Über die Zukunft der refraktiven Hornhautchirurgie

  • G. Grabner
Conference paper

Zusammenfassung

Die verschiedenen Techniken der refraktiven Hornhautchirurgie haben im letzten Jahrzehnt eine sehr rasche Entwicklung durchgemacht. Sowohl die Methoden der Keratotomie (radiär, tangential, hexagonal), als auch die lamellierenden Verfahren (Keratophakie, Keratomileusis, Epikeratophakie) sind wesentlich verbessert worden, obwohl die derzeit erzielbaren Ergebnisse noch immer viele Probleme ungelöst lassen. Die Entwicklung neuer Laser (Excimer, Ho:YAG, HF und andere) hat zu großen Hoffnungen Anlaß gegeben, daß eine präzise, stabile und risikolose Korrektur verschiedenster Brechungsfehler in naher Zukunft erreichbar sein könnte. Auch hier sind keineswegs alle Fragen zufriedenstellend gelöst. Intrakorneale Implantate verschiedenster Konfiguration (Linse, Ring) befinden sich in den frühen Stadien klinischer Erprobung. In dieser Übersichtsarbeit wird der gegenwärtige Stand der refraktiven Hornhautchirurgie mit einem Ausblick auf die möglichen zukünftigen Entwicklungen dargestellt.

Summary

Refractive corneal surgery has rapidly developed over the last decade. Both, the incisional techniques (radial, tangential, hexagonal), as well as the lamellar refractive procedures (keratophakia, keratomileusis, epikeratophakia) have been markedly improved, although the current results still leave many problems unanswered. The recent development of new lasers (excimer, Ho:YAG, HF, and others) has prompted great expectations as to the feasibility of a precise and stable correction of a variety of refractive errors without risks involved. Up to date this hope as not been completely fulfilled. Intracorneal implants in different shapes (lens, ring) are in the early clinical stages of investigation. In this review the current status of refractive corneal surgery is analysed with an outlook at possible future developments.
