[New trends in corneal surgery. Grafting stem cells and performing lameliar graft].
Epithelial, stromal or endothelial diseases can generate corneal opacity. A lake of corneal epithelial cells leads to corneal opacity and low visual acuity. In these cases, corneal epithelial stem cells from the limbus of the healthy eye or from relatives or other people must be grafted to regenerate corneal epithelium. It is also possible to cultivate corneal stem cells harvested from the sick eye, the healthy eye (autologous culture) or from relatives (allotypic culture). Renewing epithelial cells is not always sufficient to restore corneal transparency. It can also be necessary to replace a part or the entire corneal stroma. We can use today surgical lamellar graft technics to replace only stromal corneal layers involved in the disease we cure.
