Corneal opacification is usually defined as a loss of corneal clarity due to various causes, and treatment of this condition depends on the stage of the disease. If the condition is in the active phase of the disease, such as active inflammation, anti-inflammatory treatment is needed to control the inflammation to normal and restore the corneal clarity. If the disease is in the stable phase, such as corneal scarring due to trauma or inflammation of the cornea, in this case, it depends on the magnitude of the impact on vision to determine if treatment is needed. If the corneal clouding is marginal and does not affect vision, it may not need to be treated, but if it is in the central area of vision, it may cause a significant loss of vision and a corneal transplant may be performed to improve vision. Therefore, the presence of corneal clouding should be examined in detail at the hospital before the appropriate treatment.
