A hydrogel composition comprises water and a hydrophilic polymer, and has (a) an ultimate tensile strength of about 10 kPa or more, (b) a compressive strength of about 70 kPa or more, or (c) an ultimate tensile strength of about 10 kPa or more and a compressive strength of about 70 kPa or more. A method of producing a hydrogel composition involves providing a compression mould having an internal volume, providing a hydrogel precursor comprising a melt-processable, radiation crosslinkable, hydrophilic polymer, filling at least a portion of the internal volume of the compression mould with the precursor, compressing the precursor contained within the compression mould to form a moulded body therefrom, irradiating at least a portion of the moulded body to crosslink at least a portion of the hydrophilic polymer contained within the moulded body, and hydrating the irradiated moulded body to form a hydrogel therefrom.
