Preliminary Clinical Outcomes Of An Enhanced Depth Of Focus Intraocular Lens

Extended Depth of Focus (EDOF or EDF), or Extended Range of Vision, is a new technology that has recently emerged in the treatment of Presbyopia-correcting IOLs. In contrast to multifocal intraocular lenses (IOLs) used in treatment of presbyopia, EDOF lenses work by creating a single elongated focal point to enhance “range of vision” or “depth of focus”. The purpose of this study to evaluate preliminary clinical outcomes and patients satisfaction of the new enhanced depth of focus (EDOF) Lux Smart TM intraocular lens (IOL) in patients who had undergone bilateral cataract surgery.

Cataract surgery and all pre- and postoperative assessments were performed in the “Laser Correction Center” Ophthalmology departement at Shengavit MC, Yerevan, Armenia. All surgical procedures were performed by the same experienced surgeon. The study was conducted according to the criteria set in the Declaration of Helsinki and all patients provided informed consent. 

We conducted randomized study from May 2022 to September 2022. Inclusion criteria were early and immature cataract. Exclusion criteria were other concomitant ocular diseases. 20 patients (40 eyes) underwent bilateral LuxSmart IOL implantation. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm were assessed and presence of photic phenomena were evaluated.

This study shows that new LuxSmart EDOF IOL achieved higher performance for intermediate and near vision, without increasing risk of
dysphotopsias. The study limitation are small sample size and short follow-up time. Therefore, the further research is recommended.
