A worm that has flown into the eye needs to be actively removed before it can be removed. First, rinse at home with clean water, preferably sterile saline, but if not, you can also use boiled cool white water for rinsing. If there is still a distinct foreign body sensation after flushing and tearing, it means that the worms may not be out yet, and this situation needs to be actively treated in the hospital. Forced treatment at home may lead to corneal damage. If you go to the hospital, the doctor can turn over the eyelid under the slit lamp, you will be able to find the location of the worm and remove it under the microscope without causing damage to the cornea, and you can target the conjunctival sac for rinsing. Secondly, anti-inflammatory eye drops can be used to prevent infection, and if damage is found at the corneal level you can also use nutritional corneal drugs, such as calf blood deprotein extract eye gel to promote healing of the corneal epithelium, along with levofloxacin eye drops for anti-inflammatory treatment.
