Comparison of Visual Performance of Multifocal Intraocular Lenses with Same Material Monofocal Intraocular Lenses

Abstract

PurposeTo compare the visual performance of multifocal intraocular lenses (IOLs) and monofocal IOLs made of the same material.MethodsThe subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00) or Tecnis® multifocal IOLs (ZMA00 or ZMB00) bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patients who were implanted with Tecnis® multifocal IOLs bilaterally. The monofocal group was an age- and sex-matched control group, and included 85 patients who were implanted with Tecnis® monofocal IOLs bilaterally. Lens opacity grading, the radius of corneal curvature, corneal astigmatism, axial length and the refractive status were measured preoperatively. Pupil size, ocular aberrometry, distance, intermediate and near visual acuity, contrast sensitivity with and without glare and the responses to a quality-of-vision questionnaire were evaluated pre- and postoperatively.ResultsThe uncorrected near visual acuity was significantly better in the multifocal group, whereas both the corrected intermediate and near visual acuity were better in the monofocal group. Contrast sensitivity (with and without glare) was significantly better in the monofocal group. The rate of spectacle dependency was significantly lower in the multifocal group. There were no significant differences between the two groups regarding most items of the postoperative quality-of-vision questionnaire (VFQ-25), with the exception that the patients in the monofocal group reported fewer problems with nighttime driving.ConclusionsThe multifocal IOLs used in this study reduced spectacle dependency more so than monofocal IOLs and did not compromise the subjective visual function, with the exception of nighttime driving.

Objective and subjective visual quality after implantation of all optic zone diffractive multifocal intraocular lenses: a prospective, case-control observational study

“…Interestingly, intermediate VA was not impaired in this kind of multifocal IOL. Previous studies showed that with +4.00 D IOLs there is a reduction of intermediate vision, and so +3.00 D IOLs are designed to obtain clear intermediate vision, which can compromise 33 cm near distance vision 1 21. Our results suggested that visual performance was further improved after implantation of ZMB00 IOLs and was consistent with recent report 7 22.…”

“…Multifocal IOL ZMB00 had the same good distance VA as monofocal IOL ZCB00, but much better near VA, which may be because it is pupil-independent, just like previous studies reported 1 2 21. Interestingly, intermediate VA was not impaired in this kind of multifocal IOL.…”

Comparative study on optical performance and visual outcomes between two diffractive multifocal lenses: AMO Tecnis® ZMB00 and AcrySof® IQ ReSTOR® Multifocal IOL SN6AD1

“…As demonstrated in other studies, the good quality of distance and near vision was attested through both types of lenses, regardless of which addition had been used. The improvement in UDVA, in addition to the excellent individual results, for both long and short distance confirmed the efficacy of the treatment and provided independence from glasses (1)(2)(3)6,12,13,17,(21)(22)(23)25) . Such inference is particularly evident when considering postoperative SE.…”

“…The analysis of groups distribution demonstrates homogeneity and enables comparisons between groups, indicating its suitability for comparison to other publications (7,10,(21)(22)(23)(24) . As demonstrated in other studies, the good quality of distance and near vision was attested through both types of lenses, regardless of which addition had been used.…”

“…It must be considered that under photopic and mesopic conditions, the two groups showed averages below their corresponding monofocal IOLs peers, as described in other studies. Considering CS, ZA9003 IOL has been considered better than the ZMA00 IOL (10,22,23) . Nakano et al and Vingolo et al concluded the same by comparing SN60WF and SA60AT IOLs with SN60D3 and ZM900 IOLs (27,28) .…”
