Clinical Outcomes And Rotational Stability Of Bi-Aspheric Trifocal Diffractive Toric Intraocular Lens

This study aims to evaluate clinical outcomes post-cataract surgery following bilateral implantation of bi-aspheric diffractive Asqelio™ Trifocal Toric intraocular lens (IOL).

Oftalvist, Alicante, Spain

Thirty patients underwent bilateral implantation and were assessed three months postoperatively. Key measures included refractive error, visual acuities at various distances (photopic: uncorrected and corrected distance, intermediate, and near; mesopic: corrected distance at near), defocus curves, contrast sensitivity under different lighting conditions with and without glare, and IOL rotational stability.

Binocular photopic visual acuities were as follows: CDVA -0.04±0.06, CDIVA 0.02±0.08, CDNVA 0.02±0.07, and mesopic CDNVA 0.22±0.11. All patients achieved cumulative CDVA ≥20/25, and CDIVA and CDNVA ≥20/32. Binocular depth-of-focus was ~3.25D. Mean postoperative spherical equivalent was -0.08±0.26D, with 95% within ±0.50D. Mean postoperative refractive cylinder was -0.22±0.27D, with 91.67% ≤0.50D. IOL rotation averaged 0.25±0.65 degrees, all eyes below 5 degrees. Contrast sensitivity was generally normal under photopic and mesopic conditions, except for 12 cpd under mesopic conditions with glare.

Asqelio™ Trifocal Toric IOL yielded favorable outcomes, providing excellent visual performance, precise refractive results, and remarkable rotational stability.
