A group of visiting doctors have assembled for lunch. They’ve come from different places—Birmingham to Dubai—to conduct the Fellowship of the Royal Colleges of Surgeons exam at LV Prasad Eye Institute (LVPEI), which it has been hosting for close to two decades in Hyderabad. After some perfunctory exchanges, the conversation rests on the bow tie. How could it not? The founder of LVPEI, Dr GN Rao, fell for it, discarding the regular silk tie after a glib salesman in New York many years ago sold him the glamour of bowknots.
