. However, this was considered very controversial in the field due to the convention within the medical community to stop using eponyms. McKee, Hamish D.; Irion, Luciane C.D.; Carley, Fiona M.; Brahma, Arun K.; Jafarinasab, Mohammad R.; Rahmati-Kamel, Mohsen; Kanavi, Mozhgan R.; Feizi, Sepehr (May 2014). "Re: Dua et al.: Human corneal anatomy redefined: a novel pre-Descemet layer (Dua's layer) (Ophthalmology 2013;120:1778–85)". Ophthalmology. 121 (5): e24–e25. doi:10.1016/j.ophtha.2013.12.021. . Abstract: We read the recent claim of the discovery of a new corneal layer by Dua et al with incredulity.1 The existence of pre-Descemet stromal tissue remaining after pneumodissection is well known. Their further investigation of this pre-Descemet stroma confirms that it is stroma, and not a new corneal layer. In 2001,he proposed Dua classification for chemical injuries in eye.
