Femtosecond laser versus mechanical microkeratomes for flap creation in laser in situ keratomileusis and effect of postoperative measurement interval on estimated femtosecond flap thickness

Abstract

Results indicate that the time of measurement after femtosecond affects the estimated flap thickness. Waiting 20 minutes after laser treatment permitted easier separation and may eliminate the effect of variable corneal dehydration on flap measurement by subtraction pachymetry.

Corneal flap assessment with Rondo microkeratome in laser in situ keratomileusis

“…However, Rondo exhibited comparable results with other microkeratomes [14,26,[30][31][32][33][34][35][36][37][38][39][40][41][42][43]; a complete comparison is presented in Table 2.…”

Simultaneous corneal inlay implantation and laser in situ keratomileusis for presbyopia in patients with hyperopia, myopia, or emmetropia: Six-month results

“…Although initially widely debated, femtosecond lasers have been reported to provide better predictability in flap surface dimensions, precise target depth, a lower incidence of LASIK-induced dry eye, improved contrast sensitivity, greater patient satisfaction, quicker visual recovery, and better UDVA results relative to microkeratomes. [30][31][32][33][34][35][36] In conclusion, LASIK provides patients with highly predictable, safe, and effective outcomes for the treatment of refractive errors. Small-aperture inlays are reported to be useful for the treatment of presbyopia.…”

Corneal deformation signal waveform analysis in keratoconic versus post-femtosecond laser in situ keratomileusis eyes after statistical correction for potentially confounding factors

“…In this study, we excluded from our study eyes that had LASIK using a microkeratome to reduce the confounding effect of flapinduced biomechanical variability. 18,19 We evaluated whether the Ocular Response Analyzer device provides information to distinguish biomechanical differences between a pathologic disease (keratoconus) and an iatrogenically altered normal cornea (post-femtosecond flap LASIK).…”
