If detergent enters the eye, the eye should be flushed with plenty of water, and the eyelid should be turned over and the eyeball rotated to flush out the detergent as much as possible. If the patient does not suffer from eye redness, foreign body sensation, photophobia, pain and other discomforts after rinsing, the next step of special treatment may not be required. If the patient continues to experience redness, foreign body sensation, tearing, photophobia and other discomforts after rinsing, a prompt visit to a regular eye care provider is required to determine the extent of corneal and conjunctival damage. If accompanied by defective corneal epithelium and damage to the corneal epithelium, it is necessary to apply levofloxacin eye drops, 1 drop 4 times daily, to prevent eye infection and recombinant bovine basic fibroblast growth factor eye drops, 1 drop 4 times daily, to promote the repair of corneal epithelium.
