Rotational Stability of the Acunex Vario Toric

Official title: Evaluation of the Rotational Stability of the Acunex Vario Toric Intraocular Lens

Run by Vienna Institute for Research in Ocular Surgery · NCT07925840 · Data updated 2026-11-12

This study tests whether the Acunex Vario toric extended-depth-of-focus intraocular lens stays stable in rotation and effectively reduces astigmatism for people undergoing cataract surgery.

Is this trial a fit for you?

Likely a good fit

Adults aged 21 and older with bilateral age-related cataracts, planned cataract surgery, and residual astigmatism less than 0.5 diopters postoperatively.

Probably not a fit

Patients with prior ocular surgery, complicated anterior chamber anatomy, or conditions likely to affect lens stability or visual outcome may not benefit.

What this trial studies

This interventional study evaluates the rotational stability and astigmatism correction provided by the Acunex Vario toric EDOF intraocular lens in adults with bilateral age-related cataracts. Eligible participants will undergo cataract surgery with implantation of the toric EDOF IOL in both eyes, with specific preoperative astigmatism criteria and lens power within the study range. Outcomes focus on lens rotation over time and visual performance across distances, aiming to reduce dependence on spectacles while minimizing photic phenomena. The trial adheres to standard postoperative follow-up to assess stability, refractive outcomes, and safety in a real-world surgical setting.

Why it matters

Potential benefit: If successful, patients could experience improved knitting of distance and intermediate vision with less reliance on glasses after cataract surgery.

How similar studies have gone: Prosthetic rotation-stability and toric EDOF lenses have shown promise in prior studies, though the specific Acunex Vario toric approach is being directly evaluated here.

Inclusion Criteria:

* Bilateral age-related cataract scheduled for cataract surgery
* Age 21 or older

Exclusion Criteria:

* Previous ocular surgery or trauma
* Extreme shallow anterior chamber
