Is it serious for children to have astigmatism of 200 degrees?

Parallel rays of light from the outside world are refracted by the refractive system of the eyeball, and cannot form a clear focus on the retina, but a blurred focal line, and this refractive state is called astigmatism. The cause of astigmatism is due to the difference in the refractive index of the two plant lines of the eyeball. Generally speaking, if the astigmatism is below 150 degrees, if there are 200 degrees of astigmatism, it must be beyond the range of physiological astigmatism, which is not normal. So after the child is born, there is actually a certain physiological astigmatism.

What are the dangers of astigmatism surgery?

The hazards of astigmatism surgery are also the hazards of myopia laser surgery, mainly including:

First, the corneal tissue becomes thinner after surgery, the firmness of the eyeball decreases, and the risk of eyeball rupture after trauma increases.

Second, there is a high chance of dry eye syndrome after surgery because part of the corneal tissue is cut, but it is possible that the symptoms will gradually resolve over time.

Thirdly, myopia recurrence and glare are are likely to occur after surgery, especially in a dim environment, the pupils are enlarged, and glare will seriously affect the quality of vision. Fourth, patients with high myopia have a slightly greater risk of retinal detachment and macular edema after surgery.

How astigmatism is caused in young children's eyes

It may be because eye surgery, such as cataract surgery or eye trauma surgery, or removal of corneal dermoid tumors, can also cause some degree of astigmatism. There are also some astigmatism, which may be caused by corneal leukoplakia and corneal patches left by eye trauma or eye burns.

In some children, astigmatism may be caused by congenital eye lesions, such as keratoconus, or congenital corneal leukoplakia, congenital spherical lens, etc. Generally speaking, after birth, most babies may have some physiological astigmatism, with a degree below 150 degrees.
