Refraction, corrected (CDVA) and uncorrected (UDVA) visual acuity of the last available visit were used in the analysis. Intraoperative and postoperative AEs of the cohort were reviewed.Results: A total of 191 eyes of 133 patients with the mean age of 70.2± 11.2 years were included in this study. The mean follow-up time of the last available visit was 1.7± 1.3 months. The mean postoperative monocular UDVA was 0.09± 0.16 logMAR (≈20/25), and 74.9% (143/191) eyes achieved ≥ 20/25 UDVA. The percentage of eyes with manifest spherical equivalent (MSE) within ± 0.50D and ± 1.00D of emmetropia was 84.8% (162/191) and 98.4% (188/191), respectively. Linear regression of attempted vs achieved MSE showed a tight relationship, with the coefficient of determination close to 1 (R2=0.99), indicating a very predictable refractive correction. The reported AEs were those typically expected after cataract surgery. There were no AEs related to intraoperative manipulation with the IOL/injector or to postoperative stability of the IOL in the capsular bag. No eye lost ≥ 2 lines of CDVA.Conclusion: The implantation of CT LUCIA 621P resulted in good refractive predictability and visual outcomes. No IOL-related adverse events were reported.Keywords: monofocal IOL, non-constant aberration-correcting optic design, cataract surgery
