A process for producing polysiloxane prepolymers of improved homogeneity 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 de production de prépolymères de polysiloxane à homogénéité améliorée de manière à produire des compositions polymères à indice de réfraction relativement élevé. Les compositions polymères ainsi produites sont utilisées dans la production de dispositifs ophtalmiques tels que, par exemple, des lentilles intra-oculaires et des implants cornéens.
