Astigmatism after myopia surgery

Because many people nowadays do not use their eyes correctly and spend long periods of time immersed in electronic products, their personal vision is easily affected. However, myopia is only a relatively simple case. Currently, a considerable number of people still have astigmatism problems. Astigmatism is mainly caused by the curvature of the retina, which causes the light reflected from objects into the eye to be deflected and unable to focus, resulting in the problem of astigmatism.

We often hear that many people are nearsighted or farsighted, but what should we do when our eyes have astigmatism? Should we just leave it alone? Today I will tell you how we should treat astigmatism. Never leave it alone, as it will be the same as myopia. It will increase very quickly in the later stage and it will harm yourself.

1. How can I confirm whether I have astigmatism?

There are double images when looking at things or lights. For example, when looking at the numbers on the blackboard during class, there will be double images when looking at 1, resulting in seeing 11. When looking at classmates far away, there will be a blurry shadow above their heads. Eyes with astigmatism are actually more prone to fatigue, making people feel that using their eyes is very "laborious", and often delaying things. Therefore, when astigmatism is detected, it must be corrected in time!

2. What are the methods for correcting astigmatism?

➤Myopia surgery

Some people have simple astigmatism, while others have astigmatism and myopia. If you are an adult over the age of 18, you can consider correcting it through myopia surgery. The scientific name of myopia surgery is refractive surgery, which can not only correct myopia, but also correct astigmatism. Correct myopia and astigmatism at one time through surgery.

➤Contact lenses

Ordinary frame glasses cannot correct irregular astigmatism, and the correction effect on high astigmatism is not satisfactory. For this, hard corneal contact lenses, namely RGP lenses, are used for correction. The advantages of wearing RGP lenses are: compared with frame glasses, RGP lenses are worn directly on the cornea, forming a "tear lens" between the lens and the cornea, which can better correct irregular astigmatism; high-power frame glasses are very thick, and when you look at things through the lenses, the magnification or reduction ratio is very high. Wearing RGP lenses on the cornea can greatly reduce the aberration caused by thick lenses, reduce the degree of distortion when looking at things, and improve the image quality; RGP lenses also have a certain shaping effect on the cornea, making the cornea more regular, and the degree of astigmatism in some people will be reduced.

➤Frame glasses

Suitable for regular astigmatism and lower degree astigmatism. Before wearing glasses, children need to undergo retinoscopy and eye examination by an optometrist. If necessary, children can undergo mydriasis refraction (under the guidance of a doctor). After understanding the nature and degree of astigmatism, they can wear and try on the glasses and finally get fitted with astigmatism glasses that suit them.

If you find that you or your children have myopia or astigmatism, you must go to a regular ophthalmology hospital for a consultation and eye test as soon as possible. If it is confirmed that you are myopic, you must get glasses or orthokeratology lenses in time. Don't think that wearing glasses will increase the degree of myopia. This is a misunderstanding. Only by insisting on wearing glasses can you control the degree of myopia.
