The present study evaluated the clinical efficacy of a combined graft of autolysed antigen-extracted allogeneic (AAA) bone and microfibrillar collagen (Zyderm) covered with a resorbable collagen membrane in human infrabony defects. The results were compared at 1 year with debrided controls, AAA bone grafts alone, combined AAA bone-collagen grafts (without(More)
Two cases of delayed (36-month) Ancure hook fracture are reported in patients who experienced a decrease in aneurysm size and no evidence of endoleak. Both devices used redesigned hooks and are otherwise identical to those devices currently used in clinical practice. Notably, hook fractures were not visualized on all abdominal radiographic views, nor were(More)
PURPOSE This study was initiated to evaluate biomechanical changes using the Corvis ST tonometer (CST) on the cornea after laser in situ keratomileusis (LASIK). SETTING University Medical Center Hamburg-Eppendorf, Germany, and Care Vision Refractive Centers, Germany. DESIGN Retrospective cohort study. METHODS This retrospective study included 37 eyes(More)
PURPOSE To evaluate the effect of corneal cross-linking (CXL) in progressive keratoconus by applying in vivo static and dynamic Scheimpflug analyses. METHODS In this longitudinal retrospective study, corneal topography and tomography (Pentacam HD) and dynamic Scheimpflug-based biomechanical analyses (CorvisST [CST]) of 24 eyes of 24 patients with(More)
PURPOSE To analyze the influence of demographic and ocular factors on ocular residual astigmatism (ORA) in myopic laser in situ keratomileusis (LASIK). SETTING University Medical Center Hamburg-Eppendorf, Hamburg, Germany. DESIGN Retrospective cross-sectional data analysis. METHODS Eyes of consecutive myopic patients scheduled for LASIK were studied(More)
PURPOSE To evaluate the relationship between the thinnest point in corneal thickness and the refractive state, keratometry, age, sex, and the ocular side. SETTING Eye clinics in Germany and Austria and the Department of Ophthalmology, University Medical Center Hamburg-Eppendorf, Hamburg, Germany. DESIGN Cross-sectional study. METHODS Medical records(More)
BACKGROUND Canaloplasty provides a new option in non-penetrating glaucoma surgery. The aim of this study is to examine its early postsurgical safety and efficacy. PATIENTS AND METHODS This was a retrospective study of canaloplasties performed at our institution in 2009 (n=46, 13 of which were combined with cataract surgery). The mean follow-up was 6.0±3.4(More)
PURPOSE The aim of this study was to assess the tolerance dose of gastric mucosa for single-fraction computed tomography (CT)-guided, high-dose-rate (HDR) brachytherapy of liver malignancies. METHODS AND MATERIALS A total of 33 patients treated by CT-guided HDR brachytherapy of liver malignancies in segments II and/or III were included. Dose planning was(More)
PURPOSE To evaluate anterior and posterior changes in corneal topography and tomography after corneal crosslinking (CXL) in eyes with progressive keratoconus. METHODS Scheimpflug analyses (Pentacam, Oculus) of 20 eyes with keratoconus performed before and after corneal CXL were included into retrospective analysis. Mean follow-up was 2 years. Changes in(More)
Due to an increasing awareness of the potential hazardousness of air pollutants, new laws, rules and guidelines have recently been implemented globally. In this respect, numerous studies have addressed traffic-related exposure to particulate matter using stationary technology so far. By contrast, only few studies used the advanced technology of mobile(More)
