Visual and Refractive Outcomes After Bi-aspheric Trifocal Toric Diffractive Intraocular Lens Implantation

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Vision Science

Background:

• Cataract surgery is a common procedure to restore vision.
• Intraocular lenses (IOLs) are implanted to replace the clouded natural lens.
• Advancements in IOL technology aim to improve visual outcomes and reduce spectacle dependence.

Purpose of the Study:

• To evaluate the clinical performance of the Asqelio Trifocal Toric intraocular lens (IOL).
• To assess visual acuity at distance, intermediate, and near after cataract surgery.
• To determine the refractive accuracy and rotational stability of the implanted IOL.

Main Methods:

• Thirty patients received bilateral implantation of the Asqelio Trifocal Toric IOL.
• Postoperative evaluation included visual acuity measurements (UDVA, CDVA, UIVA, CDIVA, UNVA, CDNVA).
• Defocus curves, contrast sensitivity, IOL rotation, and patient-reported outcomes (questionnaires) were assessed.

Main Results:

• Excellent binocular corrected visual acuities were achieved at all distances.
• High refractive accuracy was noted, with most eyes within 0.50 D of the target refraction.
• The IOL demonstrated significant rotational stability, and contrast sensitivity remained within normal limits.
• Patient satisfaction was high, with minimal reported difficulty in daily activities.

Conclusions:

• The Asqelio Trifocal Toric IOL provides favorable clinical outcomes for cataract surgery patients.
• The IOL offers excellent visual performance across multiple distances and precise refractive results.
• High patient satisfaction and good rotational stability support the use of this IOL.
