Can astigmatism do myopia surgery

Abstract: astigmatism is a kind of ametropia. Human eyes are not perfect. The cornea of some people is curved at a certain angle, while others are flat. These uneven thickness or curvature of the cornea make the light entering the eye unable to focus accurately on the retina, which is called astigmatism.

for a long time, many myopia friends have formed a fixed impression. The operation of using excimer laser to solve ametropia is called myopia operation. In fact, myopia operation can not only correct myopia, but also correct a certain degree of astigmatism and hyperopia. Myopia is only one kind of ametropia. It also includes hyperopia and astigmatism.

what is astigmatism

The best way to correct astigmatism is to choose femtosecond laser myopia surgery guided by corneal topography. Generally speaking, astigmatism within 600 degrees can achieve ideal correction results.

astigmatism friends need to go to the hospital for a comprehensive preoperative examination before myopia surgery. If it is confirmed that it meets the myopia operation conditions, it can not only effectively correct myopia, but also effectively correct astigmatism.
