  • ABSTRACT: Definitive treatment for loss of corneal transparency or for corneal distortion is a corneal transplant. When the sight affecting pathology lies in the corneal stroma, deep anterior lamellar keratoplasty (DALK) allows retention of the healthy recipient endothelium and Descemet’s layer. The “Big Bubble” (BB) technique described by Mohamed Anwar is the most popular Descemet’s baring technique worldwide. It involves the injection of air into the corneal stroma, thus stripping the DM from the deep stroma and allowing excision of the affected tissue. Over nearly a decade of performing DALK by the BB technique, a number of clues pointed to a novelty in the surgical anatomy of the posterior cornea which, after characterisation, was termed the Dua’s layer.

    This report summarizes the events that suggested the existence, provided evidence, and finally led to the characterisation of the Dua’s layer, along to its clinical relevance and the applications of this discovery
