The grooved spatula is used in deep lamellar keratoplasty, especially for baring (exposing) of Descemet's membrane (i.e. 'maximum depth anterior lamellar keratoplasty'). Following the creation of a central detachment of Descemet's membrane and endothelium (by means of deep air injection), the grooved spatula is inserted between the deepest corneal stroma and Descemet's membrane. The overlaying stroma can then be cut with Vannas scissors or a sharp blade, using the grooved spatula as an impenetrable protective barrier - to avoid touching the delicate Descemet's membrane with a sharp instrument (which would cause an immediate gash in this membrane). When one or more radial or semiradial stromal cuts have been made, the remaining stromal flaps can be safely excised with blunt tipped scissors.
