In 1982, Dr. Tennant was invited to lecture at an international meeting of cataract surgeons at GlenEagles, Scotland.


A few years later, Dr. Tennant was one of about ten surgeons from Europe, Russia, and the US to perform cataract surgery live in London before an international audience of surgeons.  All of the surgeons except Dr. Tennant used general anesthesia.  


Dr. Tennant with the assistance of his anesthesiologist, Monte Hellman and his nurse, Shirley Eason, operated using local anesthesia and the Tennant Standard Lens.  The patient walked away from the surgery and began assisting the other patients in the recovery room that were vomiting from their anesthesia experience!
