We are a Chicago area-based medical device company providing innovative diagnostic solutions for ophthalmic care. Our Vision is to preserve vision. We work to maximize the useful vision of people with progressive eye disease through more effective screening, more accurate diagnosis, and more informative monitoring during disease management. We do this by improving access to testing through improved comfort, safety, efficacy, and clinical throughput. We also improve the tests themselves, with patented or patent-pending technologies that gather more information about the eye, and do it faster.
