After cataract removal by phacoemulsification, all patients were implanted with TFNT00; follow-up duration varied from 3 to 12 months according to the studies’ design. Binocular defocus curve; absolute manifest refraction spherical equivalent (MRSE); and binocular photopic uncorrected and corrected visual acuities at distance (UCDVA, BCDVA; 4– 5 m), intermediate (UCIVA, DCIVA; 60– 66 cm), and near (UCNVA, DCNVA; 40 cm) were measured.Results: The study included 557 patients, 547 of whom were implanted bilaterally with the TFNT00 IOL (n = 1094 eyes). Binocular visual data at 1 month and 3– 6 months after implantation were available for up to 546 and 542 bilaterally implanted patients, respectively. A co
