Removal the foreign matters of corneal
Foreign bodies in the eyes are a common problem. It may be feathers, sand grains, stone or metal particles. An uncomfortable condition typically arises due to non-compliance with the protection steps. Most people lack goggles while they deal with wood, plastic, iron, steel.
Corneal external bodies cause pain, cause extreme annoyance, and cause visual disability. The fragments stay on the surface, or penetrate to the bottom, depending on the size and structure. It is not recommended that you extract them yourself; it is best to get a doctor's aid. Particles can penetrate the eye if removed incorrectly, and damage its structure.
Points of order
It is a very complicated operation to extract a foreign cornea bone. It is important to assess the type of occurrence and the extent of penetration of a foreign body before executing. Biomicroscopy is performed for this reason. Biomicroscopy is performed for this.
Extraction of the outer body is performed under local anesthesia. Anesthetic products are used for anaesthesia. When the particles are on the cornea surface they are extracted with a moistened cotton swab. Special ophthalmic devices are used to remove deeply embedded objects: disposable needles,. It is advised to instill antiseptic drops during the recovery phase and, where possible, to use antibacterial ointments to avoid infection and inflammation
Foreign bodies deep inside the cornea are not usually to be extracted because they are chemically inert and do not cause inflammation. This is achieved with the smallest particles of rock, stone, sand, glass, gunpowder, etc. that have entered the deep layers of the cornea's own material and remain in it without a noticeable eye-side reaction.
In the presence of several particles in the cornea at different depths, to prevent unnecessary damage to the corneal tissue, foreign surface bodies are typically removed primarily, particularly those that annoy the victim. Over time, deeply placed bits of easily oxidized metals (copper, brass, etc.) often migrate spontaneously to the surface layers of the cornea and have to be removed with eye irritation signs.
Leaving iron-containing particles in the cornea is undesirable, because a region of staining of their own material is created very rapidly around them in a rusty colour. Deeply lying corneal foreign bodies are subject to removal if they are followed by inflammatory processes of their own material, are chemically active, and can often partially protrude above the anterior epithelium or penetrate the anterior cavity.
