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 * Predefined postoperative residual astigmatism to be \< 0.5 D (calculated with Barrett total K toric calculator) * Calculated IOL power within the range of the investigated IOL * Pupil size ≥ 5 mm (in mydriasis) * Willingness to comply with the postoperative follow-up examination schedule * Written informed consent prior to surgery Exclusion Criteria: * Previous ocular surgery or trauma * Extreme shallow anterior chamber * Uncontrolled systemic or ocular disease * Associated corneal pathologies (e.g., edema, scarring) or relevant other ophthalmic diseases that may result in altered visual outcome or lens stability (e.g., pseudoexfoliation syndrome, floppy iris syndrome, glaucoma, retinal disease) * Concurrent participation in another clinical investigation * Pregnancy or lactation (pregnancy test will be performed in women of reproductive age)
