The invention provides preparation and application of medical hydrophilic organic silicon oil, and relates to the technical field of organic silicon oil preparation. The invention relates to a methodfor preparing medical hydrophilic organic silicon oil, which comprises the following steps: S1, adding dimethyl cyclosiloxane and hexamethyldisiloxane into dehydrated toluene in parts by weight, carrying out stirring operation, controlling the stirring reaction time to be 0.5-2 hours, and slowly dropwise adding distilled water and concentrated sulfuric acid with stirring to obtain a reaction product A, wherein the stirring reaction time is controlled at 1-2 h; then cleaning the reaction product A with a sodium bicarbonate aqueous solution until the reaction product A is neutral, and removing low molecules through reduced pressure distillation to obtain colorless and transparent organic silicone oil. The polyether modified organic silicon oil produced by the reasonable preparation method has the characteristics of
