A process for producing silicone-containing prepolymers capable of absorbing blue light for use in the production of relatively high refractive index polymeric compositions is described herein. Polymeric compositions so produced are useful in the production of ophthalmic devices such as for example intraocular lenses and corneal inlays.
L'invention concerne un procédé permettant de produire des prépolymères contenant du silicone capables d'absorber la lumière bleue et destinés à être utilisés dans la production de compositions polymères à indice de réfraction relativement élevé. Les compositions polymères ainsi obtenues sont utiles dans la production de dispositifs ophtalmologiques tels que des lentilles intraoculaires et des implants cornéens.
