Purpose

To evaluate visual performance and patient-reported outcomes after bilateral implantation of new non-diffractive wavefront shaping extended depth of focus (EDOF) intraocular lens (IOL).

Setting

Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Methods

Patient population: We included 16 patients (32 eyes) who received bilateral implantation of a non-diffractive wavefront shaping EDOF IOL (AcrySof® IQ Vivity®, Alcon Research, TX, USA). Target refraction in both eyes was emmetropia.

Observation procedure: Monocular and binocular uncorrected (UCVA) and distance-corrected (DCVA) visual acuity (VA), refractive outcome, defocus curve, contrast sensitivity (CS) were evaluated 3 months after surgery with a questionnaire on optical phenomena and spectacle independence.

Main Outcome measure: Three months postoperative monocular and binocular UCVA and DCVA (logMAR); defocus curve; CS; and quality of vision (QoV) questionnaire results.

Results

Mean spherical equivalent was -0.16 ± 0.37 D 3 month postoperatively. Binocular UDVA at distance, intermediate, and near was 0.01 ± 0.05 logMAR at 4m, 0.05 ± 0.05 logMAR at 80cm, 0.07 ± 0.06 logMAR at 66cm, and 0.25 ± 0.11 logMAR at 40cm, respectively. Despite some minor optical phenomena, 88% of patients would choose the same lens. 63% of patients reported no optical phenomena at all. Contrast sensitivity was 1.25 ± 0.41 logCS (photopic), 0.96 ± 0.24 logCS (mesopic) and 0.93 ± 0.24 (mesopic + glare).

Conclusion

This non-diffractive wavefront shaping EDOF IOL provides good VA at far and intermediate distance and functional near VA. It showed good QoV and CS, and high spectacle independence for distance and intermediate vision with significantly less optical phenomena than with other EDOF or MIOLs.
