1. a topical ophthalmic multiple dose Aquo-composition comprises:

  • The viscosity that comprises following component strengthens system;

    I) dissipation type viscosity intensifier, it demonstrates the viscosity of enhancing when compositions being applied to the eye surface of human eye, but then dissipates and lose gradually thereafter viscosity;

    WithIi) temperature-sensitive phase transformation viscosity intensifier, it demonstrates lower viscosity when compositions being applied to the eye surface of human eye, but then after being applied to the eye surface of eyes, demonstrates the viscosity of enhancing;

    And water.
