Update Femtosekundenlaser-Technologien in der Augenheilkunde

Zusammenfassung

Femtosekundenlaser (fs-Laser) haben sich in der refraktiven Chirurgie gegenüber dem klassischen Mikrokeratom innerhalb eines Jahrzehnts einen Marktanteil von über 55 % erobert. In der Kataraktchirurgie könnten wir vor einer ähnlichen Revolution stehen. Was macht diese Technologie so besonders und in welchen Anwendungsbereichen könnte der fs-Laser darüber hinaus Einzug halten? In dieser Übersicht werden die wichtigsten physikalisch-technischen Eigenschaften der Femtosekundenlaser beschrieben. Das Verständnis dafür soll dem Leser einerseits einen besseren Überblick über die derzeitige Marktsituation verschaffen. Darüber hinaus lässt sich darauf aufbauend abschätzen, welche kurz- und langfristige weitere Entwicklung diese Technologie einschlagen könnte.

Abstract

Femtosecond (fs) lasers for LASIK flap creation have increased their market share from 0 percent in 2001 to over 55 percent in 2010. Now, in cataract surgery a similar revolution may take place. What makes this technology so special and which new areas of surgery will furthermore be entered in the future? This review elucidates the most important technical features of the fs lasers and interaction processes with the tissue. This understanding is intended to provide a better overview of the current market situation on the one hand. In addition, it can be estimated what kind of short- and long-term development this technology could take in the future.
