A break in the outermost layer of the eye is usually a sign of damage to the conjunctiva or cornea, which are two different conditions and treated differently. In the case of conjunctival damage, generally if it is a relatively intact conjunctival wound and is not very long or small in extent, it can be treated without treatment. Because the conjunctiva has a very strong healing ability, it can return to normal on its own within 24 hours. However, if the conjunctiva is very severely damaged, or if it is very long and extensive, then debridement and suturing surgery should be performed to restore the integrity of the conjunctiva. If the cornea is damaged, this is more serious, because the cornea is part of the refractive media, and if it is not treated in time, once a local infection is formed, it can lead to vision loss. Therefore, in this case, it is important to improve the examination early, and the integrity of the cornea can be restored by medication and surgery.
