Abstract
To compare visual and contrast sensitivity (CS) outcomes, reading skills, and spectacle independence in patients implanted with two models of trifocal intraocular lenses (IOLs) or an extended range of vision (ERV) IOL. This non-randomized prospective series of cases included 120 eyes of 60 patients undergoing cataract surgery with bilateral implantation of three different IOLs: the ERV IOL Tecnis Symfony (40 eyes) (Abbott Medical Optics), the trifocal IOLs PanOptix IQ (40 eyes) (Alcon), and AT LISA tri 839MP (40 eyes) (Carl Zeiss Meditec). Visual results, photopic and mesopic CS, binocular reading skills (MNREAD charts), and patient satisfaction were evaluated 3months after surgery. There was no statistically significant difference between groups regarding uncorrected and corrected distance visual acuity. The Tecnis Symfony IOL showed better mesopic intermediate visual outcomes than the two trifocal IOLs (p < 0.05 vs AT LISA). Under photopic conditions, AT LISA tri 839MP and PanOptix IQ showed better near visual outcomes compared with the ERV IOL (p < 0.05 to p < 0.001). The Tecnis Symfony IOL provided significantly better photopic and mesopic CS outcomes than the other IOL models (p < 0.001). Reading skills were not significantly different between the three IOL models (p > 0.05). Less patients implanted with the two trifocal IOLs required a near addition than patients with the ERV IOL. All the tested IOLs provided good visual outcome, reading performance, and spectacle independence after cataract surgery. While trifocal IOLs gave better near visual acuity results, the ERV IOL provided better contrast sensitivity.
