Purpose

To evaluate visual performance, defocus tolerance, optical quality, and patient-reported outcomes 3 months after bilateral implantation of Asqelio Pluris intraocular lens (IOL) (AST VisionCare Inc., USA), a Phase-Ring-based lens within the Enhanced Partial-Depth of Field (DOFi) category.

Setting

IOA Miranza, Madrid, Spain, and Clinica Visióon, Granada, Spain.

Methods

Fifteen patients (30 eyes) bilaterally implanted with the Asqelio Pluris IOL were evaluated at 3 months. Monocular and binocular visual acuity at distance, intermediate, and near were measured in logMAR units. Binocular photopic defocus curves were obtained from +2.00 to −4.00 D in 0.50 D steps. Patient-reported outcomes were collected.

Results

The mean age of patients was 77.0±9.3 years (range 64-85 years) with a preoperative spherical equivalent of 0.93±2.24D (+3.25 to -2.5D). At 3 months, mean residual spherical equivalent was -0.26±0.42D (0.00 to -1.00D), mean monocular corrected distance visual acuity was 0.06±0.06 logMAR. The mean binocular defocus curve showed a peak at plano, maintaining visual acuity ≤0.20 logMAR across approximately 1.50D of defocus. No clinically relevant optical degradation or significant photic disturbances were reported.

Conclusions

Asqelio Pluris demonstrated good distance vision with extended functional range consistent with an Enhanced Partial-DOFi design. Intermediate performance was improved without compromising optical quality or increasing visual disturbances.
