Corneal penetrating injuries usually affect vision. Corneal puncture injuries are one of the more common types of eye injuries, usually caused by a sharp object that pierces the cornea. If the sharp object pierces the cornea further into the eye, it can cause iris damage, lens damage, and even retinal damage, all of which can destroy the structure of the eye and affect the patient’s vision. Even for simple corneal penetrating injury, after healing, it will leave scar on the cornea, affecting the transparency of the cornea, which will cause interference with vision. If the corneal penetrating injury is combined with infection, it will seriously jeopardize the patient’s vision, and may even lead to blindness due to uncontrollable endophthalmitis. Therefore, we should pay attention to prevention to avoid its occurrence, after the cornea is pierced by the injury, it is recommended to consult a doctor in order to minimize the damage to vision.
