The average curvature of the human eye is about 43D, and keratoplasty lenses can usually flatten the curvature to about 36D. When the curvature of a child is 41.9D, the flattening curvature is reduced accordingly, but keratoplasty lenses can be worn if other conditions are met.
Keratoplasty is a kind of rigid corneal contact lens, its principle is to wear at night to flatten a certain corneal curvature to change the refractive state of the cornea so that the next day’s vision to reach the normal level, in addition to the correction of myopia, but also to play a role in alleviating the growth of myopia, and it is more suitable for adolescent patients.
If the child has keratitis and other eye surface inflammation, not suitable for wearing keratoplasty lenses, the child can wear frame lenses to correct myopia, thereby improving vision.
Myopia patients are advised to consult a doctor in time to assess their condition and follow the doctor’s advice to choose the appropriate treatment.
