Discovery of Dua's layer
In a 2013 paper, Dua and others at the University of Nottingham reported discovery of a previously unknown layer of the human cornea measuring just 15 micrometres thick between the corneal stroma and Descemet's membrane. They refer to the reported layer as Dua's layer. However, this was considered very controversial in the field due to the convention within the medical community to stop using eponyms. In 2001,he proposed Dua classification for chemical injuries in eye.
