To report successful management of a case of persistent keratoconus-related hydrops with a Descemet membrane endothelial keratoplasty (DMEK) patch graft.


A case of corneal hydrops persisting for 7 months treated with DMEK was identified. The following information was collected: demographic data, surgical indications, clinical course, diagnostic tests, and clinical outcome.


A 55-year-old patient with an established diagnosis of keratoconus was followed for 7 months without improvement in his acute corneal hydrops. Because of excellent vision and central corneal clarity, the patient was treated with a 5-mm DMEK covering the Descemet membrane tear, developing cataract secondary to the procedure, but with resolution of his corneal hydrops. An uncorrected visual acuity of 20/25 was achieved after uncomplicated cataract extraction.


DMEK, although technically challenging, can be considered for patients with persistent hydrops with preservation of corneal clarity and contour in areas of the uninvolved cornea.
