Aim: The aim of this study was to compare the pre- and posttreatment corneal densitometry and corneal thickness value of keratoconus (KCN) patients managed via contact lenses (CLs) or by both intrastromal corneal rings and contact lenses. Patients and methods: This prospective study was performed at the Manchester Royal Eye Hospital, UK. Patients were recruited before treatment and followed up for 12 months. Data of corneal densitometry and corneal thickness were collected using the Oculus Pentacam at the pretreatment visit and posttreatment visit at 12 months...

Purpose: Keratoconus is a progressive disease of the cornea which can lead to blindness as irregular astigmatism increases. Currently, a variety of methods are available for the treatment of keratoconus, and in certain cases, it may be difficult to choose the most appropriate option. This article reviews available treatment modalities for keratoconus to provide the practitioner with practical and useful information for selecting the most suitable option for each individual patient. Methods: To review treatment methods for different stages of keratoconus, PubMed (United States National Library of Medicine) and Scopus (Elsevier BV) databases were searched using the keywords "keratoconus", "contact lens", "cross-linking", "Intacs", "keratoplasty", "gene therapy", and "irregular astigmatism", and related articles were reviewed based on disease assessment parameters and treatment methods...

This study was performed to evaluate the visual, refractive, and aberration measurement results of 2 implants, including Intacs Intracorneal Ring Segments (ICRS) and phakic Toric Implantable Collamer Lens (TICL), in patients with moderate Keratoconus (KCN). In this retrospective cross-sectional study, 30 patients with KCN with a mean age of 29.83 years were included in 2 groups, including the Intacs Intracorneal Ring Segments (ICRS) group and the phakic Toric Implantable Collamer Lens (TICL) group. Preoperative data as well as 6-month, 1-, 2-, 3- and 4-year follow-up data after the operation were collected and analyzed with the SPSS software (ver...

PURPOSE: To evaluate the outcome of additional KeraRing (Mediphacos, Belo Horizonte, Brazil) implantation in patients with keratoconus with previously implanted INTACS (Addition Technology Inc, Fremont, CA) segments. METHODS: The KeraRing was implanted in 5 eyes of 3 patients with keratoconus without removal of previous intrastromal corneal ring segments. Tunnels were created manually. Snellen uncorrected distance visual acuity (UDVA), corrected distance visual acuity, refractive and keratometric values, and higher-order aberrations were recorded before and after KeraRing implantation...

BACKGROUND: To report the use of scleral lens (ScCL) to improve vision in patients having keratoconus who had intracorneal ring segment (ICRS) surgery. METHODS: Two eyes of two keratoconus patients fitted with ScCL (PROSE - prosthetic replacement of the ocular surface ecosystem, USA) after having undergone ICRS surgery are reported as noncomparative interventional case series. The ICRS implanted were INTACs and kerarings. Indications, visual acuity with ScCL, complications and follow-up are reported...

BACKGROUND: This study evaluated the use of an autologous vein graft, supported by expanded polytetrafluoroethylene (ePTFE) chordae tendineae, to replace an anterior mitral valve leaflet. METHODS: A double-layered autologous jugular vein graft, supported by ePTFE chords, was used to create an anterior mitral valve leaflet in 21 sheep. Mitral valve function was monitored with echocardiography for up to 10 months. Surviving sheep were euthanized between 6 and 10 months later, and vein implants were examined histologically...

Xiaojing Teng, Shuhong Zhang, Wei Liu, Kuo Bi, Lei Zhang
Fluorescence in situ hybridisation (FISH) is a molecular cytogenetic technique, which is regularly applied to formalin-fixed paraffin-embedded (FFPE) tissue sections of a variety of cancers to assess chromosomal aberrations. However, high-quality FISH requires optimal enzymatic digestion, and insufficient digestion is not noted until the hybridisation signals are evaluated in the fluorescence microscope. As a consequence, FISH results may be unreliable, and the experiment might have to be repeated. To solve this problem, we developed a new method for real-time evaluation of enzymatic tissue digestion...

Ebola virus (EBOV), the causative pathogen of the deadly Ebola virus disease (EVD), can be transmitted via contact with EVD patients, including sexual contact with EVD survivors. At present, no licensed vaccine or therapeutic is available. In this study, we compared eight anhydride-modified proteins for their entry-inhibitory activity against the pseudovirus (PsV) carrying the envelope glycoprotein (GP) of the EBOV Zaire or Sudan species (Zaire PsV and Sudan PsV, respectively). We found that 3-hydroxyphthalic anhydride-modified human serum albumin (HP-HSA) was the most effective in inhibiting the entry of both Zaire PsV and Sudan PsV, with the 50% effective concentration being at the nanomolar level and with HP-HSA being more potent than EBOV-neutralizing antibody MIL77-2 (4G7, a component antibody of the ZMapp drug cocktail)...

Purpose. To evaluate surgically induced astigmatism (SIA) and the average corneal power change in symmetric intrastromal corneal ring segment (ICRS) implantation. Methods. The study included 34 eyes of 34 keratoconus patients who underwent symmetric Intacs SK ICRS implantation. The corneal pocket incision meridian was the preoperative steep meridian. Corneal power data were obtained before and 3 months after Intacs SK ICRS implantation using scanning-slit topography. Polar value analysis was used to evaluate the SIA...

INTRODUCTION: Ocular targeted therapy has enormously been advanced by implementation of new methods of drug delivery and targeting using implantable drug delivery systems (DDSs) or devices (DDDs), stimuli-responsive advanced biomaterials, multimodal nanomedicines, cell therapy modalities and medical bioMEMs. These technologies tackle several ocular diseases such as inflammation-based diseases (e.g., scleritis, keratitis, uveitis, iritis, conjunctivitis, chorioretinitis, choroiditis, retinitis, retinochoroiditis), ocular hypertension and neuropathy, age-related macular degeneration and mucopolysaccharidosis (MPS) due to accumulation of glycosaminoglycans (GAGs)...

BACKGROUND AND PURPOSE: Implantation of intracorneal ring segments (ICRS) using a femtosecond laser is a minimally invasive procedure which represents a reliable option to widen the spectrum of the stage-related therapy of keratoconus in patients with contact lens intolerance, or with post-LASIK-keratectasia or pellucide marginale degeneration (PMD). METHODS: From August 2011 to September 2015, 84 eyes of 69 patients were implanted with ICRS. 74 eyes were implanted with INTACS-SK (Intacs, Addition Technology, Inc...

PURPOSE: To report visual outcomes and corneal biomechanical changes after femtosecond-assisted Intacs SK implantation in keratoconic eyes. METHODS: This prospective interventional case series is comprised of 32 keratoconic eyes of 25 patients with mean age of 23.8 ± 5.4 years. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, refraction, manifest refraction spherical equivalent (MRSE), keratometry, central corneal thickness (CCT), corneal hysteresis (CH) and corneal resistance factor (CRF) were measured preoperatively, and 1, 3 and 6 months postoperatively...

The introduction of extended-release opioid analgesics helped initiate an epidemic of prescription opioid abuse in the United States. To make access to the drug by crushing or dissolution more difficult, abuse-deterrent formulations (ADFs) of OxyContin (Purdue Pharma, Stamford, CT) and Opana ER (Endo Pharmaceuticals Inc., Malvern, PA), which use the same foundation technology (Intac, Grunenthal, Aachen, Germany), were introduced in 2010 and 2012, respectively. To examine their relative effectiveness, we used a structured survey of 12,124 individuals entering treatment for opioid use disorder followed by a more focused online survey with a subset of these patients (N = 129) using both structured and open-ended questions...
