Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...

BACKGROUND Coated polyglactin 910 suture with triclosan was developed recently in order to imbue the parent suture, coated polyglactin 910, with antibacterial activity against the most common organisms that cause surgical site infections (SSI). Because such alterations could alter the physical properties of the suture, this study sought to compare the intraoperative handling and wound healing c...

Several surgeons advise a variety of tip sutures and describe their own techniques in open approach. Septocolumellar suture is one of them and can be described as a loop suture between the medial crura and caudal septum. Although some of the articles mention that it can be applied in closed rhinoplasty, there is no description of the technical details. This paper presents indications, technical...

Objective: Peripheral nerve transection causes neuonal cell death. Effects of surgical nerve repair on survival of primary sensory neurons was to be studied. Methodology: This is a morphometeric study of dorsal root ganglion neurons of adult rats by Hoechst staining conducted at Neuroscience laboratory and Cellular and Molecular Center, Medical faculty, Iran University of Medical Sciences. Mode...

PURPOSE The purpose of this study was to evaluate the mechanical performance of different suture locking mechanisms including: i) interference fit between the anchor and the bone (eg, 4.5 mm PushLock, 5.5 mm SwiveLock), ii) internal locking mechanism within the anchor itself (eg, 5.5 mm SpeedScrew), or iii) a combination of interference fit and internal locking (eg, 4.5 mm MultiFIX P, 5.5 mm Mu...

PURPOSE Intraocular pressure and aqueous humor flow direction determined by the scleral flap immediately after trabeculectomy are critical determinants of the surgical outcome. We used a large-scale model to objectively measure the influence of flap thickness and shape, and suture number and position on pressure difference across the flap and flow of fluid underneath it. METHODS The model exp...

PURPOSE We previously demonstrated that selective suture removal reduces keratoplasty astigmatism; however, a myopic shift was induced with increasing number of interrupted sutures removed. This study is an attempt to determine the effects of a modified surgical technique on postkeratoplasty myopia, astigmatism, and anisometropia. METHODS Optical penetrating keratoplasties were performed on 9...

Closure of donor site of the flap has special problems. Reduction of this site will decrease the morbidity of operation. In this study, we present our experience in donor site size reduction. METHODS Between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. In all patients, coverage of defect was performed with various flaps. Substratum horizontal mat-tress sut...

BACKGROUND/OBJECTIVE The aim of this study was to investigate the effects of different concentrations of ozone (O3) therapy on bone regeneration in response to an expansion of the inter-premaxillary suture in rats. MATERIALS AND METHODS Forty-eight Wistar rats were randomly divided into four groups (n = 12). In groups I, II, and III, 1ml of O3 at 10, 25, and 40 µg/ml was injected at the prema...
