Purpose: To study the visual performance of a new refractive extended depth of focus (EDOF) intraocular lens (IOL)
Methods: Patients with age related cataract were implanted with either the Supraphob EDOF IOL or a monofocal IOL. The distance, intermediate and near visual acuity and contrast sensitivity were evaluated at 1 and 3 months postoperatively.
Results: Both groups had similar distance vision but the EDOF group had significantly better intermediate (0.2+0.2 logMAR vs. 0.75+0.19 logMAR, p<0.001) and near vision (median=N6 vs. N12, p<0.001) compared to the monofocal group at 3 months. The contrast sensitivity was similar in both groups. Less than 10% patients reported glare, halos and difficulty in driving at night in the EDOF group.
Conclusions: The Supraphob EDOF IOL was effective in improving the distance, intermediate and near vision in majority of patients and retained good contrast sensitivity with most patients reporting excellent satisfaction.
