Visual outcomes and rotational stability of a new non-diffractive extended-vision toric intraocular lens.

OBJECTIVE

To evaluate visual outcomes and intraocular lens (IOL) rotational stability of patients undergoing immediate sequential bilateral cataract surgery with a non-diffractive extended-depth-of-focus toric IOL.

DESIGN

Non-comparative single-centre cohort study.

PARTICIPANTS

Twenty patients (40 eyes) with significant cataracts and corneal astigmatism who underwent immediate sequential bilateral cataract surgery with the AcrySof IQ Vivity Extended Vision Lens (Alcon Laboratories Inc, Fort Worth, Tex.).

METHODS

Binocular uncorrected visual acuities (UCVA) and monocular best-corrected visual acuities (BCVA) were assessed at distance (6 m), intermediate (66 cm), and near (40 cm) postoperatively at 1 week and 3 months. The rotational stability of each IOL was assessed at 1 day, 1 week, and 3 months postoperatively. A validated questionnaire (Questionnaire for Visual Disturbances [QUVID]) was used for patient-reported subjective visual disturbances preoperatively at a 3-month follow-up.

RESULTS

Binocular distance, intermediate, and near UCVAs (mean ± SD) were 0.00 ± 0.16, 0.09 ± 0.08, and 0.14 ± 0.11 logMAR at 1 week and 0.01 ± 0.06, 0.08 ± 0.08, and 0.14 ± 0.07 logMAR at 3 months postoperatively, respectively. Distance monocular BCVA improved from 0.22 ± 0.23 logMAR preoperatively to 0.02 ± 0.06 logMAR at 3 months. Monocular BCVAs at 3 months were 0.08 ± 0.08 logMAR at intermediate distance and 0.05 ± 0.08 logMAR at near distance. IOL rotation from the intended placement axis was 2.5 ± 1.7 degrees at 1 week and 1.7 ± 1.7 degrees at 3 months postoperatively.

CONCLUSIONS

The AcrySof IQ Vivity Extended Vision IOL achieved good UCVAs and BCVAs for distance, intermediate, and near vision. This IOL also provided excellent rotational stability for astigmatism correction.
