“…It was reported that asymmetric multifocal IOLs with near addition of + 1.5 D yielded superb distance vision (UDVA of 0.00 logMAR and CDVA of − 0.08 logMAR) in conjunction with good intermediate vision (UIVA at 80 cm of 0.01 logMAR), but near vision was rather limited (UNVA at 40 cm of 0.41 logMAR) [ 2 ]. Another study indicated that Lentis Comfort LS-313 MF15 gave excellent distance and intermediate visual acuity (UDVA of − 0.01 logMAR and UIVA at 70 cm of 0.05 logMAR), while near visual acuity was at a lower level (UNVA at 30 cm of 0.54 logMAR) [ 4 ]. The findings of our study are in good agreement with these previous reports.…”

“…Contrast sensitivity function measured at 6 months postoperatively was within the normal range of age-matched controls. It has been shown that contrast sensitivity of this IOL is similar to that of standard monofocal IOLs [ 4 – 6 ]. Previous studies reported that the level of contrast sensitivity did not differ between extended-range-of-vision IOLs and monofocal IOLs, but these two IOLs exhibited significantly better level of contrast sensitivity than conventional multifocal IOLs with + 2.0 D or + 3.0 D addition [ 15 ].…”

“…It was reported that not many patients complained of disturbing photic symptoms after implantation of the rotationally asymmetric, segmented, refractive multifocal IOL with addition of + 1.5 D [ 1 , 3 , 4 , 6 ]. Yoo et al [ 1 ] compared visual function in eyes with multifocal Lentis comfort LS-313 MF15 (+ 1.5D add) and Lentis M plus LS-313 MF30 (+ 3.0 D add), and exhibited that the former IOL was associated with significantly fewer halo and glare than the latter type.…”

Background To prospectively evaluate surgical results following implantation of rotationally asymmetric, plate-haptic, refractive segmented multifocal toric intraocular lenses (IOLs) with near addition of + 1.5 diopters (D) (Lentis Comfort LS-313 MF15T, Oculentis GmbH). Methods In 59 eyes of 41 patients, ocular examinations were conducted before and 1 day, 1 week, 1, 3, and 6 months after surgery. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected (DCIVA) intermediate visual acuity at 70 cm, and uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity at 30 cm were tested. A defocus curve was drawn, and the degree of disturbing photic phenomena were questioned. Results The IOL showed excellent rotational stability; the average absolute rotation was 1.66 ± 1.17 degrees from 1 day 1 to 6 months postoperatively, and 98.1 and 100% of eyes yielded rotation of less than 5 and 10 degrees, respectively. Postoperative distance and intermediate visual acuity were highly satisfactory; UDVA, CDVA, UIVA, and DCIVA were about 20/20, 20/16, 20/25, 20/25, respectively. Near visual acuity was suboptimal; UNVA and DCNVA were at approximately 20/60. The defocus curve analysis showed that 20/25 and 20/40 uncorrected visual acuity was attained at as close as 60 and 40 cm, respectively. Contrast sensitivity was within a normal range, and subjective photic phenomena were minimum. Conclusions The refractive segmented, rotationally asymmetric multifocal toric IOLs with + 1.5 D near addition showed superb rotational stability and highly satisfactory distance and intermediate vision. Contrast sensitivity was high and incidence of photic symptoms was very low.

“…An extension to this trend are IOL described as 'Extended Depth of Focus' (EDOF). Designs include a low near addition (+1.75 D) (Gatinel and Loicq, 2016) diffractive IOL (Millan and Vega, 2017;Weeber et al, 2015) and asymmetric (+1.50 D) IOL (Pedrotti et al, 2018). The studies hitherto suggest it provides visual benefits across all distances after cataract surgery, with a minimal level of disturbing photic phenomena and high levels of patient satisfaction (Cochener and Concerto Study, 2016;Kaymak et al, 2016).…”

