Abstract

Traditionally, the cornea is considered to have five layers. From outside of these are the corneal epithelium, the Bowman’s membrane, the stroma, the Descemet’s membrane (DM) and the endothelium. However, in 2013, Prof. Harminder Dua described a new layer – the pre-Descemet’s layer (PDL) or the Dua’s layer – which lies between the Descemet’s membrane and the stroma [1]. The last three layers – the PDL, the Descemet’s membrane and the endothelium – together constitute the graft that is transplanted in a pre-Descemet’s endothelial keratoplasty (PDEK) [2]. The PDEK graft is created by injecting air into the donor corneoscleral rim [1, 2].
