Early Functional Results Of A New Non-Diffractive Extended Monofocal Iol

Improving intermediate vision means to improve patients everday life activities. Demand for activities like tablet/PC work, driving and exercising is rising due to a more active aging population, with the tendency to work beyond retirement age and an overall higher interest in good visual acuity with minimal side effects. In this ongoing study we evaluated the clinical outcomes of an extended aspheric monofocal non-diffractive IOL (Evolux 1110ACH, SIFI, Lavinaio, Italy) with regards to an improved intermediate vision while aiming to provide comparable distance vision to standard monofocal IOLs.

The first results of this ongoing clinical study include 8 patients who underwent phacoemulsification due to cataract with implantation of the IOL Evolux 1110ACH (SIFI, Lavinaio, Italy). Subjective refraction, Halo and Glare Simualtion, corrected and uncorrected visual acuity (VA), monocular and binocular [logMar] for distance, intermediate and near vision, as well as a best-corrected defocus curve analysis were evaluated 1 (n=7) and 3 (n=4) months after surgery.

Mean binocular visual acuity in logMAR at 1/3 months were UDVA -0.04/-0.06; UIVA 0.07/0.11; UNVA 0.26/0.28; CDVA -0.06/ -0.10 (±0.07); DCIVA 0.04/0.09; DCNVA 0.25/ 0.30. The binocular distance-corrected defocus curve at 1 months showed a continuous visual acuity of 0.16 or better in the range of +0.50 to -1.50 diopters of defocus. After 3 months a continuous visual acuity of 0.03 or better was shown in the range of +0,5 to -1.5 diopters of defocus

The initial results indicate good visual acuity at far and intermediate distances as well as a wider range of defocus. The patients mainly reported little to none photic phenomena regarding the halo and glare simulation. Evaluation of visual acuity outcomes at 3 and 6 months postoperatively is ongoing.