Presbyopia is a global problem affecting over a billion people worldwide. The prevalence of unmanaged presbyopia is as high as 50% of those over 50 years of age in developing world populations, due to a lack of awareness and accessibility to affordable treatment, and is even as high as 34% in developed countries. Definitions of presbyopia are inconsistent and varied, so we propose a redefinition that states "presbyopia occurs when the physiologically normal age-related reduction in the eye's focusing range reaches a point, when optimally corrected for distance vision, that the clarity of vision at near is insufficient to satisfy an individual's requirements". Strategies for correcting presbyopia include separate optical devices located in front of the visual system (reading glasses) or a change in the direction of gaze to view through optical zones of different optical powers (bifocal, trifocal or progressive addition spectacle lenses), monovision (with contact lenses, intraocular lenses, laser refractive surgery and corneal collagen shrinkage), simultaneous images (with contact lenses, intraocular lenses and corneal inlays), pinhole depth of focus expansion (with intraocular lenses, corneal inlays and pharmaceuticals), crystalline lens softening (with lasers or pharmaceuticals) or restored dynamics (with 'accommodating' intraocular lenses, scleral expansion techniques and ciliary muscle electrostimulation); these strategies may be applied differently to the two eyes to optimise the range of clear focus for an individual's task requirements and minimise adverse visual effects. However, none fully overcome presbyopia in all patients. While the restoration of natural accommodation or an equivalent remains elusive, guidance is given on presbyopic correction evaluation techniques.

“… 1–3 Currently, the majority of new generation MIOLs improve these defects and present a diffractive platform that splits lights to the retina, in order to obtain a good quality image at several distances and achieve a good spectacle independence. 4 5 Nowadays, modern MIOLs obtain multifocality, thanks to two different diffractive technologies which are extended range of vision (ERV) that is used by Tecnis Symfony and Enlighten technology (Enlighten Optical Technology) that is exploited by PanOptix. 6 7 Several studies have been carried out on these MIOLs, but the literature present discordant results on visual acuity at intermediate distances, defocus curve and on the quality of vision.…”

ObjectiveTo evaluate objective and subjective outcomes after bilateral implantation of two different multifocal intraocular lenses, which correct pseudophakic presbyopia in an adequate and homogeneous population court.Methods and analysisFifty patients were evaluated at 3 months after bilateral implantation, at the Eye Clinic of University of Verona and at the Carones Ophthalmology Center Milano, as follows: Tecnis Symfony (25 patients), Alcon PanOptix (25 patients). Main outcomes were uncorrected and best-corrected distance visual acuity (UDVA and BCVA) at 4 m, 60 cm (best distance corrected intermediate visual acuity (BDCIVA) and uncorrected intermediate visual acuity), 40 cm (best distance corrected near visual acuity (BDCNVA) and uncorrected near visual acuity (UNVA)), objective refractive outcome, defocus curve, contrast sensitivity (Modulation Transfer Function (MTF) cut-off), optical quality (Strehl ratio), aberrometry (root mean square RMS 4 mm), subjective quality of life (National Eye Institute Refractive Error Quality of Life score (NEI-RQL-42 score) test).ResultsSymfony and PanOptix showed BCVA and UDVA comparable results. Symfony presented significant better outcomes at BDCIVA (p=0.001), while PanOptix showed better performances at BDCNVA and UNVA (p=0.01). Symfony achieved better results in RMS 4 mm (p=0.024) and in MTF cut-off (p=0.041). In the questionnaire NEI-RQL-42, PanOptix presented better scores in ‘near vision’ and ‘spectacles independence’, whereas Symfony in ‘symptoms’ and ‘clarity of vision’.ConclusionBoth intraocular lenses are valid options to avoid pseudophakic presbyopia, even though they present different features which make them unique. Symfony allows patients to achieve a better objective and subjective quality of vision and contrast sensitivity; PanOptix provides better outcomes in near vision and spectacles independence requirements.

Quality of vision, patient satisfaction and long-term visual function after bilateral implantation of a low addition multifocal intraocular lens

Abstract: Our findings indicated that the Comfort IOL +1.5 D provides a good intermediate spectacle independence together with a high quality of vision, with a low amount of subjective symptoms and a contrast sensitivity similar to those obtained with a monofocal IOL.
