Retention of the host's Descemet's membrane is a complication which can occur during the course of a penetrating keratoplasty and which eventually leads to loss of graft clarity by clouding or by coming into contact with the graft endothelium. The retained Descemet's membrane can compromise endothelial tissue by contact injury or by limiting diffusion of aqueous humour nutrients.

In our study we discuss the pathogenesis, diagnosis and treatment of this complication. In addition we report some our cases treated with three different approaches.
