[The changes and influencing factors of corneal endothelial cell density after endothelial keratoplasty].

Endothelial keratoplasty is a surgery that selectively replaces the diseased endothelium and reserves the normal corneal epithelial and stromal layers. It is now gradually replacing penetrating keratoplasty in treating endothelial dysfunction. Although endothelial cell loss exists after endothelial keratoplasty, the number of lost cells is obviously less than that of penetrating keratoplasty. The amount and function of corneal endothelial cells are important factors for maintaining corneal transparency and indicating the survival of the graft. Thus, the changes of corneal endothelial cell density after surgery are significant in predicting the prognosis. This article elaborates on the changes of endothelial cell density after endothelial keratoplasty and related influencing factors, aiming to provide reference and basis for clinical diagnosis and treatment.
