introduction: to compare the efficacy and cost-effectiveness of femtosecond laser versus mechanical microkeratome corneal flap creation in correction of refractive errors. methods: i this review, a comprehensive search of medline, scopus, cochrane, trip database, supplemented by hta and economic databases was performed. we searched for randomized controlled trials (rcts) of femtosecond laser wh...

introduction: when aesthetics is compromised, dental ceramics are excellent materials for dental restorations; owing to their optical properties and biocompatibility, zirconia ceramics are particularly interesting. self-adhesive resin cements are the most suitable for bonding to zirconia ceramics, but traditional adhesive chemistry is ineffective and surface treatments are required to improve t...

introduction: the aim of this study was to evaluate the morphological changes and quantitatively assess the roughness of dentin after the ablation with a ytterbium-doped potassium yttrium tungstate (yb: kyw) thin-disk femtosecond pulsed laser of different fluences, scanning speeds and scanning distances. method: twelve extracted human premolars were sectioned into crowns and roots along the cem...

PURPOSE To describe stromal changes after a femtosecond laser laser-assisted in situ keratomileusis (LASIK) flap was created but not separated. DESIGN Case report. METHODS As part of a randomized paired-eye study comparing LASIK flap creation by a femtosecond laser to a mechanical microkeratome, a femtosecond laser flap was successfully created on one eye of one patient, but the flap was no...

A long air plasma channel can be formed by filamentation of intense femtosecond laser pulses. However, the lifetime of the plasma channel produced by a single femtosecond laser pulse is too short (only a few nanoseconds) for many potential applications based on the conductivity of the plasma channel. Therefore, prolonging the lifetime of the plasma channel is one of the key challenges in the re...

PURPOSE To compare functional and morphological outcomes of femtosecond laser clear corneal incision (CCI) versus manual CCI during cataract surgery. METHODS Sixty eyes of 60 patients who underwent CCI during cataract surgery were randomized into two groups: femtosecond laser CCI (30 eyes) and manual CCI (30 eyes). RESULTS There were no significant between-group differences in uncorrected d...

PURPOSE To evaluate the thickness and side-cut angle of laser in situ keratomileusis (LASIK) flaps created by 1 of 3 femtosecond lasers or a microkeratome using Fourier-domain optical coherence tomography (OCT). SETTING Department of Ophthalmology, Institute of Vision Research, Yonsei University College of Medicine, Seoul, Korea. DESIGN Comparative case series. METHODS Flap creation for b...

Femtosecond laser-assisted cataract surgery has grown in popularity among ophthalmologists as a novel technique with the potential to reduce phacoemulsification energy requirements.1,2 However, early adoption of femtosecond laser-assisted cataract surgery by experienced cataract surgeons has been associated with a significant learning curve.3 Roberts et al. reported higher complication rates in...

PURPOSE To assess and compare the morphology of laser in situ keratomileusis flaps (LASIK) created by a 60 kHz femtosecond laser and a mechanical microkeratome. SETTING Department of Ophthalmology, Johann Wolfgang Goethe-University, Frankfurt am Main, Germany. METHODS Anterior segment optical coherence tomography (AS-OCT) (Visante) was used to assess 1 week postoperatively the morphology of...
