Keratoconus (KC) is a bilateral sight threatening disease that affects the cornea. It consists of a gradual steepening of the central cornea associated with irregular astigmatism and may lead to corneal opacities. In some cases, a keratoplasty is needed to restore vision. Even though it is not frequent, recurrence of KC in donor tissue has been described, and is usually bilateral. Recurrence may respond to problems related to the corneal graft or to personal and environmental factors that persist after surgery. We present a case of a recurrent KC 20 years after a keratoplasty with clinical, topographic, and histopathological analysis.
