After getting foam in the eyes, patients need to avoid rubbing the eyes, rinse the eyes with running water, and use medication as prescribed by the doctor. Foam is a chemical material that may irritate the eyes with congestion, stinging, tearing, and other discomforts when it enters the eyes. Patients need to avoid having to rub their eyes with their hands, or else the cornea may be damaged by contact between the foreign material and the eye. Secondly, the bacteria on the hands are very high and can enter the eyes through this eye rubbing action, causing bacterial infection and leading to conjunctivitis. When the foam enters the eye, the eye can be rinsed with running water or purified water to dilute the foam concentration and relieve the irritation of the eye. Patients can also follow the doctor’s prescription medication, such as levofloxacin hydrochloride eye drops, azithromycin eye drops, etc., to prevent infection. It is recommended that patients with foreign bodies in their eyes seek prompt medical attention to assess their condition and follow doctor’s instructions for treatment.
