Intraocular lenses (IOLs) provide long-term stability and effective vision correction across multiple distances, making them reliable options for presbyopia correction even several years after implantation, according to a study.
A recent study assessed the long-term visual outcomes and alignment stability of 2 toric IOLs—the AT Lisa Tri Toric and the Acrysof IQ Restor Toric , more than 3 years post-implantation. The research included 42 eyes with follow-up periods averaging 5.4 years for the AT Lisa group and 7.9 years for the Acrysof IQ Restor group.
Both IOLs demonstrated excellent long-term axial stability. The AT Lisa group showed a mean misalignment of 4.8° ± 3.2°, while the Acrysof IQ Restor group had 5.4° ± 4.5°—a difference that was not statistically significant. Postoperative spherical equivalent refractions were well-aligned, with most eyes achieving a target range between -0.50 and +0.50 diopters.
Visual outcomes were also favorable. In the AT Lisa group, 72% of eyes achieved uncorrected distance visual acuity of 20/25 or better, compared to 88% in the Acrysof IQ Restor group. Both IOLs provided effective vision correction at far, intermediate, and near distances.
The findings confirm that the AT Lisa Tri Toric and Acrysof IQ Restor Toric IOLs are stable and effective for long-term use.
