Visual performance comparison of 2 extended depth-of-focus intraocular lenses

Purpose: To compare the visual acuity and satisfaction outcomes of 2 different concepts of extended depth-of-focus intraocular lenses (EDOF IOLs). Setting: University Eye Hospital Bochum, Germany. Design: Prospective randomized comparative clinical trial. Methods: Patients undergoing cataract surgery with the implantation of 2 different concept EDOF IOLs. In the first group (IC-8 Group), a monofocal 1-piece Tecnis Z B00 IOL (Johnson & Johnson Vision Care, Inc.) was implanted in the dominant eye, and an IC-8 IOL (AcuFocus) was implanted in the nondominant eye. In the second group (Symfony Group), a Tecnis Symfony IOL (Johnson & Johnson Vision Care, Inc.) was implanted in both eyes. The target refraction of the dominant eye was emmetropia and slight myopia (minimonovision, -0.75 diopters) in the nondominant eye. Visual and refractive outcomes and patient satisfaction rates were evaluated 3 months postoperatively. Results: This study comprised 76 eyes of 38 patients. No intraoperative or postoperative complications occurred in either group. Target refraction was reached in both groups without statistically significant differences. The uncorrected distance visual acuity (UDVA, photopic and mesopic light conditions) was excellent in both groups with statistically significantly better results in the IC-8 goup (logarithm of the minimum angle of resolution; IC-8 Group (0.1 +/- 0.07 logarithm of the minimum angle of resolution [logMAR]; Symfony Group 0.07 +/- 0.1 logMAR, P value .02 [photopic]; IC-8 group 0.12 +/- 0.09 logMAR, Symfony group 0.22 +/- 0.1 logMAR, P value < .01 [ mesopic]). Binocular uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) were also good in both groups without statistically significant differences (UIVA: IC-8 Group, 0.01 +/- 0.07 logMAR, Symfony Group 0.01 +/- 0.08 logMAR, P value .35; UNVA: IC-8 Group 0.14 +/- 0.11, Symfony Group 0.09 +/- 0.08, P value .14). Subjective satisfaction was high in both groups. Conclusions: Both EDOF IOLs provided a very good UDVA with superior results in the IC-8 Group, and a good UIVA and UNVA under photopic light conditions. Subjective patient satisfaction was higher in the IC-8 Group. Copyright (C) 2020 Published by Wolters Kluwer on behalf of ASCRS and ESCRS
