Chylack Incorporated

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.  

    In both academic and commercial scenarios, Chylack Inc. can advise the individual clinician, institution, or company about the application of LOCS for ongoing and/or potential research projects.

    Please contact us if you would like to discuss how LOCS can address your research goals, or if you are interested in initiating a license for training and certification. We look forward to working with you.
