lentes, sejam refrativas ou difrativas, é a dispersão de energia, que leva à formação de halos e "glare" e à redução da sensibilidade ao contraste (1)(2)(3)(4)(5)(6)(7) . As modificações no cristalino que ocorrem com o passar do tempo levam à diminuição da sensibilidade ao contraste (8) .…”
