Alkaline water in the eye is most likely to cause chemical eye trauma, most commonly resulting in corneal epithelial damage. When alkaline enters the eye, it is recommended that a large flush of the conjunctival sac be performed immediately with clean tap water close by. Immediately after flushing, go to the nearest eye hospital and perform a high dose flush with saline in the ophthalmology department for at least half an hour, using at least 1000 ml of saline. After flushing, a detailed examination under a slit lamp is performed to check the extent of damage to the corneal epithelium, and the relevant treatment is performed according to the extent of damage to the corneal epithelium. Anti-infective eye solutions such as levofloxacin eye solution can be used prophylactically to fight infection because once the corneal epithelium is damaged, keratitis and even corneal ulcers can easily occur. Medications that promote corneal epithelial repair, such as fibroblast growth factor ophthalmic gel and calf blood deprotein ophthalmic gel, can also be used.
