[en] 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.
