'''Dua's layer''' is a thin, previously unrecognized, part of the [[cornea]] in the human [[eye]]. It was discovered in 2013 by Harminder Dua, a professor of [[ophthalmology]] at the University of Nottingham, and his team. The layer is located at the back of the cornea between the [[corneal stroma]] and [[Descemet's membrane]].

==Etymology==
The layer is named after its discoverer, Harminder Dua. The term "Dua's layer" was first used in a paper published in the journal [[Ophthalmology (journal)|Ophthalmology]] in June 2013.

==Structure==
Dua's layer is only about 15 micrometres thick, but it is incredibly tough and strong. It is made up of thin plates of [[collagen]] and is impervious to air. The layer is located at the back of the cornea, just in front of Descemet's membrane.

==Function==
The function of Dua's layer is not yet fully understood. However, it is believed to play a vital role in the structure of the cornea and may contribute to the cornea's resistance to damage and disease. It may also play a role in corneal [[hydrops]], a condition in which fluid accumulates in the cornea, causing it to suddenly become opaque and vision to be lost.

==Clinical significance==
The discovery of Dua's layer has significant implications for corneal surgery, including [[corneal transplant]], [[keratoplasty]], and [[refractive surgery]]. Understanding the presence and properties of this layer could lead to safer and more effective surgical procedures. It may also have implications for the treatment of corneal diseases and conditions.
