Recession Coverage Using Soft Tissue Substitutes
2018
Today, a variety of surgical procedures can be used to successfully treat gingival recession defects. Among them, the autogenous connective tissue graft in conjunction with a coronally advanced flap is commonly considered the gold standard procedure. However, the most significant disadvantages of this procedure are the potential morbidity associated with autogenous tissue harvesting and the limited availability of donor tissue. For these reasons, alternative surgical procedures using membranes, enamel matrix derivative, and soft tissue graft substitutes have been proposed and tested. The aim of the present chapter is to provide an overview on the use of soft tissue substitutes as a possible…
Irregularity of the posterior corneal surface after curved interface femtosecond laser-assisted versus microkeratome-assisted descemet stripping auto…

During donor tissue preparation for Descemet stripping automated endothelial keratoplasty (DSAEK), either microkeratome or femtosecond laser can be used for intrastromal cutting. We compared morphological and functional outcomes after DSAEK using both cutting techniques.In this retrospective study, 22 uneventful DSAEK surgeries were reviewed. Eight donor corneas were prepared for DSAEK using the VisuMax femtosecond laser (Carl Zeiss Meditec AG, Jena, Germany). Fourteen corneas were processed using an Amadeus II microkeratome (Ziemer Ophthalmic Systems AG, Port, Switzerland). The postoperative best spectacle-corrected visual acuity was measured. Furthermore, corneal optical coherence tomogra…
