ABSTRACT

Introduction: Penetrating keratoplasty is a procedure for optic and therapeutic purpose. Corneal clarity following penetrating keratoplasty depends on the maintenance of healthy endothelial cells. The loss of endothelial cells following surgery has been demonstrated and depends on various factors.
Objective: To measure endothelial cell count and pachymetry in corneal transplanted patients and determine risk factors to prevent endothelial cells loss.
Methods: Specular microscopy was realized on the 15th and 30th day after surgery in patients with corneal transplant. Cell count and corneal thickness was determined.
Results: We found an endothelial cell loss of 15.93% after surgery. No relation between endothelial cell loss and diagnosis or age of the receptor could be determined.
On the other hand a relation between endothelial cell loss and time of enucleation and graft setting was found.
Conclusions: Penetrating keratoplasty must be done as soon as possible. Unfortunately it is difficult to obtain the graft. We must be aware of the risk factors which predispose to corneal rejection in order to prevent it.
