Rotational Stability, Safety And Visual Outcomes Of The Asqelio™ Trifocal Toric Intraocular Lens

This prospective, observational, post-marketing study aims to evaluate the rotational stability and clinical performance of the Asqelio™ Trifocal Toric intraocular lens (IOL) in patients undergoing bilateral cataract surgery three months after implantation.

Department of Ophthalmology, Universitätsmedizin Rostock.

Twenty-two cataract patients were enrolled and received bilateral implantation of the Asqelio™ Trifocal Toric IOL. Clinical assessments were conducted preoperatively and at 1 day, 1 week, 1 month, and 3 months postoperative. Rotational stability, refractive outcomes, visual acuity at various distances, contrast sensitivities, and reading speed were evaluated. Reading performance was assessed using the Radner Reading Chart, recording the time in seconds for each 14-word sentence. Reading speed (words per minute, wpm) was calculated based on these times.

The data presented here reflect preliminary results at the 1 week visit post-surgery. Mean spherical equivalent was –0.25±0.50 D, while uncorrected and corrected distance visual acuities averaged 0.19±0.11 LogMAR and 0.09±0.01 LogMAR, respectively. Mean uncorrected intermediate and near visual acuities were 0.27±0.13 LogMAR, and corrected distance intermediate and near acuities averaged 0.29±0.12 LogMAR and 0.27±0.13 LogMAR, respectively. Mean reading speeds for acuity levels of 0.9/1.0, 0.8/0.9, and 0.7/0.8 were 137 ± 26 wpm, 129 ± 25 wpm, and 123 ± 26 wpm, respectively. Notably, no deviation from the intraoperative axis was observed in any lens, suggesting excellent short-term rotational stability.

These initial findings indicate robust rotational stability of the Asqelio™ Trifocal Toric IOL in the early postoperative period. Reading speeds are slightly lower than what might be expected in a fully adapted, stable situation, indicating that neuroadaptation and refractive stabilization is in progress at 1 week postop. At the time of abstract submission, the 3-months follow-up is ongoing. Complete final outcomes on rotational stability, reading speed and overall visual performance once the extended follow-up period is concluded will be presented
