Fractionated oil (Rumex) SmartSil www.rumex.net 6 Silicone Oil SmartSil 1000/5000 SmartSil 1000/5000 is an ultra purified silicone oil which leads a maximum interactions between tissues, cells and endotamponades media. The physical properties include a combination of specific gravity, refractive index and surface tension. The choice of viscosity offers an optimum balance between easy injection and a stable temporary tamponade. SmartSil 1000/5000 is designed for the retinal endotamponade after vitrectomy. www.rumex.net 7 SmartSil 1000, SmartSil 5000

Appearance : viscous, transparent, odorless liquid Formula : POLYDIMETHYLSILOXANE www.rumex.net 8 Exclusive Purification Vacuum molecular distillation purification of the RUMEX Int. LTD. Silicone oil: * Solvent free purification * Potentially toxic low molecular weight oligomers (D_4 to D_20) extraction * Residual volatile components extraction (water, ethanol, ) Post-purification controls: * Gel permeation chromatography (GPC) * Gaseous chromatography (GC) www.rumex.net 9 Emulsification Implantation time

There is no recommend implantation time for the silicone oil. The implantation duration must be controlled and adapted to the retinal state of the patient Emulsification Rumex silicone oil has proven an excellent stability and optimal transparency because of its exclusive vacuum molecular distillation purification. No solvent are used, potentially toxic low molecular weight and residual volatile components (water , ethanol) that could lead to emulsification are extracted in the purification process. www.rumex.net 10 Purification process PURIFICATION PROCESS: Because the silicone oil replaces the vitreous , it must be clear and transparent in order to let both the patient and the surgeons see through it. One of the main risk after injecting silicone oil is to see it becoming opaque because of an emulsification process. In order to avoid any emulsification risk, the purification process is a key element for the manufacture of a safe and reliable silicone oil. This is why Rumex silicone oil purification process is unique: it is called vacuum molecular distillation purification. The purification process aims to get rid of the low molecular weight oligomers which might cause an emulsification . Usually, our competitors are adding some solvents like

ethanol in order to remove the low molecular weight oligomers. After, they rinse the solvent with water in order to remove it from the silicone oil. While doing this, they take a double risk: the first risk is to leave some solvent in the silicone oil, which is very toxic. The second risk is to leave some water in the silicone oil: water might cause emulsification of the oil. The Rumex vacuum molecular distillation purification process does not use any water or solvent; in fact this process removes the low molecular weight oligomers without adding any substance to the silicone oil. This is why we think our silicone oil is one of the purest available on the market. No emulsification shall occur when doctor will use the recommendation mentioned in the instructions for use. www.rumex.net 11 Purification www.rumex.net 12 Indications SMARTSIL is indicated in prolonged tamponade

after surgical treatment for severe retinal detachment, especially: retinal detachment with proliferative vitreoretinopathy retinal detachment that complicate a diabetic retinopathy retinal detachment with giant tears traumatic retinal detachment secondary retinal detachment to a viral retinitis www.rumex.net 13 Packaging SMARTSIL is supplied sterile. It is dry heat sterilized in its primary packaging (syringe). This is then packaged in a pouch for a steam sterilization, to make it easier to handle in aseptic conditions. Our purification process guarantees a pure silicone oil, free of low molecular weight components and synthesis residues. SMARTSIL is a single-use liquid and must not be resterilized. www.rumex.net
