title: Hinge keratoplasty.
abstract: A simple trephination technique is described that allows the surgeon to be prepared to handle an expulsive hemorrhage before it occurs. After trephination is performed, the host button is excised except for a 1 clock hour width of tissue. This hinge allows the attached button to fold over the corneal rim away from the surgical field. There is no interference with subsequent intraocular procedures. Should expulsive hemorrhage develop, the attached button can be immediately flipped into place and the wound quickly sewn closed.
