title: Spontaneous Descemet membrane tear after uneventful big-bubble Deep Anterior Lamellar Keratoplasty.
abstract: OBJECTIVE
  To report a case of delayed spontaneous Descemet membrane (DM) tear after big-bubble Deep Anterior Lamellar Keratoplasty (DALK).
  
  
  METHODS
  Uneventful big-bubble DALK was performed on a 29-year-old patient with advanced keratoconus. No injury to DM was noted intraoperatively and in the first postoperative week. On examination after 1 month, the patient presented with tear and partial detachment of Descemet membrane (DMD).
  
  
  RESULTS
  Circumscribed eccentric stromal edema, but not DMD, partially resolved after a 3-month observational period.
  
  
  CONCLUSIONS
  A tear to DM and consecutive DMD may occur spontaneously after big-bubble DALK. Sutural traction and regressing corneal stromal edema may be etiologic factors.
