Conjunctivodacryocystorhinostomy (CDCR) surgery provides relief to thousands of people every year who suffer from tear duct problems ranging from collapsed tear ducts and excessive tearing caused by accident, injury, birth defects, or environmental strain.  Left untreated, patients may experience swelling, infections, increased swelling, tearing "wet eye” and severe pain.

In 1963, Dr. Lester T. Jones and Gunther Weiss collaborated in developing a solution for tear duct problems. They developed highly specialized glass tubes called "Lester T. Jones Tear Duct Tubes", designed for insertion into the nasolacrimal duct. The body develops scar tissue around the tube, which holds it in place, forming a new tear duct.

In 2012 GWSG entered the new realm of Eye Banking. Scott Wheeler in collaboration with various EBAA eye banks created glass cannulas for tissue transportation and placement. The various shapes and sizes of the cannulas provide various different benefits for cornea surgeons and patients all around the world.

Jones Tear Duct Tubes in a variety of lengths and diameters to address most patient needs.  We are also always open to collaboration on new devices; if you ‘see’ an opportunity for us to connect please don’t hesitate to reach out to us!
