A syringe is for an eye operation. The syringe has a syringe body, a plunger arranged in the syringe body so as to be displaceable in the syringe longitudinal direction, a viscoelastic chamber in which a viscoelastic is arranged, and a decomposition reagent chamber which is arranged separately from the viscoelastic chamber and in which a decomposition reagent is arranged for decomposing the viscoelastic. The syringe has a storage state, in which the viscoelastic and the decomposition reagent are arranged separately from one another, and a use state, into which the syringe is able to be put by longitudinally displacing the plunger and in which the viscoelastic and the decomposition reagent are mixed with one another.
