Purpose: To investigate visual and safety outcomes of AcrySof® IQ PanOptix® (model TFNT00), a trifocal, presbyopia-correcting intraocular lens (IOL), in patients of different ethnicities across multiple countries, based on a pooled analysis of six prospective multicenter studies. Patients and Methods: This pooled analysis included adult patients from six prospective clinical studies performed across 56 centers worldwide. 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 continuous range of 0.1 logarithm of the minimum angle of resolution (logMAR) or better vision from distance (0.00 diopter [D], 4–5 m) to near (–3.00 D; optically equivalent to 33 cm) was observed 3–6 months after TFNT00 implantation. At 3–6 months, 88.2% of first eyes achieved an MRSE ≤0.50 D and 88.7% of second eyes achieved an MRSE ≤0.50 D. Overall, 99.3%, 92.3%, and 94.6% of patients bilaterally implanted with TFNT00 achieved binocular photopic BCDVA, DCIVA, and DCNVA of 0.14 logMAR or better, respectively. Ocular adverse device effects and secondary surgical interventions (SSIs) were infrequent. Conclusion: This global pooled analysis showed that TFNT00 provided a continuous range of 0.1 logMAR (~20/25 Snellen) or better vision from distance to 33 cm, with a low incidence of ocular adverse device effects and SSIs.
