Perspektiven der Femtosekundenlaser-assistierten Keratoplastik

The femtosecond laser technique allows completely new trephination procedures in penetrating and lamellar keratoplasty. With femtosecond laser-assisted penetrating keratoplasty it is possible to perform profiled trephination, such as top hat and mushroom profiles. Thus, it is easier to get a watertight wound closure intraoperatively and due to the larger wound surface wound healing is faster and allows early complete suture removal. In lamellar keratoplasty the femtosecond laser enables the surgeon to cut to any depth in the corneas resulting in thin corneal donor buttons, e.g. for DSAEK. In this manuscript an overview is given of the state of the art and of the perspectives of femtosecond laser keratoplasty.
