After corneal epithelial injury, it is usually necessary to wrap the eye with gauze for about 1~2 days, the purpose of which is to let the patient close his eyes and rest as much as possible, so as to avoid rubbing the cornea due to the rotation of the eyeballs as well as blinking, which will delay the healing time of the corneal epithelium. Corneal epithelial injury is a common disease in ophthalmology, which is usually caused by rubbing the eye, entering foreign objects in the eye, etc. It will lead to symptoms such as redness of the eye, eye pain, photophobia, tearing, and loss of vision. Diagnosis can be confirmed by a doctor through a slit lamp microscopic examination, followed by medication to promote corneal repair, such as recombinant bovine basic fibroblast growth factor eye drops, etc., and antibiotic drops to prevent infection, such as ofloxacin eye drops, etc., under the guidance of the doctor. Usually, gauze can be wrapped around the eye to limit the patient’s ability to see, and keep the eye closed as much as possible to promote corneal epithelial repair, so as to avoid repeated friction between the corneal epithelial injury and the eyelid, which may delay the healing process.
