Evaluation of Evolux™ Intraocular Lenses in Cataract Surgery: Clinical Outcomes and Patient Satisfaction

Abstract

Objective: This study aimed to evaluate the initial clinical outcomes of and patient satisfaction with the newly introduced extended monofocal Evolux™ intraocular lens following cataract surgery. Methods: A retrospective study was conducted, involving 18 patients (36 eyes) who received Evolux™ lenses bilaterally. The inclusion criteria comprised individuals over 40 years old with no active eye diseases, excluding cataracts, and no postoperative complications. Various parameters were evaluated, including distance, intermediate, and near visual acuity; refraction; defocus curves; dependency on spectacles; and patient satisfaction. Patient satisfaction and visual quality of life were measured using the Catquest-9SF and QOV questionnaires. Results: The average age of the patients was 72.7 years, with the majority being women (77.8%). The results demonstrated excellent postoperative visual acuity at different distances. The mean logMAR values for uncorrected visual acuity were −0.04 for distance vision, 0.15 for intermediate vision, and 0.35 for near vision. The defocus curve indicated good tolerance, with visual acuity exceeding 20/20 in significant defocus ranges. Most patients expressed high satisfaction with their vision without spectacles, particularly for distance and intermediate vision. The need for spectacles for near vision was notably reduced. Furthermore, there was a low incidence of photic phenomena like halos and glare, contributing to the overall high patient satisfaction. Conclusions: Evolux™ lenses were found to be an effective choice for cataract surgery, providing excellent visual acuity at various distances and high patient satisfaction.
