Patent
CA 2403516
The present invention relates to compositions comprising polysiloxanes suitable for the preparation of accommodating intraocular lenses, having a specific gravity of greater than about 1.0, a refractive index suitable for restoring the refractive power of the natural crystalline lens and a viscosity suitable for injection through a standard cannula. The present invention includes intraocular lenses made from said polysiloxane compositions having a Young's modulus less than about 10 kPa.
L'invention concerne des compositions contenant des polysiloxanes, lesquelles conviennent à la préparation de lentilles intraoculaires et présentent une gravité spécifique plus grande que environ 1, un indice de réfraction convenant à la restauration du pouvoir de réfraction du cristallin et une viscosité convenant à leur injection à travers une canule normalisée. L'invention concerne également des lentilles intraoculaires constituées desdites compositions de polysiloxane, lesquelles lentilles présentent un module d'élasticité inférieur à environ 10 kPa.
