Zusammenfassung
Ziel: Evaluation von Sicherheit, Stabilität und Effektivität bei der EpiLASIK mit einem 1000 Hz Excimer-Laser zur Myopiekorrektur. Methode: Bei 40 Augen von 23 Patienten wurde eine EpiLASIK mit einem Gebauer EpiLift Mikrokeratom und einem WaveLight Concept System 1000 Excimer-Laser durchgeführt. Präoperativ sowie ein und drei Monate postoperativ wurde eine komplette ophthalmologische Untersuchung durchgeführt (objektive und subjektive Refraktion, un- und bestkorrigierter Visus, Topografie, Spaltlampenuntersuchung und Applanationstonometrie). Ergebnisse: Das mittlere präoperative sphärische Äquivalent (SE) war –4,07 D (SD ± 1,89 D). Ein Monat postoperativ war das sphärische Äquivalent bei + 0,01 D (SD ± 0,33 D) und drei Monate nach EpiLASIK bei –0,06 D (SD ± 0,28 D). Drei Monate nach EpiLASIK waren 90 % der Patienten innerhalb ± 0,5 D und 97,5 % innerhalb ± 1,0 D der angestrebten Korrektur. Der Astigmatismus wurde von –0,77 D (SD ± 0,68 D) auf –0,24 D (SD ± 0,29 D) reduziert. 34 von 40 Augen hatten während der gesamten Nachbeobachtungszeit eine klare Hornhaut und sechs Augen zeigten einen Haze Grad 0,5. Schlussfolgerung: In dieser Pilotstudie zeigten sich keine Nebeneffekte, die auf eine 1000 Hertz Laserabtragung zurückzuführen sind. Die ersten klinischen Ergebnisse von einem 1000 Hertz Lasersystem mit EpiLASIK sind sehr vielversprechend.
Abstract
Purpose: The aim of this study was to evaluate the safety, stability and efficacy of Epi-LASIK with a 1000 hertz excimer laser system. Methods: 40 eyes of 23 patients underwent an Epi-LASIK procedure using the Gebauer EpiLift and the WaveLight Concept System 1000. Preoperatively as well as 1 month, and 3 months postoperatively, a complete ophthalmic examination, including objective and subjective refraction (UCVA, BCVA) and topography, was performed. Results: The mean preoperative spherical equivalent (SE) was –4.07 D (SD ± 1.89 D). 1 month after surgery, the spherical equivalent was + 0.01 D (SD ± 0.33 D), and 3 months after surgery –0.06 D (SD ± 0.28 D). 3 months after the Epi-LASIK procedure, 90 % of the patients were within ± 0.5 D of the intended correction, and 97.5 % were within ± 1.0 D of the intended correction. The astigmatism was reduced from –0.77 D (SD ± 0.68 D) to –0.24 D (SD ± 0.29 D) 3 months after surgery. 34 of the 40 eyes had a clear cornea 3 months after surgery, and 6 of the 40 eyes presented with haze grade 0.5. Conclusions: In our pilot series of 40 eyes, the use of the 1000 hertz excimer laser did not reveal any specific clinical side effects potentially associated with the use of a high repetition rate. These first results with Epi-LASIK and the WaveLight Concept System 1000 are very promising.
