Chylack Incorporated

Established 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 the Lens Opacities Classification System III (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 III for ongoing and/or potential research projects.

   As you consider next steps with your team, please note that the LOCS Standards are protected under copyright and may not be copied, scanned, or reproduced in any way, via any technology. The LOCS III standard may not be posted on a network or stored in any digital capacity. It also may not be resold for profit. It is important to make this clear to all study team members in advance of a study's initiation.

    Please contact us if you would like to discuss how LOCS can address your research goals. We look forward to working with you.
