Do I need to wear glasses for astigmatism 100 degrees Can astigmatism be corrected
As we all know, the main causes of astigmatism are curvature astigmatism and exponential astigmatism, and corneal diseases, corneal degeneration, cataracts and corneal surgery can also cause astigmatism. At present, there are many people with astigmatism, so do I need to wear glasses for astigmatism of 100 degrees? Let's find out!

Do I need glasses for astigmatism 100 degrees?
100-degree astigmatism is mild astigmatism, which usually does not have much impact on vision, and you don't need to wear glasses, but if you don't feel clear or have high requirements for visual quality, you can also wear glasses and it won't hurt your eyes. If you don't want to wear glasses, you can also consider laser surgery.
Can astigmatism be corrected?
Astigmatism is a type of refractive error, which can be corrected, and there are generally three ways to correct it.
1. Eyeglasses are the most commonly used method. Generally, for mild or moderate astigmatism, you can choose a way to correct it, and the effect is very ideal.
2. Corneal contact lenses, also known as contact lenses. For a high degree of astigmatism, a method can be chosen to correct it.
3. Refractive surgery, such as excimer laser surgery, femtosecond laser surgery, etc. Surgery is generally used to correct astigmatism in adults, and surgery can only be considered if you are at least 18 years of age.
Can astigmatism plus myopia be treated with femtosecond laser surgery?
ReLEx laser surgery uses a femtosecond laser to perform two scans between the corneal layers to form a lens, which is removed through a micro-incision, so as to achieve the purpose of correcting myopia and astigmatism.
Femtosecond laser surgery first uses femtosecond laser to make corneal flaps, and then uses excimer laser to cut the corneal stromal layer to change the radius of curvature of the cornea, which can achieve the purpose of correcting myopia and astigmatism.
However, this surgery requires patients, first of all, the patient must be at least 18 years old, and the diopter power is stable, and the simple astigmatism power cannot exceed 600 degrees. If astigmatism and myopia are too high, there is a risk that the cornea is not as thick as it needs to be corrected by femtosecond laser surgery. If the corneal thickness does not meet the requirements, on the one hand, it will cause postoperative undercorrection, and on the other hand, it may cause complications such as secondary conus, so not all myopic astigmatism patients can be corrected by femtosecond laser surgery.
How is astigmatism caused?
1. Heredity: heredity is the main factor of astigmatism, according to clinical data statistics, the probability of astigmatism in minors with astigmatism in either parent is much higher than the probability of astigmatism in minors with both parents.
2. Bad habits: Maintaining bad eye habits for a long time, such as lying down and reading, often rubbing and squinting, is easy to compress the cornea, which changes the shape of the cornea, and then leads to astigmatism.
3. Diseases: Astigmatism can also occur after curing of some eye diseases, such as keratoconus, corneal ulcer, keratitis, pterygium, etc.
4. Trauma and surgery: When corneal damage occurs and some eye surgery errors occur, keratoconus may be caused, and astigmatism may occur.
5. Advanced age: The probability of astigmatism increases significantly with age, which may be related to the natural aging of the human body, and is generally more common in the elderly over 65 years old.
6. Malnutrition: When the human body is malnourished, the hardness of the cornea will decrease significantly, and the risk of corneal astigmatism will increase.
7. Obesity: According to relevant research statistics, among patients with clinical astigmatism, there are significantly more obese minors than normal minors. Therefore, not all patients with myopic astigmatism can be corrected by femtosecond laser surgery.
