This randomized controlled trial evaluated the visual performance and patient-reported outcomes of the Acunex Vario AN6V extended depth of field (EDF) intraocular lens compared to the Acunex AN6 monofocal lens in patients undergoing bilateral cataract surgery. The EDF group showed significantly higher spectacle independence for near tasks at 2 months (37.5% vs 5.3%) and better visual acuities across various distances.
Key findings
- 37.5% of patients in the EDF group were spectacle-free for near tasks compared to 5.3% in the monofocal group.
- Uncorrected intermediate visual acuity was significantly better in the EDF group (0.09 ± 0.12 vs 0.16 ± 0.07; P = .035).
- Corrected near visual acuity was superior in the EDF group (0.24 ± 0.12 vs 0.37 ± 0.11; P = .001).
- The EDF group exhibited a larger range of defocus compared to the monofocal group.
Why it matters
The findings suggest that the EDF intraocular lens may provide enhanced visual outcomes and greater independence from spectacles for patients after cataract surgery, which can improve overall patient satisfaction and quality of life.
