Emergency penetrating keratoplasty in corneal perforations.

Corneal perforations represent an ophthalmological emergency due to their devastating consequences. Emergency treatment is mandatory to try to restore the anatomical integrity of the globe, to salvage useful vision as much as possible and to reduce the possible complications to a minimum. The underlying conditions or disorders responsible for corneal ulcerations, and subsequently for corneal perforations are numerous, and can be either isolated or superimposed. Emergency penetrating keratoplasty is a difficult surgical procedure that is associated with various complications, which can jeopardize the outcome of the eye.
