Abstract
An ophthalmic viscoelastic device includes at least one viscoelastic polymer, wherein the at least one viscoelastic polymer is cleavable into polymer chains of lower molecular weight, wherein the at least one viscoelastic polymer includes at least two polymer chains bonded to one another via at least one thermally and/or photochemically cleavable group, and wherein the at least one thermally and/or photochemically cleavable group is selected from compounds that can be coupled by a [2+2] cycloaddition and/or by click chemistry.
