LFR-260 vs Traditional Phoropter in Visual Acuity Testing

Completed · Not applicable

Conditions studied: Visual Acuity, Astigmatism, Anisometropia

In brief

The purpose of this study is to establish if LFR-260 (investigational device) is not inferior in effectiveness to a traditional phoropter (control device) when applied in visual acuity test in subjects undergoing a full routine eye examination. LFR-260 proposes to provide information of the visual capabilities of the patient. The test will be provided and supervised by a qualified eye care provider.
