Comparison of visual performance between monofocal and multifocal intraocular lenses of the same material and basic design

Abstract

To compare the visual performance of a monofocal intraocular lens (IOL) (ZCB00) and a multifocal IOL (ZMB00) of the same material and basic design, we evaluated postoperative parameters at 10 weeks after the last surgery in cataract patients who underwent bilateral ZCB00 or ZMB00 implantation from December 13, 2010, to July 29, 2019, with the right and left lenses implanted within 3 months of each other. The study enrolled 2,230 eyes of 1,115 patients. The monofocal group comprised 904 eyes of 452 patients (72.3 ± 6.8 years; females/males, 268/184), and the multifocal group comprised 1,326 eyes of 663 patients (67.0 ± 7.8 years; females/males, 518/145). Contrast sensitivity (4.0/2.5/1.6/1.0/0.7 degrees), contrast sensitivity with glare (1.6/1.0/0.7 degrees), and the VFQ-25 score for driving at night were significantly better in the monofocal group (p < 0.00068, Wald test). Uncorrected intermediate/near visual acuity and near spectacle independence were significantly better in the multifocal group (p < 0.00068, Wald test). The two IOL groups had different characteristics in terms of contrast sensitivity, night-time driving, uncorrected intermediate/near visual acuity and near spectacle independence.

Analysis of Korean Retinal Specialists’ Opinions on Implanting Diffractive Multifocal Intraocular Lenses in Eyes with Underlying Retinal Diseases

“…Because patients with macular disease often complain of unsatisfactory vision related to decreased contrast sensitivity despite objectively good visual acuity [ 2 ], the implantation of an MF-IOL, which can also reduce contrast sensitivity, into an eye with macular disease is considered a relative contraindication considering the possible synergistic effect of the two conditions [ 11 , 12 , 13 , 14 ]. However, given that the risk factors for retinal diseases and cataracts overlap considerably, it is unsurprising that these two diseases occur together frequently in the elderly population [ 15 ].…”

“…Patients with macular disorders, such as age-related macular degeneration (AMD) or central serous chorioretinopathy (CSC), often complain of unsatisfactory vision quality due to reduced contrast sensitivity despite objectively good vision [ 2 ]. Macular disease is known as a relative contraindication for MF-IOL implantation, considering the possible synergistic effect of both conditions on reducing contrast sensitivity especially under low-illumination conditions and the increased long-term risk of developing late-stage, age-related maculopathy after cataract surgery [ 11 , 12 , 13 , 14 ]. However, the clinical outcomes of MF-IOL implantation in eyes with retinal diseases, including macular disorders, have not been sufficiently studied, and there are no evidence-based guidelines for the implantation of MF-IOLs regarding the type and severity of retinal disease.…”

Comparative analysis of a presbyopia-correcting intraocular lens that combines extended depth-of-focus and bifocal profiles with a standard monofocal intraocular lens

“…Since the release of ZFR00, clinical outcomes have been reported with this IOL alone [6][7][8], or in comparison with other presbyopia-correcting IOLs [9,10]. However, no studies have compared the ZFR00 to a standard monofocal IOL (ZCB00: Johnson & Johnson Vision, Santa Ana, CA, USA) of the same material and basic design, which is the most widely implanted worldwide [11,12]. This study compared the clinical results of both IOLs.…”

Geometric-phase intraocular lenses with multifocality

“…These disadvantages may decrease quality of vision, especially in mesopic and scotopic conditions. In particular, the diffusive stray light may lower contrast sensitivity to faint objects and often causes embarrassing halos, glares, and starburst-like optical noises on retina, which are subject to an additional postoperative adaptation period or permanent blurry vision for high spatialfrequency objects [15][16][17] .…”
