[Therapy of acute keratoconus].

The incidence of acute keratoconus has increased in recent years. A defect of the endothelium and Descemet's membrane allows the aqueous to flow into the stroma. The therapy of choice is penetrating keratoplasty. The discussion concerning the best time for the operation is still going on. The present authors have performed penetrating keratoplasties on 9 patients at the acute stage during the last 2 years. The results show that early surgery can prevent progression of the symptoms, with corneal edema and pannus, and subsequent complications.
