Abstract Details

Purpose:

The aim of this study was the evaluation of visual quality for far, intermediate and near distances, subjective refraction, contrast sensitivity and defocus performance with a new segmental, refractive extended depth of focus (EDoF) IOL.

Setting:

All surgeries were performed at the Breyer-Kaymak-Klabe Eye Surgery and Premium Eyes in Duesseldorf, Germany, member of the International Vision Correction Research Center (IVCRC.net).

Methods:

40 eyes of 20 patients with cataract and expected postoperative corneal astigmatism of under -0.75 D were included. In all eyes, a new hydrophobic EDoF IOL with 1.5 D addition (Acunex Vario, AN6V; Teleon Surgical B.V., The Netherlands) was implanted. We assessed subjective refraction, monocular and binocular uncorrected and best distance corrected visual acuity for far, intermediate and near distances, contrast sensitivity and binocular defocus capacity after 3 months postoperatively. Halo and Glare phenomena were documented.

Results:

The cumulative spherical equivalent of subjective refraction was within +/-0.5 D for 81% and within +/-1.0 D for 100% of all included eyes. The defocus curve showed significantly better intermediate and near vision compared to monofocal IOL. Halo & glare was less than with diffractive low add IOL. Contrast sensitivity was very similar to other refractive EDoF IOL and monofocal IOL under photopic and mesopic conditions.

Conclusions:

Acunex Vario provides excellent visual outcomes across a wide range of distances from far to intermediate up to 60 cm, with contrast sensitivity and photopic phenomena values comparable with other refractive EDoF IOL, but better than diffractive EDoF IOL. We mainly implant Acunex Vario in the Duesseldorf Formula mode as blended vision (target refraction: in dominant eye emmetropia and in non dominant eye -1.5D). Thus, the patients can see far, work in PC/iPad distance and read usual book- and newspaper print without glasses without suffering from photopic phenomena. However, small print reading is not possible as with diffractive trifocal MIOL.
