  The present invention relates an organic liquid composition comprising a mixture of a first polymer with a linear polymeric chain having two photoactive groups as endgroup; and a second polymer with a multifunctional polymeric chain having at least three photoactive groups, that can reversibly and repeatedly crosslink to form a solid polymer network wherein said liquid composition been crosslinked by irradiation with at least one wavelength L1 and been uncrosslinked at least locally by irradiating the network with at least one other wavelength L2 in order to repeatedly adjust shape and optical properties of said composition in its crosslinked state. The composition is applicable as a starting material for intraocular lenses and for other lenses and optical elements.

  本发明涉及一种有机液体组合物，该组合物包括第一聚合物和第二聚合物。其中，第一聚合物具有具有两个光活性基团的线性聚合物链作为末端基团；第二聚合物具有至少三个光活性基团的多功能聚合物链，可以可逆地和重复地交联形成固体聚合物网络。该液体组合物通过至少一种波长L1的辐射交联，并通过至少一种其他波长L2的辐射在局部至少解交联，以重复调整其交联状态下的形状和光学性能。该组合物适用于人工晶状体和其他透镜和光学元件的起始材料。
