A method for replacing ocular fluid in a mammalian eye by introducing an aqueous solution of a water soluble hydrogel forming polyether polyurethane in an amount of 0.5 to 7.0% weight of said polymer percent, said polyether polyurethane is prepared by reacting at a NCO/OH ratio of from about 0.8 to about 1.2, said polyether polyurethane is prepared by mixing a diisocyanate with a glycol component comprising one or more polyoxyethylene glycols, optionally mixed with one or more lower molecular weight ethylene glycols the total glycol component having an average molecular weight of from about 1,000 to about 20,000 and mixing the reaction product in an aqueous medium wherein there are no adverse effects to eyes so treated. A method for replacing intra-articular fluid in a mammalian joint by directly introducing into said joint an aqueous solution of a water soluble hydrogel forming polyether polyurethane in an amount of 0.5 to 7.0% weight percent of said polymer said polyether polyurethane is prepared by reacting at a NCO/OH ratio of from about 0.3 to about 0.85, said polyether polyurethane is prepared by mixing a diisocyanate with a glycol component comprising one or more polyoxyethylene glycols, optionally mixed with one or more lower molecular weight ethylene glycols the total glycol component having an average molecular weight of from about 1,000 to about 20,000 and mixing the reaction product in an aqueous medium wherein relief of arthritic symptoms is provided.
