Evaluation of the Aspheric Tecnis Multifocal Intraocular Lens: One-Year Results from the First Cohort of the Food and Drug Administration Clinical Trial

Desempenho visual dos pacientes pseudofácicos com diferentes lentes intraoculares

“…In this study, high-contrast uncorrected near and far visual acuity tested using the ETDRS™ chart in most everyday situations was similar for both IOLs, but the Tecnis™ MF group was statistically superior for uncorrected intermediate visual acuity, in agreement with the criteria of normality previously established and described by several authors (10,15,22,23) . We found a better monocular intermediate visual acuity corrected for far vision in the multifocal group (ReSTOR™, Tecnis™ MF) compared with the monofocal group (SN60AT; SN60AT) for distances of 40-50 cm.…”

“…At 50-60 cm corrected for far vision the Tecnis™ MF group was statistically superior to all other groups. One possible explanation for this result is that the (22,23) . Hützet et al (23) reported similar data on the superiority of Tecnis™ MF lenses for intermediate vision compared with ReSTOR™ and other monofocal lenses.…”

“…Several studies on the measurement of contrast sensitivity, aberrometry, and reading speed associated with objective measurement of visual acuity and satisfaction questionnaires provide an extensive evaluation of the optical quality and visual performance of implanted IOLs (11,22,25) . The contrast sensitivity results in our study are in agreement with the literature for different spatial frequencies: among patients using ReSTOR™ lenses, there was a decrease in contrast sensitivity at certain frequencies (12 and 18 cpd), while it remained normal at other frequencies (3 and 6 cpd) (24) .…”

Inadvertent implantation of a reversed-optic Tecnis ZM900 multifocal intraocular lens: case report

“…Along with the corneal optics, the geometry and positioning of the IOL contribute to the eye's optical quality (4,5) . The literature offers little information related to the inadvertent implantation of a reversed-optic posterior chamber IOL and no information related to a reversed-optic multifocal IOL.…”

Newer Intraocular Lenses in Present Day Cataract Surgery

“…These IOLs provide high levels of spectacle independence 11 and their mechanism of action is independent of ciliary body function. They are currently the most reliable lens for attaining both distance and near vision.…”
