Created in 2009 by Leo T. Chylack, Jr., M.D. via an exclusive license with the Brigham and Women’s Hospital in Boston, Massachusetts, Chylack Inc. seeks to promote understanding of, and training in, the Lens Opacities Classification Systems II and III (LOCS II and LOCS III) for grading the class and severity of human cataract.
