Comparing an Advanced Monofocal With a Non-diffractive Extended Depth of Focus Intraocular Lens Using a Mini-Monovision Approach

PURPOSE: To compare interindividual differences in visual performance of an advanced monofocal with a nondiffractive extended depth of focus intraocular lens (IOL) using a mini-monovision approach. DESIGN: Single-center, randomized, controlled, double-masked study. METHODS: In total, 48 patients (96 eyes) with bilateral age-related cataract were enrolled. One group received an advanced monofocal IOL RAO200E (RayOne EMV; Rayner) and the other group a non-diffractive extended depth of focus IOL DFT015 (Acrysof IQ Vivity; Alcon) in both eyes. Target refraction for both groups was mini-monovision. After 3 months, monocular and binocular distance corrected and uncorrected distance (CDVA/UDVA), intermediate (DCIVA/UIVA), and near visual acuity (DCNVA/UNVA); contrast sensitivity; binocular defocus curves; halometry; and Quality of Vision questionnaire scores were compared. RESULTS: Binocular mean CDVA, DCIVA at 66 cm, and DCNVA at 40 cm were -0.10±0.10, 0.15±0.11, and 0.32±0.16 logMAR for the RAO200E and -0.10±0.10, 0.12±0.10, and 0.27±0.16 logMAR for the DFT015, respectively, with no significant difference. A significant difference could be shown for the dominant eye in monocular DCIVA and DCNVA and for the dominant and nondominant eye in monocular UNVA, with 0.28±0.14, 0.48±0.22, 0.46±0.21, and 0.41±0.20 logMAR for the RAO200E and 0.14±0.10 (P = .023), 0.35±0.16 (P = .008), 0.30±0.14 (P = .001), and 0.21±0.10 (P = .003) logMAR for the DFT015, respectively. Significantly smaller halo size in the RAO200E group and significantly better distance-corrected defocus curve at -2.5 (P = .031), -2.0 (P = .03), and -1 diopters (P = .03) of defocus in the DFT015 group could be shown. CONCLUSIONS: Distance corrected or uncorrected binocular visual acuity for far, intermediate, and near distance between the advanced monofocal IOL RAO200E and the non-diffractive extended depth of focus IOL DFT015, when compared in a mini-monovision setting, showed no significant differences.
