Purpose To describe a novel technique in unfolding an endothelium-in Descemet membrane (DM) graft. Methods New surgical technique description Results We describe a novel technique that allows immediate and controlled unfolding of the endothelium-in Descemet membrane graft that was successful in 5 of our DMEK patients. It is essential to acquire this “side press-and-release” technique when the graft does not unfold spontaneously as expected. Conclusions This controlled and simple manoeuvre is an efficient and safe method of unfolding an endothelium-in DM graft.

History Of

A 65-year-old patient with history of keratoconus, mild cataract and penetrating keratoplasty over 30 years ago developed corneal oedema subsequent of graft failure with best corrected visual acuity (BCVA) of counting fingers. He underwent a successful cataract surgery combined with a 7.25 mm Descemet’s Membrane Endothelial Keratoplasty (DMEK) with Sodium Hexafluoride (SF6) gas. His cornea remained oedematous inferiorly at 4 weeks, despite two subsequent re-bubbling due to persistent DMEK detachment inferiorly. This was managed by three radial full thickness 10-0 nylon sutures placed in the inferior cornea along with intracameral injection of air. Following this, his anterior segment ocular coherence tomography (OCT) confirmed complete attachment of the graft, and the sutures were removed 4 weeks later. Unaided visual acuity was 20/63 and BCVA was 20/32 after 8 months. DMEK suturing can be helpful in persistent DMEK detachments, which is refractory to repeated re-bubbling due to uneven posterior surface of previous PK.
