Patients with colds are not recommended to wear keratoconus even if they are not severe, which may cause inflammation of the patient’s ocular surface. Colds are usually caused by bacterial or viral infections, which can lead to a decrease in the patient’s immunity. Wearing keratoplasty lenses may cause bacteria or viruses to get on the lenses, which can easily cause eye infections. In addition, taking anti-cold medicines and cough suppressants can lead to a decrease in tear secretion, and wearing keratoconus lenses can cause discomfort such as dryness and foreign body sensation in the patient’s eyes. Therefore, even if a patient’s cold is not serious, it is not recommended to wear keratoplasty lenses. It is recommended that patients with colds consult a regular hospital in time to assess their condition, follow the doctor’s instructions for treatment, and stop wearing keratoplasty lenses for the time being.
