Summary

This subject is mainly to study difference of Congenital cataract preoperative related parameters in children with or without Microcornea within Less than one year old. A total of 186 eyes of 117 people were collected with relevant ocular biological parameters, including age, horizontal diameter of the cornea, Eye axis, intraocular pressure, steep axis of corneal curvature, flat axis of corneal curvature, corneal thickness, lens thickness, anterior chamber depth. At present, because the definition of patients with small cornea is not clear enough, the study subjects are divided into 4 groups according to the horizontal corneal diameter of 9.0mm, 9.5mm, and 10.0mm, namely ≤9.0mm group, 9\~9.5mm group, 9.5\~10.0mm group and The \>10.0mm group compares the differences between each other, and tries to provide a reference for the diagnosis of children with small cornea at a young age.
