“…13 Montés-Micó and coauthors 13 reported that patients with multifocal IOLs had worse CSF under dim conditions. Studies evaluating the CSF after hybrid multifocal IOL implants 20,26,29,30,32,35,38,39,43,[46][47][48][49][50] also found a reduction in contrast sensitivity when the luminance level was reduced, particularly for higher spatial frequencies. This trend agrees with classic data on the effect of the luminance level on contrast sensitivity.…”

“…Many studies [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] have evaluated distance and near visual acuity after hybrid multifocal IOL implantation (Tables 1 and 2). In most of these studies, average monocular distance visual acuity (VA) and corrected for distance near vision (NV) after multifocal IOL implantation were better than 0.1 logMAR (about 6/7.5), with most eyes maintaining or improving both VA and distance corrected near vision.…”

It has been suggested that CSF under photopic and mesopic conditions, after multifocal IOL implantation, must be lower than that obtained after monofocal IOL implantation, but still within the normal range.…”

During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a satisfactory full range of visual functions, including patients of particular characteristics such as highly ametropic or post-LASIK.

RESUMOObjetivo: Mostrar os resultados visuais e refracionais com lente intra-ocular multifocal difrativa apodizada. Métodos: Estudo de 100 olhos de 50 pacientes com catarata, submetidos à facoemulsificação com implante bilateral de lente intra-ocular (LIO ) multifocal difrativa apodizada. Foi avaliada a acuidade visual binocular sem e com correção para longe e perto, a previsibilidade refracional e a freqüência de uso de óculos.Resultados: A acuidade visual sem correção para longe foi de e "20/30 em 97,56% dos olhos operados e e" J2 em 100%, sendo que 82% dos pacientes nunca usam óculos e 16% usam de forma esporádica.Conclusão: A LIO multifocal difrativa apodizada mostrou ser uma opção previsível, reproduzível e segura na correção dos vícios de refração para longe e perto durante a cirurgia da catarata, permitindo elevado índice de independência ao uso de óculos.

“…In this regard, monofocal intraocular lens (IOL) usually provides excellent visual function; however, its limited depth of focus does not allow simultaneous clear vision for both distance and near. On the other hand, multifocal (MF) IOLs have multiple focal lengths within the optical zone, which results in a more acceptable range of near through distance vision as well as increased spectacle independence [2,3]. Consequently, MF IOLs are becoming an increasingly popular option for the correction of presbyopia.…”

The impact of multifocal intraocular lens in retinal imaging with optical coherence tomography

et al. 2014

Multifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT). Cross-sectional study conducted at the Refractive Surgery Department of Central Lisbon Hospital Center. Twenty-three eyes of 15 patients with a diffractive MF IOL and 27 eyes of 15 patients with an aspheric monofocal IOL were included in this study. All patients underwent OCT macular scans using Heidelberg Spectralis Ò . Macular thickness and volume values and image quality (Q factor) were compared between the two groups. There were no statistically significant differences between both groups regarding macular thickness or volume measurements. Retinal OCT image quality was significantly lower in the MF IOL group (p \ 0.01). MF IOLs are associated with a significant decrease in OCT image quality. However, this fact does not seem to compromise the accuracy of spectral domain OCT retinal measurements.

Prospective visual evaluation of apodized diffractive intraocular lenses

Abstract: The AcrySof ReSTOR IOL and AcrySof Natural ReSTOR IOL provided good visual performance at distance and near under photopic and mesopic conditions. Intermediate vision with both models was reduced compared with distance and near vision.
