In vitro emulsification assessment of new silicone oils

AIM To investigate whether the emulsification of conventional silicone oils can be reduced by adding small amounts of silicone molecules of a very long chain length. METHODS Siluron 1000, Siluron 2000, Siluron 5000, Acri.Sil-Ol 5000, Oxane 5700, Densiron 68 LV, Densiron 68 and Densiron 68 HV (0.5 ml) were each tested along with either plasma or serum (0.5 ml) in a glass cuvette. Emulsificatio...

Development of emulsification-resistant silicone oils: can we go beyond 2000 mPas silicone oil?

PURPOSE To develop new blends of emulsification-resistant silicone oil based on high molecular weight (HMW) silicone oil for use as an endotamponade in vitreoretinal surgery. METHODS Viscosity and elasticity of various silicone oil blends (Siluron 1000, Siluron 2000, Siluron 5000, 7% HMW + Siluron 1000, 10% HMW + Siluron 1000, and 15% HMW + Siluron 1000; Fluoron GmbH, Ulm, Germany) were measu...

Emulsification tendency of silicone-phenylsilicone copolymer.

PURPOSE We compared the emulsification tendency of silicone-phenylsilicone copolymer (DPC; 5%-phenylated, specific gravity 0.984) with that of silicone oil (SO; specific gravity 0.966) and fluorosilicone oil (FSO; specific gravity 1.256), all of which are used clinically as intraocular tamponades. METHODS We investigated the tendencies of emulsification in SO, FSO, and DPC. Each was placed in...

Mechanical energy from intraocular instruments cause emulsification of silicone oil.

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...

The in vitro antimicrobial activity of silicone oils used in ophthalmic surgery.

BACKGROUND The aim of the study was in vitro assessment and comparison of the antimicrobial activity of three types of silicone oils used in ophthalmic surgery. METHODS The silicone oils (Arciolane 1300 centistokes, Arciolane 5500 centistokes and Oxane Hd, heavy silicone oil) were inoculated with microbes common in endophthalmitis and their growth was observed continuously. Control tests of m...
