This is a study to assess the spectacle independence and quality of vision of patients receiving the AcrySof® Panoptix® Intraocular lens (IOL) after uneventful cataract surgery.
This study is a single-arm unmasked clinical evaluation study of spectacle independence 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 spectacle independence questionnaire, as well as measurement of bilateral visual acuity and manifest refraction.

Number of Emmetropic Subjects Who Are Spectacle Independent
Number of patients who have a 3-month postoperative manifest spherical equivalent refraction within 0.5 diopters (D) of plano, and ≤ 0.5 D of refractive cylinder (emmetropic subgroup) who never or rarely wear spectacles for distance, intermediate or near vision 3 months postop (based on the Patient-Reported Spectacle Independence Questionnaire (PRSIQ) - "a little of the time" or "none of the time").
