The objective is to measure the range of vision and patient reported visual disturbances after bilateral implantation for this unique non-diffractive extended depth of focus (EDOF) intraocular lens (IOL) made from the Clareon material.
This study is a single-arm unmasked clinical evaluation study of binocular distance-corrected distance (6m) and intermediate (66cm) visual acuity after successful bilateral cataract surgery. Subjects will be assessed pre-operatively, operatively and at 1 day, 1 month and 3 months post-operatively. Clinical evaluations will include administration of a visual disturbance questionnaire (QUVID), and a satisfaction questionnaire (IOLSAT), as well as measurement of bilateral visual acuity and manifest refraction.
