| Objectives | |
| Narrative objectives1 | To compare binocular visual outcomes between patients implanted bilaterally with a new trifocal intraocular lens (IOL) and patients implanted with bifocal IOLs having +3.0 diopter (D) near addition power in the dominant eye and +4.0D in the nondominant eye. |

| Assessment | |
| Primary outcomes | 1) Binocular uncorrected and corrected visual acuity (VA) at various distances measured using the all-distance vision tester (KOWA AS-15),
2) Contrast visual acuity (CAT-2000) with and without glare, 3) Near stereoacuity (Titmus stereo test), 4) Number (%) of patients who reported glare and halo symptoms 5) Wavefront higher-order aberrations (HOAs); total, coma-like, and spherical-like HOAs 6) Pupil diameter, corneal astigmatism, manifest spherical equivalent value |

|
| Interventions/Control_1 | A trifocal IOL group (n=32) implanted bilaterally with a new trifocal IOL (Alcon PanOptix; TFNT00). | |
| Interventions/Control_2 | A combined bifocal group (n=46) implanted with a bifocal IOL with +3.0D near addition power (SN60D1) in the dominant eye and +4.0D near addition power (SN60D3) in the nondominant eye. | |

| Key inclusion criteria | All patients who elected to undergo bilateral phacoemulsification and implantation of multifocal IOLs | |||
| Key exclusion criteria | Preoperative exclusion criteria were patients with any pathology of the cornea, macula or optic nerve; opaque media other than cataract; history of ocular inflammation or surgery; corneal astigmatism of 1.0 D or more; marked irregular corneal astigmatism; amblyopia; patients who had participated in another clinical trial; and any difficulties with examinations, analyses, or follow-up. Intraoperative exclusion criteria were a small pupillary diameter that required pupil expansion procedures and eventful surgery. | |||
