Zusammenfassung

Als lamelläre refraktive Hornhautverfahren stehen die Laser-in-situ-Keratomileusis (LASIK) mittels Mikrokeratom oder Femtosekundenlaser-Schnitt, gefolgt von der Excimerlaserhornhautablation, sowie die rein femtosekundenlasergesteuerte refraktive Lentikelextraktion (ReLEx) zur Verfügung. Diese Operationen gelten heute als sicheres und effektives Standardverfahren der chirurgischen Korrektur von geringen bis mittleren Ametropien. Zu den Komplikationen gehören u. a. optisch wirksame Fehler, intraoperative Schnittfehler und postoperative Entzündungsreaktionen (diffuse lamelläre Keratitis, DLK), Epithel- oder Flapfalten, Epitheleinwachsungen oder die iatrogene Keratektasie. Die Einhaltung entsprechender – auf dem aktuellen wissenschaftlichen Kenntnisstand basierender – Indikations- und Behandlungsstandards kann das Auftreten dieser Komplikationen erheblich vermindern.

Abstract

Techniques available for corneal lamellar refractive surgery are laser-assisted in situ keratomileusis (LASIK) using a microkeratome or femtosecond laser incision followed by excimer laser corneal ablation, and femtosecond laser-assisted refractive lenticule extraction (ReLEx). These treatments are nowadays considered to be safe and effective standard procedures for surgical correction of mild to moderate ametropia. Possible complications include too small or decentered optical zones, intraoperative flap cutting errors and postoperative inflammation (e.g. diffuse lamellar keratitis, DLK), epithelial or flap folds, epithelial ingrowths or iatrogenic ectasia. The occurrence of complications may be significantly reduced by compliance to corresponding standards of indication and treatment that are based on current scientific knowledge.
