Visual Quality and Performance of Eyes With Asqelio™ EDoF Toric Lenses

Cataract surgery is one of the most common procedures worldwide, typically involving the replacement of the cloudy natural lens with an intraocular lens (IOL). Traditional monofocal IOLs correct vision for a single distance but do not address intermediate or near vision, leading to dependence on glasses. The Asqelio™ EDOF Toric IOL is designed to provide extended depth of focus, smoother transitions across distances, and astigmatism correction, potentially enhancing overall visual quality and reducing the need for glasses.

This study compares the optical performance and patient outcomes of the Asqelio™ EDOF Toric IOL with those of monofocal IOLs. Key measures include optical quality, visual acuity at multiple distances, refractive correction, and patient-reported satisfaction. Results will be collected during a three-month postoperative follow-up. The findings aim to inform the effectiveness of the Asqelio™ EDOF Toric IOL in improving visual outcomes and quality of life for patients.
