Clinical Performance of the Asqelio™ Trifocal Diffractive Intraocular Lens

Clinical Performance of the Asqelio™ Trifocal Diffractive Intraocular Lens

The goal of this observational study is to evaluate whether the Asqelio™ Trifocal intraocular lens (IOL) can improve refractive outcomes and optical quality in patients (aged ≥45 years) undergoing cataract surgery or clear lens exchange, including both male and female participants. The main questions it aims to answer are:

• Does the Asqelio™ Trifocal IOL provide accurate refractive correction with minimal residual refractive error?
• Does the lens reduce light distortion and provide good visual acuity at multiple distances (far, intermediate, near)?

Researchers will not use a comparison group, as this is a post-marketing, single-arm observational study.

Participants will undergo bilateral implantation of the Asqelio™ Trifocal IOL during cataract or lens replacement surgery and attend a study follow-up exam approximately 270±90 days post-surgery.

Complete evaluations including:

• Manifest refraction testing
• Uncorrected and corrected visual acuity at far, intermediate, and near distances
• Binocular defocus curve analysis
• Contrast sensitivity testing
• Light distortion analysis using a Light Distortion Analyzer
• Patient-reported outcomes via the Catquest-9SF and visual symptoms questionnaires.

• Patients 50 years of age or older undergoing cataract surgery by phacoemulsification and binocular IOL implant AsqelioTM Trifocal TFLIO130C
• Independence of use of glasses after surgery.
• IOL power between +5.0D and +34.0D
• Transparent intraocular media except for cataracts in both eyes.
• Potential postoperative visual acuity of 20/25 or better.
