The objective of this report is to demonstrate the effectiveness of an iris prosthesis to treat a refractory glaucoma induced by silicone oil in the anterior chamber. This case is about a patient who suffered a trauma caused by firearm shrapnel. A vitreous-retinal surgery was performed to remove intraocular foreign matter and to realign the retina that was detached. Due to the partial traumatic...

Abstract In this paper, three kinds of silicone rubber materials, methyl rubber, phenyl and fluorosilicone are used as the research object, contact angle tester, thermal conductivity insulation resistance differential scanning calorimeter thermogravimetric analyzer to explore effect side groups on properties rubber. The results show that materials is poor, but they all have good hydrophobicity,...

We describe a case of femtosecond laser-assisted cataract surgery (FLACS) in an eye with multiple comorbidities, including retinal detachment surgery, high myopia, posterior chamber phakic intraocular lens (PC pIOL) and residual, emulsified, silicone oil located in the anterior chamber. FLACS was affected by the optical blockage, but the incomplete capsular tear was recoverable. The case sugges...

The silicone elastomer microvascular casting method is readily adaptable for study of most microcirculatory beds. These perfusion materials are not acutely toxic to the microcirculation. The basic microvascular geometry can be profitably studied with this method and it demonstrates a pattern of right-angle branching in the lung, a manifold pattern at the inflow of the renal glomerulus, and a we...

____________ _ Pump head tubing was studied to determine if internal wear occurred during routine cardiopulmonary bypass. Several segments of silicone rubber tubing were examined in a scanning electron microscope following clinical perfusion. In each case, the proper degree of occlusion had been set just prior to beginning bypass. The roller pump was a six-inch dual roller type, and the tubing ...

BACKGROUND Substrates in medical science are hydrophilic polymers undergoing volume expansion when exposed to culture medium that influenced on cell attachment. Although crosslinking by chemical agents could reduce water uptake and promote mechanical properties, these networks would release crosslinking agents. In order to overcome this weakness, silicone rubber is used and reinforced by nanocl...

The pH dependency of permeation of weak electrolytes allows inferences to be made about the barrier characteristics of membranes. The influences of enhancers on pH-permeation profiles promise further mechanistic enlightenment. To explore issues of weak electrolyte mass transfer, a steady-state mathematical model for a hydrophobic membrane with aqueous pores existing in series with aqueous phase...

A cheap and fast method of providing long term accommodating insoles is described. Room temperature vulcanizing (RTV) silicone rubber is used, with suitable coverings, to provide pain relief and support for feet and ankles. The combination of physical properties of the finished item provides a useful balance between support and flexibility which results in these insoles being readily accepted b...

A device is described which consists of a bonded Plexiglas-silicone rubber plate, perforated to hold capillary pipettes in register with the wells of a plastic tray to be inoculated. Pipette contents are simultaneously discharged by positive air pressure, initiated by closing an exhaust port with the thumb.
