Abstract

Relevance. Some of the most current intraocular lenses (IOL) are lenses with an extended depth of focus. Lenses of this type allow you to reduce dependence on glasses by distributing light energy to long-range and focus at medium distance, without losing the quality of vision. Studies that analyze the results of implantation of this type of lens are few. Purpose: to evaluate the clinical outcomes of extended depth of focus (EDOF) intraocular lens (IOL) implantation. Materials and methods. Prospective randomized study enrolled 61 patients of 79 eyes (18 to 86 years) undergone uncomplicated phacoemulsifi cation with EDOF IOL Tecnis Symfony (USA) implantation. The study was conducted from November 2020 through November 2022. Uncorrected near visual acuity (UNVA); corrected near visual acuity (CNVA) and uncorrected and corrected distance visual acuity (UDVA and CDVA), monocular defocus curve and refractive outcomes were evaluated during a 3-month period. When calculating the IOL, the target spherical equivalent was –0.35 ± 0.11 D. Results. In the postoperative period 3 months, visual acuity were 0.7 or better in 82.4% UCDVA, 100% CDVA and 50% UCNVA. 3 months after surgery, UDVA and UNVA at 40 cm averaged 0.85 ± 0.15 and 0.69 ± 0.18, respectively. CDVA and CNVA at 40 cm was 0.98 ± 0.04 and 0.8 ± 0.14, respectively. A total of 85.7% of eyes achieved postoperative visual acuity about 0.5 for the range of defocus levels between +1.00 and −1.50 D. Conclusions. Cataract surgery with Tecnis Symfony EDOF IOL implantation provide functional levels of visual acuity in distance, intermediate zones. The near visual performance with this IOL might be signifi cantly enhanced using a micro-monovision approach
