Unintentional inversion of corneal buttons during penetrating keratoplasty: clinico-pathological report of two cases.
OBJECTIVE
This report describes the clinico-pathological features of unintentionally inverted corneal buttons in two patients.


METHODS
A clinico-pathological report.


RESULTS
Two patients who underwent repeat keratoplasty for failed grafts were found to have inverted corneal buttons on histopathological examination. A detailed description of the pathological features of the inverse keratoplasty and the clinical outcome after repeat keratoplasty is presented.


CONCLUSIONS
Inadvertent inverse keratoplasty should be considered as a rare cause of corneal graft failure. The serious complication of anterior chamber epithelialization seems to be unlikely and the prognosis following repeat penetrating keratoplasty appears to be very good.
