The invention discloses an ophthalmic flushing device for preventing a cleaning liquid from flowing to the ear canal, nasal cavity or neck. The bottom of a sliding wall is slidably connected to the top surface of a soft plastic partition, the bottom of which is fixedly connected with soft plastic. The top of the inner wall of the sliding wall is fixedly connected with the top of the side wall of atelescopic groove. The outer port of the telescopic groove is fixedly connected with a connecting rod. The side wall of the telescopic groove is provided with a passage port, which penetrates one endof a telescopic pipe. The other end of the telescopic pipe penetrates the inside of a pipe at the bottom of the telescopic groove. According to the difference of human body data, the manufacturing size of the internal opening and closing size of the soft plastic is larger than the conventional size of the human eye, which can solve the problem of the size difference of human eyes. The sliding wall is set as the shape of a slope, which is convenient for the liquid to slide into an arc-shaped channel so as to avoid residues and can also successfully help complete the eye cleaning so as to prevent the cleaning liquid from flowing to the position outside the eye.
