Abstract.The observational case describes bilateral recurrent keratoconus in corneal transplants performed in a patient with self-induced keratoconus secondary to compulsive eye rubbing. Slitlamp findings demonstrated corneal stromal thinning and scarring in the patient’s right eye and temporal corneal hydrops in his left eye. Videokeratography of the right eye confirmed the presence of corneal steepening and irregular astigmatism, consistent with the diagnosis of keratoconus involving each transplant. Together with the history of ongoing compulsive eye rubbing, these findings support the concept that chronic mechanical trauma to the cornea may contribute to the development of keratoconus.
