Visual Results After Extended Depth-of-Focus Lens Implantation in Patients Undergoing Clear Lens Surgery

Abstract

Background/Objectives: To evaluate the efficacy and visual quality provided by the extended depth-of-focus AcrySof IQ Vivity lens (Alcon Laboratories, Inc., Fort Worth, TX, USA) in patients undergoing refractive lens exchange (RLE) surgery for presbyopia correction. Methods: This descriptive prospective single-arm clinical study included 30 patients (60 eyes) aged 49-69 years (mean 60.2) who underwent clear lens surgery for presbyopia correction. Postoperative 3-month assessments included uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA), distance-corrected intermediate visual acuity (DCIVA), and distance-corrected near visual acuity (DCNVA) measurements. Patient satisfaction and visual disturbances were evaluated using a standardized questionnaire. Results: Postoperative binocular visual acuity results were as follows: UDVA, 0.00 ± 0.06 logMAR; UIVA 0.08 ± 0.07 logMAR; and UNVA, 0.18 ± 0.10 logMAR. Refractive outcomes showed mean spherical equivalent values of -0.15 D ± 0.28 diopters (D) for the right eye and -0.18 D ± 0.30 D for the left eye postoperatively. Most patients (93.2%) were satisfied or very satisfied with the surgery, and 63.3% never needed glasses at any distance postoperatively. Mild and non-disabling photic phenomena were reported by 23% of patients for halos and 30% for glares. Conclusions: The study IOL provides excellent visual acuity for far and intermediate distances, as well as functional near vision under photopic conditions, with high levels of patient satisfaction and minimal visual disturbances. This lens is a promising option for non-cataract patients undergoing RLE for presbyopia correction.
