"There are myopia and astigmatism. Can the astigmatism be corrected during myopia surgery?" "My myopia degree is not high. What should I do if the astigmatism number of is relatively high? Can I have surgery?" Faced with the mirror removal, myopia often raises these questions. Today, let's follow Xiao Pumei to learn about it!
1 What is myopia + astigmatism?
Simple says that the world of astigmatism is blurred and ghosted.
The higher the astigmatism, the more the degree of blurred ghosting may be. After parallel light enters the eyes, the normal eye is the light that is accurately focused on the retina, while myopia is the focus point before the retina, while astigmatism means that the light cannot accurately concentrate on the same focus.
If you have both myopia and astigmatism, in addition to decreasing vision and heavy shadows in watching things, you will also be prone to symptoms such as vision fatigue, even eye pain and headache, and work at close range cannot last long.
2 Can laser surgery correct myopia and astigmatism at the same time
Myopia surgery . Some friends may think that they can only correct myopia, but in fact they are more than just.
Myopia surgery is equivalent to wearing glasses into the eyes. Myopia and astigmatism that can be corrected by glasses. Myopia surgery is generally applicable.
Myopia surgery is a refractive surgery, while refractive error includes myopia, astigmatism and hyperopia . Therefore, myopia surgery can not only correct myopia, but also correct astigmatism.
3 How many degrees of astigmatism can be corrected by myopia surgery
Different astigmatisms can be corrected by myopia surgery. Generally speaking, myopia surgery can correct astigmatisms below 600 degrees, and there are also a few special groups that can exceed this degree.
However, if the corneal thickness is not ideal, not everyone can correct this degree. Moreover, which correction method is chosen must be determined through professional preoperative examinations. The doctor will give a method suitable for the patient through the examination results.
Milor astigmatism (within 50 degrees) generally does not require correction. Generally speaking, the astigmatism number is relatively stable and will not change much in a short period of time. As we age, the astigmatism number or the astigmatism axis may change slightly.
