The Ocular Surface Institute, or TOSI (pronounced as “To See”), is the leading ocular surface institute in the United States, with the goal of broadening translational research in ocular surface health. Over the years, the University of Houston, College of Optometry (UHCO) has shown a dedicated commitment to the pursuit of research across multiple aspects of vision science. In 2012, the opening of the Vision Institute located at the University of Houston Health & Biomedical Sciences Building, has provided the opportunity to advance ocular research with state of the art technology in a modern setting that is designed to facilitate collaborations across multiple disciplines. It is TOSI’s goal to develop the world’s broadest and most visionary research institute devoted to ocular surface translational research.

Assistant Professor, UHCOdberntsen@optometry.uh.edu Dr. David Berntsen’s research interests include juvenile–onset myopia, contact lenses, and both central and peripheral aberrations of the eye. He completed a Cornea and Contact Lens Advanced Practice Fellowship in 2004 at The Ohio State University where he examined the effects of overnight orthokeratology on higher–order aberrations, visual acuity, and refractive error–specific quality of life. He completed a PhD in Vision Science in 2009 at The Ohio State University where he conducted a randomized clinical trial evaluating current theories of myopia progression in children. His PhD training included a strong background in epidemiology and clinical trials methodology. Dr. Berntsen has been involved in multiple other adult and pediatric studies in the areas of contact lenses, dry eye, and higher-order aberrations of the eye.

Professor, UHCOaburns@optometry.uh.edu Dr. Alan Burns is a Professor with 40 years experience in cell biology and microscopic imaging. During the past seven years, his research program has centered on the cornea. The location of the cornea makes it vulnerable to traumatic injury, either accidental or as a result of surgery. Healing of corneal wounds is of vital importance, not only to ensure the integrity of the eye but also to maintain the best possible visual acuity. The mechanisms regulating healing after corneal injury are not fully understood. Migration of inflammatory cells to the site of corneal injury appears to be beneficial for wound healing. Inhibition of inflammatory cell migration results in impaired wound healing, and decreased growth of specific cells in the cornea (keratocytes, nerves and epithelial cells). His experiments are designed to understand the mechanisms regulating inflammation and wound healing within the injured cornea.
