Clinical Outcomes of a Trifocal Versus an Extended Depth of Field Intraocular Lens in Chinese Patients With Cataract: A Prospective Cohort Study.

To compare the standard outcomes between the PanOptix and Symfony multifocal intraocular lenses (MIOLs) in Chinese patients. This prospective observational cohort study enrolled patients with cataracts between April 2021 and December 2021 at Xiamen Eye Center Affiliated to Xiamen University. The patients were grouped in the PanOptix (TIOL group) and Symfony (EDF group) according to the IOLs implanted. Uncorrected distant, corrected distance, binocular uncorrected intermediate, and near visual acuity (UNVA), distance-corrected intermediate and near VA (DCNVA) , defocus curve, spectacle independence, contrast sensitivity (CS), and visual disturbances were evaluated after 3 months. Forty patients (80 eyes) were enrolled in the study (20/group). Three months after the operation, UNVA (0.13 ± 0.16) and DCNVA (0.08 ± 0.08) were better in the TIOL group than in the EDF group (0.22 ± 0.08 and 0.22 ± 0.08, respectively, =0.003 and < 0.001, respectively). The TIOL group achieved a better-than-0.15-logMAR VA from +0.5 D to -2.5 D (40 cm). VAs of the TIOL group from -1 D (100 cm) to -4 D (25 cm) were better than in the EDF group ( < 0.05). There were no significant differences in the intermediate and far vision outcomes ( > 0.05). Total near-vision spectacle independence was higher in the TIOL group (80%) than in the EDF group (50%) (=0.039). Compared with EDF, TIOL leads to better near-vision outcomes without significant differences for intermediate and distant vision outcomes. ClinicalTrials.gov identifier: ChiCTR2100044558.
