It is always important to go to the ophthalmologist for a detailed examination to see if there is a real foreign body in the eye or if it is just a foreign body sensation. If it is a foreign body in the conjunctival sac, it can be treated by dipping a sterile cotton swab out and then giving anti-inflammatory eye drops. If it is a corneal foreign body, a superficial corneal foreign body can be removed under a slit lamp and treated with a combination of anti-inflammatory drops and corneal epithelial repair drops, such as tobramycin drops and Bevosol drops. If the foreign body is deep in the cornea, it is treated in the operating room to prevent serious secondary conditions such as corneal perforation. In case of foreign body sensation, conjunctivitis is common. Slit lamp examination is performed and conjunctival congestion is seen, with a large number of follicles and papillae on the conjunctiva, which can be treated with anti-inflammatory eye drops, along with less spicy and stimulating food and more water. Therefore feeling a foreign body, the first thing to see whether it is really a foreign body or a foreign body feeling, to the ophthalmology for detailed examination.
