Cochrane is the only international organization that has the goal of synthesizing and keeping up to date the evidence for all of healthcare. Systematic reviews use explicit methods to identify, appraise, and synthesize available evidence for a clinical question. Cochrane Eyes and Vision (CEV) aims to prepare and promote access to systematic reviews of interventions used to prevent or treat eye conditions and/or visual impairment, and to help people adjust to visual impairment or blindness. For 17 years, CEV United States Satellite (CEV@US) has overseen production of systematic reviews contributing to eyes and vision comparative effectiveness research in the US in many ways. The purpose of comparative effectiveness research is to assist patients, clinicians, purchasers, and policy makers in making informed health decisions, and to contribute to evidence-based healthcare. Specifically, CEV@US aims to 

  1. Build a comparative effectiveness research workforce within the field of vision science by educating and training health professionals on key topics; 
  2. Partner with professional societies, academic medical centers, journals, and others to ensure that the knowledge underpinning clinical practice is reliable, available, and applied; 
  3. Prepare systematic reviews addressing prioritized questions, publish the reviews, and regularly update them as new research emerges; 
  4. Conduct foundational methodological research related to systematic reviews; 
  5. Disseminate the results of our research.
