Corneal perforation and decompensation after automated lamellar keratoplasty for hyperopia

We describe a case of corneal perforation and decompensation after automated lamellar keratoplasty (ALK) in a middle-aged hyperopic man who had had unsuccessful holmium laser thermokeratoplasty. The corneal decompensation responded to gluing and application of a bandage contact lens but despite treatment, the corneal flap remained precariously poised with a localized area of thinning that is predisposed to future perforation and decompensation. This case highlights the potential for serious complications and subsequent visual morbidity after ALK.
