Keratomileusis generally refers to rigid gas permeable contact lenses for keratomileusis, which are generally not recommended for tonsillitis. Keratoplasty rigid gas permeable contact lenses are rigid gas permeable contact lenses that use keratoplasty to change the shape of the cornea to temporarily correct refractive errors. They are mainly used for patients who require correction of myopia, astigmatism or prevention of myopia progression and do not wear eyeglasses. When the patient has tonsillitis, the body’s immunity is low and resistance to external bacteria and viruses is weakened. Lens itself, poor fit, removal operation or improper lens care can increase the probability of corneal infection, so patients with tonsillitis are not recommended to wear rigid gas permeable contact lenses for keratoplasty. Therefore, patients with tonsillitis are not recommended to wear rigid gas permeable contact lenses for keratomileusis. It is recommended that the patient go to the hospital in time and wear rigid gas permeable contact lenses for keratomileusis after the tonsillitis has been treated.
