Enhanced vertical bone augmentation in rat parietal bone using hydroxyapatite-coated polytetrafluoroethylene domes with Erbium Yttrium Aluminum Garnet pulsed laser deposition.
J Prosthodont Res
January 2025
Department of Orthodontics, Osaka Dental University, Hirakata, Japan.
Purpose: To perform vertical bone augmentation on rat parietal bone by coating the inner surface of dense polytetrafluoroethylene (d-PTFE) domes with hydroxyapatite (HA) using Erbium Yttrium Aluminum Garnet (Er:YAG) pulsed laser deposition in a rat model.
Methods: The d-PTFE plate surface, α-tricalcium phosphate (α-TCP) coating, and HA coating were measured using scanning electron microscopy and X-ray diffraction to confirm the replacement of α-TCP with HA via high-pressure steam sterilization. The dome was glued to the center of the rat parietal bone and closed with periosteal and epithelial sutures.
Comparative Analysis of Effective Lens Position and Refractive Outcomes in Scleral-Fixated versus Intracapsular Intraocular Lenses.
Clin Ophthalmol
December 2024
Department of Ophthalmology, Visual and Anatomical Sciences, Kresge Eye Institute/Wayne State University School of Medicine, Detroit, MI, USA.
Purpose: To evaluate the outcomes of scleral-fixated intraocular lenses (IOLs) implanted using either Yamane technique or Gore-Tex suture fixation, in comparison to intracapsular lens fixation, and to assess the efficacy of various lens formulas in achieving predicted refractive targets.
Patients And Methods: This study included 45 eyes from 44 patients with scleral-fixated IOLs, comprising 37 Yamane eyes and 8 Gore-Tex eyes. Preoperative refractive predictions from various formulae were compared with final postoperative refraction.
Introduction: The aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (PCIOLs) and to demonstrate a method for validating the lens position.
Methods: Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).
Scleral fixated intraocular lens techniques for the vitreoretinal surgeon: an update.
Curr Opin Ophthalmol
December 2024
Department of Research, Wills Eye Hospital, Philadelphia, PA.
Purpose Of Review: To describe recent evidence regarding surgical techniques for secondary scleral fixation of intraocular lenses (IOLs), with attention to information most relevant to the surgical practice of vitreoretinal surgeons.
Recent Findings: Recent studies have reported favorable outcomes in patients treated with scleral fixation of IOLs using Gore-Tex suture and flanged intrascleral haptic fixation (ISHF). ISHF can be achieved using trocar-cannulas or double needle-based techniques.
New Concepts in Circumareolar Mastopexy: The "Star Interlocking Suture"-A Case Series.
Aesthetic Plast Surg

Unit of Plastic Surgery, University "Federico II", Via Sergio Pansini, 5, 80131, Naples, Italy.
The circumareolar approach is one of the most popular and versatile in breast surgeries. Nevertheless, this approach usually implies a closure under tension which could lead to areolar distortion, scar widening and hypertrophic scarring. To prevent these complications, different surgical adjustments to this technique have been proposed, such as the Hammond's "Interlocking Gore-Tex suture.
