Comparative micromorphologic in vitro porcine study of IntraLase and Femto LDV femtosecond lasers

Abstract

The laser cuts of the IntraLase FS and Femto LDV femtosecond lasers were equally smooth and of excellent quality. The standard deviation of the flap thickness was small and equal in both systems.

Surface quality of human corneal lenticules after femtosecond laser surgery for myopia comparing different laser parameters

“…The advantage was evident in improved surface quality of the stromal bed in lamellar keratotomies [4,5]. A study conducted with a new 200-kHz laser (WaveLight UltraFlap -Femtosecond laser) applying 500-nJ pulse energy and 5-μm spot distance showed very smooth intrastromal cuts as judged by scanning electron microscopy.…”

“…For Femto-LASIK, refinement of laser technology was associated with smoother stromal beds [4]. This was demonstrated for flap surfaces in human donor eyes [4] and on porcine tissue for flaps [5] as well as refractive lenticules (own unpublished data). The aim of this study was to investigate the influence of laser settings on surface quality of human corneal lenticules which were extracted during the FLEx procedure using the 200 kHz VisuMax® femtosecond laser system (Carl Zeiss Meditec AG, Jena, Germany).…”

Effect of varying microkeratome parameters on laser in situ keratomileusis interface surfaces

“…Recent studies 8,10,11 show that femtosecond lasers may produce smoother surfaces than some mechanical microkeratomes; however, it is not known whether this results in better functional outcomes.…”

Comparison of femtosecond and excimer laser platforms available for corneal refractive surgery

“…Other studies, however, have not demonstrated such difference in flap morphology between laser platforms. Kermani and Oberheide [17] found that laser cuts made with the Intralase FS 60-kHz and Femto LDV laser systems were equally smooth and of excellent quality. A more recent prospective study by Zhang et al [18] showed that while LASIK flaps made with the Femto LDV were thinner, flap predictability and uniformity otherwise did not differ between the Intralase FS 60-kHz and Femto LDV systems.…”
