High corneal curvature in children with patients may be caused by congenital corneal developmental abnormalities and the influence of acquired adverse factors. 1. Congenital corneal developmental abnormality: conical cornea is a common clinical corneal congenital developmental abnormality, which is mainly manifested as limited conical corneal bulge, the corneal stroma layer of the bulge will be thinned accordingly, and the cornea loses its normal curvature, so that the child can have an increase in corneal curvature. 2. Acquired factors: If the patient usually uses his eyes too much and rubs his eyes too often, it may lead to the formation of astigmatism, and the child may have an abnormal change of corneal curvature and so on. It is recommended that patients with corneal curvature abnormality should consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions to choose the appropriate treatment.
