Spontaneous corneal perforation following acute hydrops in a patient with keratoconus is an exceptionally rare event. Two cases have been reported in the literature; one patient with fistula formation after 2 years of persistent hydrops,1 and a young, pregnant woman whose cornea perforated after a course of topical corticosteroids.2 We report two cases of spontaneous corneal perforation after acute hydrops in keratoconus.
