Chicken eye itself has the characteristic of easy recurrence, and the reasons for its recurrence include incomplete treatment and failure to avoid triggering factors. 1. Incomplete treatment: If the patient is not completely cured during the treatment period, the corns may still remain in the local area and will reappear with the growth of time. 2. Failure to avoid triggering factors: If triggering factors are not avoided during the treatment period or in the prognosis, the lesions are still subjected to prolonged extrusion, prolonged standing, walking, or mechanical stimulation such as wearing high-heeled shoes or shoes that are too tight and narrow, which may again lead to localized keratosis, and thus lead to recurrence of corns. There are many reasons for the recurrence of corns, so it is recommended that patients go to regular hospitals to clarify the causes and follow the doctor’s instructions for treatment.
