Eye penetration is complex and severe, and the ability to save the eye is related to the site and extent of the wound and the degree of injury and the presence of complications. In the case of corneal linear wounds with good alignment, no embedded ocular contents, and the presence of the anterior chamber, the eyeball can usually be saved. In corneoscleral wounds with uveal prolapse, after debridement, suturing, and prevention of complications such as infection, the eyeball can usually be saved as well. In severe penetrating eye injuries, where the eyeball is severely damaged and there is no hope of restoring visual function, or where treatment of intraocular infection is ineffective and light perception is lost, the eyeball has no value for preservation. After the occurrence of eye penetration, the injured eye should be protected, no pressure should be applied, go to the hospital as soon as possible, and standardize the treatment under the guidance of the doctor.
