Clinical Performance and Optical Quality of a Non-Diffractive Extended-Depth-of-Focus Intraocular Lens in Patients Undergoing Cataract Surgery or Refractive Lensectomy

<b>Objectives:</b> To evaluate the clinical performance and optical quality of a non-diffractive extended-depth-of-focus (EDOF) intraocular lens (IOL), Asqelio™ EDOF (models ETLIO130C/ETPIO130C), in patients undergoing cataract surgery or refractive lensectomy. <b>Methods:</b> This prospective observational, case-control study included patients bilaterally implanted with either the Asqelio™ EDOF IOL (Study Group) or the spherical monofocal TECNIS^® 1-Piece ZCB00 IOL (Control Group). The postoperative outcomes-at 3 months after surgery-included visual acuities at multiple distances, refraction, contrast sensitivity, the optical scatter index (OSI), wavefront aberrations, and patient-reported outcomes (Catquest-9SF and a quality-of-vision questionnaire). <b>Results:</b> Twenty-three patients (46 eyes) in the Asqelio™ EDOF group and 17 patients (34 eyes) in the monofocal control group were enrolled. Postoperatively, 91% of eyes in the EDOF group were within ±0.50 D of the intended spherical equivalent. The binocular uncorrected distance, intermediate, and near visual acuities were 0.00 ± 0.09, 0.13 ± 0.12, and 0.32 ± 0.15 logMAR, respectively. Contrast sensitivity and OSI values were similar between the study and control groups (<i>p</i> > 0.05). Higher-order aberrations were significantly lower in the EDOF group (<i>p</i> < 0.001), but values in both groups were clinically low. No adverse events were reported. Most patients expressed high satisfaction and reported few visual disturbances. <b>Conclusions:</b> The Asqelio™ EDOF IOL provided good refractive predictability, effective uncorrected vision across distance and intermediate ranges, and high patient satisfaction. Contrast sensitivity and optical scatter were comparable to monofocal implants. This lens can be considered a valuable option for patients seeking an extended range of functional vision with minimal side effects.
