Zusammenfassung
Durch die Einführung des Femtosekundenlasers eröffneten sich sowohl bei der perforierenden Keratoplastik als auch bei den lamellären Keratoplastiken völlig neue technische Möglichkeiten. Bei der perforierenden Keratoplastik ist es möglich, Stufenprofile wie das „Top-hat-“ oder das „Mushroom-Profil“ zu lasern. Hierdurch kann man einen stabileren intraoperativen Wundverschluss erreichen und aufgrund der größeren Wundfläche frühzeitig eine komplette Fadenentfernung durchführen. Bei den lamellären Verfahren bietet die Femtosekundenlaser-Technik die Möglichkeit, in beliebiger Tiefe der Hornhaut zu schneiden, um z. B. bei der DSAEK eine möglichst dünne Spenderlamelle zu erzielen. In diesem Beitrag wird ein Überblick über den aktuellen Stand der operativen Verfahren vermittelt, und die Perspektiven der Femtosekundenlaser-assistierten Keratoplastik werden aufgezeigt.
Abstract
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.
