DENVER — Across four IOLs, a refractive extended depth of focus lens demonstrated the strongest natural distance image quality, followed by a full visual range IOL, according to a study.
Modulation transfer function (MTF) measurements and more complex metrics based on MTF, including the area under the MTF (MTFa), are commonly used to evaluate distance image quality for IOLs. However, visual acuity outcomes obtained in a clinical setting may not always be an indicator of quality of vision in more natural conditions, Aixa Alarcon, PhD, of Johnson & Johnson Vision, told Healio at the
