Silicone stents are routinely used for the maintenance of patent mucosal passages in patients with nasolacrimal disorders. A common complication associated with the use of silicone stents is lateral migration or displacement of the tubes, which can be difficult to correct. This report describes a modified Quickert-Dryden approach with fixation of the tubes by an intrasac suture. From 1990 to 19...

AIM: To investigate the feasibility of endoscopic dacryocystorhinostomy (En-DCR) with bicanalicular silicone tube intubation for treating chronic dacryocystitis secondary to nasolacrimal duct stent (NDS) incarceration. METHODS: En-DCRs were performed on 44 patients (46 eyes) NDS incarceration from April 2016 October 2022. The granuloma and scar tissues separated, removal was achieved during sur...

The leading cause of anesthesia-related injury is the inability to intubate the trachea and secure the airway.1 Improvements in video and optical laryngoscopy have allowed to obtain an indirect view of the glottis in a more simple way but sometimes this advantage occurs together with a difficult or impossible endotracheal tube (ETT) insertion.2 This is because indirect techniques do not require...

purpose: to evaluate the efficacy of silicone oil injection after deep vitrectomy in infectious endophthalmitis regarding visual acuity. methods: this single-blind randomized clinical trial was performed on 50 cases of infectious endophthalmitis undergoing deep vitrectomy. patients were randomly assigned to two groups: in one group silicone oil was injected into the eye at the end of the operat...

OBJECTIVE To determine whether prior silicone injection increases the risks associated with carbon dioxide laser resurfacing. DESIGN Laboratory determination of the effect of laser energy on liquid silicone; histologic evaluation of silicone-injected skin after lasing; and histologic demonstration of silicone deposits in all layers of dermis years after injection of silicone as filler fluid. ...

PURPOSE To evaluate surface properties of various intraocular lenses (IOLs), including a newly fabricated heparin-surface-modified (HSM) silicone IOL, with special reference to their efficiency in reducing potential silicone oil adherence to the IOL optics. SETTING Center for Research on Ocular Therapeutics and Biodevices, Department of Ophthalmology, Storm Eye Institute, Medical University o...

PURPOSE To determine the interaction of heavy silicone oil with various intraocular lens (IOL) materials and whether heavy silicone oil covers the silicone IOL optic as silicone oil does. SETTING Department of Ophthalmology, Dokuz Eylul University, Izmir, Turkey. METHODS The study group comprised 5 poly(methyl methacrylate) (PMMA) IOLs, 4 foldable silicone IOLs, 5 foldable hydrophilic acryl...
