Foreign objects often enter the eye in daily life and work. When a foreign body enters the eye, it often causes eye pain, tearing, foreign body sensation and other discomforts, and if the cornea is damaged, photophobia/blurred vision. This is what we usually call “no room for sand in the eye”. Into the eye of the foreign body: may be the wind fluttering sand, welding or cutting spattered metal shavings, firecrackers or explosions, spattered metal or gunpowder particles, like smoking is burning soot, nail gun shot and then rebound nails, factories or laboratories used in acid, alkali and other corrosive liquids, haircuts, hair of animals, shoveled off the wall when working, spilled iron, pesticides or cinders, farming, etc, Pesticides or cinders, chestnut thorns, wheat mango (mang), chaff, etc., which are often seen during the farming season, may become a foreign body into the eye. The following chart: So, what should we do when something gets into the eye? Because of the location and severity of the corneal foreign body, the treatment method is different. For example: 1, foreign body attached to the surface of the eye can be gently swabbed away with a cotton swab dipped in saline or eye drops under surface anesthesia; or flushed with saline to make the foreign body flow out with water. 2.Foreign bodies located in the superficial or deep layers of the cornea or when the foreign body penetrates the cornea and partially enters the anterior chamber: then a professional is required to remove the foreign body with a foreign body needle or fine needle under a slit lamp microscope. Note: Although foreign bodies entering the eye are different, they all may cause major or minor damage to the cornea. If they are not handled in time or improperly, they may cause keratitis, and in serious cases, they may even form serious complications such as corneal ulcer, corneal perforation, endophthalmitis or even blindness. Therefore, once a corneal foreign body occurs, it must be removed as soon as possible, and then, the corresponding anti-inflammatory and symptomatic treatment should be given. In addition, in our daily life and work, we should actively take protective measures to prevent or reduce the occurrence of corneal foreign bodies as much as possible.
