Jacksonville, Florida, USA) were included in this prospective study. Postoperative follow-up at 3 months included uncorrected and corrected distance visual acuity (UDVA/CDVA), uncorrected and distance corrected intermediate visual acuity at 80 cm (UIVA/DCIVA), and uncorrected and distance corrected near visual acuity at 40 cm (UNVA/ DCNVA), as well as binocular corrected defocus curve analysis (range +2 to − 4 dioptres), contrast sensitivity under photopic and mesopic conditions (CSV-1000, VectorVision, Greenville, USA) and patient-reported outcome (Heidelberg Daily Task Evaluation (DATE) Questionnaire and halo and glare evaluation).Results: Mean binocular visual acuity in logMAR at 3 months was UDVA/ CDVA (− 0.02/ − 0.07), UIVA/ DCIVA (0.03/ 0.02) and UNVA/ DCNVA (0.16/ 0.16). The defocus curve analysis showed a visual acuity of 0.20 logMAR or better up to − 2.25 D. Contrast sensitivity under photopic and mesopic conditions was within normal age limits. The study IOL was non-inferior to standard monofocal lenses in terms of halo/glare. Eighty-three percent of participants were fully satisfied with the outcome of the IOL implantation and ninty-six percent of patients would repeat the surgery with the same IOL and recommend the IOL to friends or acquaintances.Conclusion: The TECNIS PureSee IOL yielded good visual performance with high patient satisfaction. Patients received a good EDoF-effect with a low probability of disturbing photopic phenomena in terms of halo and glare.Keywords: EDOF, non-diffractive, intraocular lens, simultaneous vision
