Astigmatism can be treated with laser surgery. Most astigmatism is congenital, but it can also develop later in life due to poor eye habits. As long as the astigmatism is small enough that it does not affect your vision, it does not need to be corrected. High astigmatism has a significant effect on vision and can be corrected with laser surgery. If nearsightedness and farsightedness are present, laser treatment can be done together without correcting the astigmatism separately. Astigmatism symptoms can be corrected with laser surgery, and commonly used procedures include excimer laser and femtosecond laser. These two means, can cut the stroma layer of the cornea, change the radius of curvature of the cornea, and thus can achieve the purpose of correcting astigmatism. Each patient’s condition is different, and you can consult a medical professional for advice on whether or not you can undergo laser surgery.
