Intermediate optimization of vision with bilateral nonaspheric multifocal intraocular lens implantation

Abstract

Intermediate optimization with slight myopia in 1 eye after bilateral implantation of the multifocal IOL offered consistent good vision at all ranges, indicating it a safe option for patients who require good vision at intermediate ranges.

Long-term Visual Function and Patient Satisfaction After Bilateral Implantation and Combination of Two Similar Multifocal IOLs

“…Vice versa, diffractive multifocal IOLs have been combined with mini-monovision strategies to increase visual function at intermediate distances. 17,20 Recently, trifocal diffractive IOLs have been proposed to increase intermediate visual acuity. 21 The introduction of diffractive multifocal IOLs with lower near additions yielded better results at intermediate distance without decreasing near and distance visual acuity.…”

Visual outcomes after bilateral trifocal diffractive intraocular lens implantation

“…Blaylock et al [ 10 ] reported that after the implantation of a Restor +4D in 37 eyes (Alcon, USA), monocular distance visual acuity improved from logMAR 0.09 ± 0.10 without correction to logMAR 0.00 ± 0.05 with best correction. De Vries et al [ 11 ] described uncorrected and best-corrected monocular visual acuity values of 0.04 ± 0.14 and −0.04 ± 0.09 after Restor +3D implantation (68 eyes) and of 0.14 ± 0.10 and −0.01 ± 0.06 after Restor +4D implantation (46 eyes), respectively.…”

“…The defocus curves of the studies by de Vries et al [ 11 ] (monocular) for Acrysof Restor +4D and +3D, by Toto et al [ 20 ] for Tecnis +4D, by Blaylock et al [ 10 ] for Acrysof Restor +4D, and Alfonso et al [ 2 ] (binocular) for Acrysof Restor + 4D, +3D, Acrilisa, all revealed a decrease in visual acuity (from logMAR 0.2 to 0.4) between −1 D and −1.5 D that we did not observe in our defocus curve. The decrease in visual acuity in the intermediate range of the defocus curve (from −1.00 to −2.00D) was no longer observed with the FineVision IOL.…”

Evaluation of Visual Outcomes in Patients Implanted with Acri.LISA 356D Multifocal Intraocular Lens

“…Burada hastalar›n gözlük kullanma konusundaki isteksizliklerinin nedeni muhtemelen gözlüksüz ara mesafe görme seviyelerini miyopik kayman›n art›rm›fl olmas›ndan kaynaklanmaktad›r. Blayblock ve arkadafllar›n›n 15 yapt›¤› çal›flmada, ReStor implante edilen hastalara, hesaplanan G‹L de¤erinden 1 D fazla güçte lens implante edilmifl ve hastalar›n ara mesafedeki görmelerinin, yak›n ve uzak gör-meleri kadar iyi oldu¤u ölçülmüfltür.…”
