Vergleich der Langzeitergebnisse bei Small Incision Refractive Lenticule Extraction (ReLEx SMILE) und Femto-LASIK

Zusammenfassung

Zielsetzung Ziel dieser retrospektiven Analyse war es, im 5-Jahres-Verlauf die ReLEx-SMILE-Methode und die femtosekundenlaserassistierte LASIK (FsLASIK, Femto-LASIK) in Bezug auf Sicherheit, Effektivität, Stabilität und intraoperative Komplikationen umfassend zu vergleichen. Bisherige Vergleichsstudien beschränken sich auf maximal 3 Jahre, sodass unsere Ergebnisse erstmalig längerfristige Daten zeigen.

Material/Methoden Es wurden 404 Augen nach FsLASIK (Mel 80, Carl Zeiss Meditec) und 1192 Augen nach ReLEx SMILE (VisuMax, Carl Zeiss Meditec) verglichen. Erhoben wurden die verwendeten Patientendaten 6 Monate, 1 Jahr, 2 Jahre, 3 Jahre und 5 Jahre nach refraktivem Eingriff.

Ergebnisse Fünf Jahre postoperativ zeigten beide Methoden vergleichbare Ergebnisse bei allen untersuchten Parametern. Innerhalb dieser 5 Jahre zeigte die ReLEx-SMILE-Methode hinsichtlich Sicherheit nach 6 Monaten, 1 Jahr und 2 Jahren signifikant bessere Visuswerte (p < 0,05). Auch der Verlauf des Fernvisus war nach der ReLEx-SMILE-Methode 1 Jahr, 2 Jahre und 3 Jahre postoperativ signifikant besser. Die Vorhersagbarkeit beider Methoden war gleichwertig und auch die intraoperativen Komplikationen fielen bei beiden Methoden gleich niedrig aus.

Zusammenfassung Die retrospektive Analyse unserer 5-Jahres-Ergebnisse zeigt, dass die ReLEx-SMILE-Methode und die FsLASIK mindestens ebenbürtig in Bezug auf die Sicherheit und Effektivität sowie Stabilität der Refraktionswerte sind. Aufgrund der hohen Patientenzufriedenheit, des hohen postoperativen Patientenkomforts und der naturgemäßen Abwesenheit von Flap-Komplikationen ist die ReLEx SMILE bei uns und unseren Patienten die Methode der Wahl, wenn es um einen refraktivchirurgischen Eingriff an der Hornhaut zur Korrektur von Myopie und myopem Astigmatismus geht.

Abstract

Aim Our aim was to retrospectively compare ReLEx Smile to femtosecondlaser-assisted LASIK (FsLASIK, femto-LASIK) in terms of safety, efficacy, stability as well as intraoperative complications. Comparable studies only show the results over the course of 3 years, making our data the first to examine longer term results.

Materials/Methods To accomplish this, we compared 404 eyes after FsLASIK (Mel 80, Carl Zeiss Meditec) and 1192 eyes after ReLEx SMILE (VisuMax, Carl Zeiss Meditec). We collected patientsʼ data at 6 months, 1 year, 2 years and 5 years after refractive surgery.

Results Five years postoperatively, the 2 methods showed equally good results in all investigated parameters. Over the course of these 5 years, the ReLEx SMILE achieved significantly better results for safety (p < 0.05) after 6 months, 1 year and 2 years. The results for visual acuity were significantly better for ReLEx SMILE after 1, 2 and 3 years. The predictability of both methods was consistently good over the entire period of time and intraoperative complications were equally low.

Conclusion After retrospective analysis of the visual outcomes of our patients up to 5 years after surgery, the ReLEx SMILE method turned out to be at least as safe and efficient as the FsLASIK. The stability of the refractive outcome was equally good with the 2 methods. Due to the high level of satisfaction experienced by the patients, high patient comfort intra- and postoperatively, absence of dry eyes, and the absence of flap complications, ReLEx SMILE has replaced the FsLASIK in our daily practice and become our method of choice for corneal refractive surgery when it comes to the correction of myopia and myopic astigmatism.
