Visual Performance Of A Non-Diffractive Extended Depth Of Focus Intraocular Lens.

To evaluate monocular and binocular visual performance of a new non diffractive extended depth of focus (EDoF) intraocular lens (IOL) using a wavefront shapping technology.

Department of ophthalmology, Hopital de la Citadelle, Liege, Belgique

In a prospective, non-randomized, single-armed, single-center, open-label study, we evaluate 60 eyes from 30 consecutive patients who received bilateral implantation of a non diffractive EDoF IOL (Acrysof IQ Vivity) were included. We evaluated monocular and binocular best corrected distance visual acuity and uncorrected visual acuity. We measured monocular and binocular distance corrected and uncorrected intermediate and near visual acuity. Monocular defocus curve and monocular contrast sensitivity were also evaluated.

60 eyes from 30 consecutive patients were included. Mean subjective spherical equivalent was -0.21.

Binocular distance corrected visual acuity at distance (6m), intermediate (66 cm) and near (40cm) were -0.10 logMAR, 0.14 logMAR, 0.37 logMAR, respectively.

Monocular distance corrected visual acuity at distance, intermediate and near were -0.08 logMAR, 0.22 logMAR, 0.49 logMAR, respectively.

Binocular and monocular uncorrected visual acuity at distance, intermediate and near were -0.04 logMAR, 0.15 logMAR, 0.32 logMAR and  -0.01 logMAR, 0.21 logMAR, 0.43 logMAR, respectively.

Defocus Curve remained above 0.09 logMAR up to a defocus of -1.5 and above 0.25 logMAR up to a defocus of -2. 

This nondiffractive EDoF IOL provides a good visual acuity and visual quality at far and intermediate distance with functional near visual acuity. Patients experienced a high spectacle independent and satisfaction.
