Postoperatively, visual acuity was evaluated at various distances, including 40 cm and 33 cm, for both monocular and binocular outcomes. Patient satisfaction was evaluated using the VF-14 questionnaire.Results: 72 eyes underwent PanOptix IOLs implantation, and 18 eyes received PanOptix toric IOLs. At 3-month postoperative mark, the mean monocular UDVA, UIVA, and UNVA at 40 cm and 33 cm were − 0.02± 0.09, 0.00± 0.07, 0.02± 0.07, and 0.07± 0.14 logMAR, respectively, with proportions of visual acuity exceeding 0.1 logMAR were 96.7%, 96.7%, 94.4%, and 74.4%, respectively. The mean binocular UDVA, UIVA, and UNVA at 40 cm and 33 cm were − 0.05± 0.06, − 0.03± 0.05, 0.00± 0.05, and 0.04± 0.07 logMAR, respectively, with proportions of visual acuity exceeding 0.1 logMAR were 97.8%, 100.0%, 100.0%, and 91.1%, respectively. When the near point shifted from 40cm to 33cm, some patients showed a decline for UDVA, but the average reduction was less than one line. The overall VF-14 questionnaire score was 4.02± 4.19.Conclusion: PanOptix can provide Chinese patients with a full range of satisfying visual acuity, near to 33cm. Though the visual acuity of some patients at 33 cm did not match the level at 40 cm, the gap of one line may not carry clinical significant.Keywords: trifocal IOL, PanOptix, visual acuity at 33 cm
