After the cornea is damaged, the eyes should be closed as much as possible during the repair process. After corneal damage, it will stimulate the sensory nerve fibers in the corneal tissue, which will cause strong foreign body sensation, tingling sensation, photophobia, tearing and vision loss, etc. Patients should go to the ophthalmology department of the hospital in time, and be examined by the doctor using a slit-lamp microscope to diagnose the severity of the damage. After the diagnosis is clear, medication that promotes corneal repair, such as recombinant human epidermal growth factor drops, can be prescribed. In the process of repair, you should rest with your eyes closed. Opening your eyes and blinking will repeatedly rub the corneal wound, which is not conducive to the repair of corneal injuries, and keeping your eyes closed has a protective effect on the corneal wound, which can promote the repair of the injury. During the process of trauma repair, regular review should be conducted by the doctor to observe the condition of corneal wound repair, for example, to observe whether the area of the corneal wound has been reduced and whether there is any local infection.
