“…Herein, the proportion of eyes implanted with Vivity that achieved a residual refractive error of ±0.5 D of emmetropia was 91.7%, whereas in studies by Gundersen et al and Kohnen et al those proportions were 90% and 90.6%, respectively. 11,12 Refractive outcomes with the enVista IOL in this study were significantly improved compared with those reported in the previous literature. Herein, the proportion of eyes implanted with enVista that achieved a residual refractive error of ±0.5 D of emmetropia was 94.4%, whereas in a study by Heiner et al, this proportion was about 65%.…”

“…In the construction of the lens, two zones can be distinguished: the transition zone 1 is responsible for stretching the wave front and creating a continuous elongated focus, while the transition zone 2 is responsible for shifting the wave front from hyperopia to short-sighted in order to use all the light energy. It has 1.5 D defocusing and negative asphericity of the anterior surface (−0.2 μm) [ 10 , 11 , 12 ]. Moreover, the extended depth of focus, such as that seen in the Vivity lens, can “forgive” the imperfection of IOL power selection caused by the difficulty in calculating IOL power (especially in patients who have undergone refractive surgery in the past) [ 10 ].…”

Purpose: To evaluate postoperative outcomes, spectacle dependance and the occurrence of the photic phenomena in patients after cataract surgery following the implantation of a non-diffractive extended depth of focus (EDOF) intraocular lens was compared to monofocal and multifocal lenses. Methods: We enrolled patients with bilateral cataracts who wanted to reduce their dependence on glasses in the study. They were followed for 6 months. The study group in which the EDOF lens was implanted consisted of 70 eyes in 35 patients. The control groups consisted of: 52 eyes in 26 patients in whom a multifocal was implanted and 52 eyes in 26 patients with implanted monofocal lens. After a total of 2 weeks, 2 months and 6 months post-surgery the following were evaluated: uncorrected and corrected visual acuity at 4 m, 80 cm, 40 cm, manifest refraction expressed as mean refractive spherical equivalent (MRSE), contrast sensitivity, intraocular pressure. A questionnaire on independence from ocular correction, the occurrence of photic phenomena, and patient satisfaction was also completed. Results: Monocular and binocular visual acuity and MRSE 6 months after the procedure were compared between three groups. All of the main analyses, except for comparisons of uncorrected distance visual acuity (both monocular and binocular) level, were significant. Contrast sensitivity was lower among patients with multifocal lens than among patients with EDOF lens. Halo and glare after 6 months were seen more often among patients with multifocal lens than among patients with the other lens (65% of eyes with multifocal lens vs. 6% of eyes with EDOF lens and 0% of eyes with monofocal lens). Glasses were needed by 35% of patients with EDOF lens, and by 96% of patients with monofocal lens and in none of the patients with multifocal lens. Conclusions: Most patients qualify for the implantation of a non-diffractive EDOF lens. Post-operative visual acuity improves at any distance. The best monocular visual acuity for intermediate distances is provided by an EDOF lens, and for near distance by a multifocal lens. The EDOF lens definitely increases independence from spectacle correction compared to monofocal lenses; however, the greatest degree of independence from spectacles is provided by multifocal lenses. The incidence of photic phenomena is slightly higher than that of a monofocal lens, and much lower for a multifocal lens.

“…Results appear slightly better than those recently reported (using the same questionnaire and reporting methodology) for a primary EDOF lens with a wavefront shaping technology incorporated. 27 , 28 They also appear better than reported for a diffractive EDOF lens with a different design, again using the same questionnaire and reporting methodology. 29 …”

Purpose To evaluate the range of vision, visual function, and quality of vision after implantation of a secondary extended depth of focus intraocular lens (EDOF IOL) implanted in the sulcus. Setting One clinical practice in Haugesund, Norway. Design Prospective single arm non-interventional study. Methods Eligible subjects presenting for surgery, or who had previous successful primary cataract or refractive lens exchange surgery in both eyes were subsequently implanted with the AddOn® secondary EDOF IOL in the sulcus. Manifest refraction and visual acuity at distance, intermediate and near were measured 3 months after surgery, along with the monocular defocus curve. Subjects also completed a visual function and a quality of vision questionnaire. Results The study included 32 eyes of 16 subjects. At 3 months postoperative, the mean refraction spherical equivalent (MRSE) was −0.16 ± 0.30 D, with a residual cylinder of 0.29 ± 0.27 D. The mean monocular uncorrected VA was 0.1 logMAR (20/25) or better at all test distances. The monocular defocus curves showed a depth of focus of 2.0 D. For every category except reading fine print, all but one subject (94%) had no difficulty or little difficulty with near tasks. Glare and halos were the most common visual disturbances, with no reports of starbursts. There was no evidence of any intralenticular opacification in any of the eyes, and no evidence of iris chafing/depigmentation. Conclusion This secondary EDOF IOL provided excellent distance and intermediate vision, and very good near vision to subjects. Subject reported near visual function was also very good and visual disturbances were limited. This lens appears to be a good option for patients who would like to improve their range of vision. Results appear as good or better than those reported for primary EDOF lenses.
