The invention relates to a composition with sustained release kinetic a therapeutically effective amount of therapeutic agent intended for treating diseases or pathological conditions of eye for a subject needed such kind of treatment; at that, said compisiton is water-in-oil type emulsion compri¬sing an oil phase, lipophilic surfactant dissolved in the oil phase and aqueous phase, and hydrophilic therapeutic agent dissolved in the aqueous disper-sed phase. At that, said composition is intoruced intraoculary because has density less than 1.
