Abstract Details


To evaluate the visual acuity for distance, intermediate and near vision as well as contrast sensitivity after implantation of a new hydrophobic asymmetric-refractive extended depth of focus (EDOF) IOL.


All implantations and follow-ups were performed at the AUGENTAGESKLINIK Lockwitzgrund in Dresden, Germany


This prospective analysis comprises 3 month post-op results after binocular implantation of the new asymmetric-refractive EDOF IOL Acunex Vario (Teleon Surgical B.V.) in 20 patients. Results for subjective refraction, uncorrected and corrected visual acuity for distance, intermediate (80cm) and near (40cm) were measured. Mesopic and photopic contrast sensitivity were documented.


Post-op uncorrected distance and intermediate acuity were 0.2 logMAR or better for all patients. Near visual acuity was at least 0.4 logMAR or better in all cases. All eyes were within +/-0.5 D deviation from target SE. The evaluations regarding contrast sensitivity shows mean logCS values > 1.0 for spatial frequencies 1.5, 3, 6 and 12 cpd under photopic and mesopic light conditions without glare and for photopic light conditions with glare.


Patients can benefit from EDOF for far and intermediate distances with the Acunex Vario IOL. Contrast and predictability was excellent and comparable with monofocal IOLs.
