Mod\u00e8le mol\u00e9culaire innovant pour une nouvelle g\u00e9n\u00e9ration d\u2019huiles de silicone<\/strong><\/h3>\n

Gr\u00e2ce \u00e0 leur structure mol\u00e9culaire sp\u00e9ciale, le Siluron\u00ae<\/sup> Xtra et le Siluron\u00ae<\/sup> 2000<\/a><\/strong> pr\u00e9sentent, in vitro, une r\u00e9sistance \u00e9lev\u00e9e \u00e0 l\u2019\u00e9mulsification<\/strong>, par comparaison avec les huiles de silicone standards. Ces deux huiles de silicone innovantes se composent d\u2019un m\u00e9lange de cha\u00eenes mol\u00e9culaire ultralongues<\/strong> d\u2019une viscosit\u00e9 de l\u2019ordre de 2\u202f500\u202f000 mPa.s et de cha\u00eenes mol\u00e9culaires courtes d\u2019une viscosit\u00e9 de l\u2019ordre de 1\u202f000 mPa.s.<\/p>\n

Cet agencement mol\u00e9culaire sp\u00e9cial permet au Siluron\u00ae<\/sup> Xtra et au Siluron\u00ae<\/sup> 2000<\/a><\/strong>\u00a0d\u2019ajuster leurs propri\u00e9t\u00e9s visqueuses aux forces de cisaillement \u00e9lev\u00e9es et permanentes<\/strong>, g\u00e9n\u00e9r\u00e9es dans l\u2019\u0153il par les mouvements constants:<\/p>\n

Plus la force de cisaillement appliqu\u00e9e est importante, plus l\u2019huile de silicone se comporte de mani\u00e8re visqueuse, c\u2019est-\u00e0-dire plus elle est r\u00e9sistante \u00e0 l\u2019\u00e9mulsification<\/strong>. Les huiles conventionnelles, elles, au contraire, voient leur viscosit\u00e9 diminuer en continu sous l\u2019effet des forces externes constantes ce qui augmente leur tendance \u00e0 l\u2019\u00e9mulsification.<\/p>\n

La nouvelle g\u00e9n\u00e9ration d\u2019huiles de silicone \u2013 le Siluron\u00ae<\/sup> 2000<\/a><\/strong>\u00a0et le Siluron\u00ae<\/sup> Xtra \u2013 se caract\u00e9rise par sa r\u00e9sistance \u00e0 l\u2019\u00e9mulsification<\/strong> nettement plus \u00e9lev\u00e9e. Cette propri\u00e9t\u00e9 sp\u00e9cifique repose sur un m\u00e9lange intelligent de cha\u00eenes mol\u00e9culaires de longueurs diff\u00e9rentes et la viscosit\u00e9 dynamique en r\u00e9sultant. Leur bonne injectabilit\u00e9 \u00e0 travers de petites incisions constitue un autre avantage de ces huiles de silicone innovantes.<\/p>\n

Utilisation<\/h4>\n

Le Siluron\u00ae<\/sup> Xtra est utilis\u00e9 comme tamponnade de longue dur\u00e9e <\/strong>apr\u00e8s une intervention chirurgicale pour les d\u00e9collements r\u00e9tinien s\u00e9v\u00e8res, en particulier dans les cas de:<\/p>\n

    \n
  • D\u00e9collement r\u00e9tinien avec d\u00e9chirure importante<\/li>\n
  • D\u00e9collement r\u00e9tinien associ\u00e9 \u00e0 une prolif\u00e9ration vitr\u00e9o-r\u00e9tinienne (PVR)<\/li>\n
  • D\u00e9collement r\u00e9tinien associ\u00e9 une r\u00e9tinopathie diab\u00e9tique prolif\u00e9rante (RDP)<\/li>\n
  • D\u00e9collement r\u00e9tinien traumatique<\/li>\n<\/ul>\n
