If ear drops are inadvertently used as eye drops, the eyes need to be rinsed immediately with water, followed by a visit to the ophthalmology department of the hospital, where the doctor will use a slit lamp microscope to check for corneal damage. Ear drops and eye drops are sometimes packaged similarly and may be misused by patients. Once the ear drops are mistakenly put into the eyes, the strong irritation of the drops may cause damage to the corneal epithelium, resulting in redness of the eyes, eye pain, photophobia, tearing and other symptoms. Patients need to immediately flush their eyes with water to rinse out the ear drops that have been mistakenly put into the eyes. Afterwards, the eyes should not be rubbed. Please go to the ophthalmology department of the hospital as soon as possible, and be observed by the doctor after magnification using a slit lamp microscope to see if the cornea has been damaged. If the cornea is damaged, it is necessary to actively carry out standardized treatment under the guidance of the doctor, so as to avoid delaying the course of the disease and causing adverse consequences.
