How does child astigmatism return a responsibility?

summary

In daily life, astigmatism is a state of ametropia. Ask patients to keep enough attention to accept the treatment of this disease, due to the complex symptoms of astigmatism, the cause of astigmatism is also very complex, that in order to make you better able to correct astigmatism, so we must do a good job of this disease related work, so how about children astigmatism?.

How does child astigmatism return a responsibility?

First: curvature astigmatism: caused by abnormal changes in corneal curvature. If the meridian with the largest refractive power and the meridian with the smallest refractive power are perpendicular to each other, regular astigmatism is caused, which is mostly congenital, and the degree of astigmatism is large. If the surface of the cornea is irregular deformation, uneven bending, unable to form a focus on the retina, it is called irregular astigmatism, such as corneal traumatic scar, keratoconus, corneal degeneration and so on.

Second: refractive rate astigmatism: it is caused by the change of refractive index of lens. Astigmatism degree is generally small, such as senile cataract, lens cortex water gap, feathery opacity, resulting in changes in the refractive index of the lens, can form astigmatism.

Third: eccentric astigmatism: previously seen in crystal displacement, such as congenital deviation, crystal subluxation, etc.

matters needing attention

Therefore, don't let astigmatism accompany your child for a lifetime. Having a bright and fresh future is the best gift for your child!
