Abstract

Abstract : Purpose : To compare the visual acuity, refractive outcomes, and quality of vision in patients with bilateral implantation of 4 intraocular lenses (IOLs). Settings : Department of Neurosciences, Biomedicine and Movement Sciences, Eye Clinic, University of Verona, Verona, and Carones Ophthalmology Center, Milano, Italy. Design : Prospective case series. Methods : The study included patients who had bilateral cataract surgery with the implantation of 1 of 4 IOLs as follows: Tecnis 1‐piece monofocal (monofocal IOL), Tecnis Symfony extended range of vision (extended‐range‐of‐vision IOL), Restor +2.5 diopter (D) (+2.5 D multifocal IOL), and Restor +3.0 D (+3.0 D multifocal IOL). Visual acuity, refractive outcome, defocus curve, objective optical quality, contrast sensitivity, spectacle independence, and glare perception were evaluated 6 months after surgery. Results : The study comprised 185 patients. The extended‐range‐of‐vision IOL (55 patients) showed better distance visual outcomes than the monofocal IOL (30 patients) and high‐addition apodized diffractive–refractive multifocal IOLs ( P ≤ .002). The +3.0 D multifocal IOL (50 patients) showed the best near visual outcomes ( P < .001). The +2.5 D multifocal IOL (50 patients) and extended‐range‐of‐vision IOL provided significantly better intermediate visual outcomes than the other 2 IOLs, with significantly better vision for a defocus level of −1.5 D ( P < .001). Better spectacle independence was shown for the +2.5 D multifocal IOL and extended‐range‐of‐vision IOL ( P < .001). Conclusions : The extended‐range‐of‐vision IOL and +2.5 D multifocal IOL provided significantly better intermediate visual restoration after cataract surgery than the monofocal IOL and +3.0 D multifocal IOL, with significantly better quality of vision with the extended‐range‐of‐vision IOL.
