The keratoplasty lens is also called a rigid corneal contact lens, so the material of these glasses is relatively hard, so when they are first worn, it is possible that a more pronounced foreign body sensation may occur. After wearing them for a period of time, this symptom may occur as a result of irritation caused by damage to the corneal epithelium. Therefore, once these symptoms appear, the first thing to do is to go to the hospital as soon as possible to have an examination and choose a treatment plan according to the different conditions. If the symptoms appear in the early stage of wearing, it is usually the adaptation period, as long as the wearing time can be properly controlled, it can slowly return to normal. If corneal damage occurs, first of all, contact lens wear should be suspended and corneal repair treatment should be given to promote corneal repair, and if local inflammation exists, anti-inflammatory symptomatic treatment should be used.
