PURPOSE The purpose of this study is to compare the adhesion capabilities of the most important etiologic agents of microbial ocular infection to the recently available silicone-hydrogel lenses with those to a conventional hydrogel lens. METHODS In vitro static adhesion assays of Pseudomonas aeruginosa 10,145, Staphylococcus epidermidis 9142 (biofilm-positive), and 12,228 (biofilm-negative) t...

Silicone gel from ruptured implants can migrate to locations such as the chest wall, axillae, and upper extremities, resulting in granulomatous inflammation. Pleural silicone granulomas have rarely been reported in the literature. This is a rare case of pleural silicone granuloma, which demonstrates that silicone gel from an extracapsular implant rupture can fistulise into the pleural space alo...

This paper presents the successful fabrication of a transparent electrode comprising a sandwich structure of silicone/Ag nanowires (AgNWs)/silicone equipped with Diels-Alder (DA) adducts as crosslinkers to realise highly stable stretchability. Because of the reversible DA reaction, the crosslinked silicone successfully bonds with the silicone overcoat, which should completely seal the electrode...

AIM The complications of intraocular silicone oil include emulsification, which may lead to vision-threatening disorders such as keratopathy, secondary glaucoma and retinopathy. The authors study the effect of mechanical energy from surgical instruments on the emulsification of silicone oil. METHODS Three different handpieces (phacofragmentation, phacoemulsification, high-speed vitrectomy) we...

purpose: to evaluate the success rate of bicanalicular silicone tube intubation in children with congenital nasolacrimal duct obstruction (cnldo). methods: hospital records of 71 cases of bicanalicular silicone intubation in 62 children with cnldo were reviewed. success was defined as resolution of symptoms and signs such as epiphora and discharge 6 months after removal of the silicone tube. re...

This paper presents the transient solution of a variant working vacation queue with balking. Customers arrive according to a Poisson process and decide to join the queue with probability $b$ or balk with $bar{b} = 1-b$. As soon as the system becomes empty, the server takes working vacation. The service times during regular busy period and working vacation period, and vacation times are assumed ...

PURPOSE To evaluate electroretinogram (ERG) changes after silicone oil removal. METHODS Scotopic and photopic ERGs, and best-corrected visual acuity (BCVA) were checked before and shortly after silicone oil removal in eyes that had previously undergone vitrectomy and silicone oil injection for complex retinal detachment. Pre- and postoperative ERG a- and b-wave amplitudes were compared. RES...

Silicone elastomers play a crucial role in the field of maxillofacial prosthodontics. To maintain optimal hygiene, various disinfectants have been reported to clean silicone prostheses. Nevertheless, when selecting disinfectant, it is important consider not only its antimicrobial efficacy, but also compatibility with materials, minimize any potential impact on physical properties material surfa...

Cerebrospinal fluid (CSF) shunts for the treatment of hydrocephalus are generally made of silicone rubber. The growth of bacterial colonies on the silicone surface leads to frequent CSF shunt complications. A systematic study of the effect of the surface modification of silicone on Staphylococcus epidermidis adhesion and colonization was performed for different incubation times by means of colo...
