The study was done to compare the clinical outcomes of mix-and-match implantation of a diffractive extended depth of focus IOL (TECNIS Symfony ZXR00; Johnson & Johnson Vision) and a diffractive bifocal IOL (TECNIS ZLB00 +3.25 diopters [D]; Johnson & Johnson Vision) and bilateral implantation of a diffractive trifocal IOL (AcrySof IQ PanOptix; Alcon Laboratories, Inc).

This prospective comparative study compares the clinical outcomes of patients with age-related cataract undergoing cataract surgery using the IOLs described. Patients were divided into the mix-and-match group and the trifocal group.

Total number of 50 patients were enrolled. At 6 months postoperatively, outcomes of binocular UDVA, UIVA, and UNVA were similar in both groups. The binocular defocus curve only differed at vergences of −0.50 to −1.00 D (better for the mix-and-match group; P = .032 and .004, respectively) and at −4.00 D (better for the trifocal group; P = .001). Significantly higher reading speeds in the mix-and-match group were measured at 0.7 and 0.5 logMAR (P = .038 and .034, respectively). There were no significant differences between groups for contrast sensitivity and the results of the questionnaire.

The study concluded that mix-and-match implantation seemed to be a good option for patients with high demands for distance and intermediate visual acuity, whereas the trifocal IOL appeared to be more suitable for patients with enhanced near vision demands.
