This study aimed to evaluate the quality of life and the satisfaction level of Brazilian and Chinese patients who underwent cataract surgery for Acysof IQ PanOptix Model TFNT00 (Alcon Laboratories, Fort Worth, TX, USA) implantation. This retrospective study enrolled 51 patients from China and 51 patients from Brazil. At the 3-month follow-up, uncorrected distance visual acuity (UDVA) at 5 m, uncorrected intermediate visual acuity (UIVA) at 60 cm, and uncorrected near visual acuity (UNVA) at 40 cm were evaluated; Catquest 9SF and the Near Activity Visual Questionnaire (NAVQ) were administered to the patients. The results revealed that the Brazilian patients gained better UDVA and UNVA (p < 0.001), while the Chinese patients gained better UIVA (p = 0.001). With regards to the patients' overall satisfaction with their current vision, the Brazilian patients scored higher (p = 0.002). In situations related to distant and near vision, the Brazilian patients scored higher, while in situations related to intermediate vision, the Chinese patients scored higher. No differences were found between the gender or age subgroups, but the normal axial length (AL) subgroup showed the highest level of satisfaction (p = 0.002). The patients implanted with TFNT00 IOL obtained excellent objective and subjective outcomes in both cultures. The Brazilian patients showed higher satisfaction with their distant and near vision, while the Chinese patients were more satisfied with their intermediate vision.
