The invention provides a foldable intraocular-foreign-body containing device. The foldable intraocular-foreign-body containing device comprises a sleeve, a handle support and a containing bag. The sleeve is of a hollow cylindrical structure; the containing bag is fixed to one end of the handle support, and is of a foldable structure; the body structure of the handle support is arranged inside the sleeve and can slide front and back along the sleeve, and the containing bag is embedded into the sleeve when in a folded state. The foldable intraocular-foreign-body containing device is ingenious in structural design, the foldable containing bag is adopted, the 23G sleeve extends into eyes, foreign bodies are put into the containing bag and taken out, it is avoided that the foreign bodies fall off again in a secondary mode to injure the retina, the operation step is simplified, the operative complications are reduced, and the foldable intraocular-foreign-body containing device is of great significance in clinical practice.
