Can a 3-year-old child self-heal?

3-year-old children with mild astigmatism can generally heal, but if there is severe astigmatism, it is generally unable to heal.

Usually, 3-year-old children's eye development is not perfect, at this time the corneal shape is relatively irregular, and the corneal curvature is relatively uneven, so it will cause physiological astigmatism. As age increases, astigmatism can gradually heal. However, if there is a serious astigmatism, the corneal shape can be significantly changed at this time, and it has the characteristics of long-term stability, so it cannot heal itself. With the development of time, the degree may gradually increase. If necessary, excimer laser surgery can be carried out to delay the degree growth.
