Can laser surgery be performed for astigmatism?
My astigmatism is over 400 degrees, and I usually experience double vision and blurred vision. When driving at night, streetlights appear to me as scattered light. Can laser surgery improve this condition?

In general, laser surgery can be performed to correct astigmatism, but the decision depends on a thorough evaluation of the patient's specific condition.
The principle of laser surgery for correcting astigmatism involves precisely reshaping the corneal surface with a laser, thereby adjusting the focal point of light entering the eye and achieving improved vision. Prior to surgery, comprehensive eye examinations are conducted to assess factors such as corneal thickness and the degree of astigmatism in order to determine the most suitable surgical plan.
Typically, astigmatism up to 600 degrees can be considered for laser surgery, and the results are generally favorable. However, if the degree of astigmatism is too high or the patient has other eye conditions such as a thin cornea or keratitis, laser surgery may not be appropriate. Therefore, it is important to have a thorough discussion with a qualified ophthalmologist and undergo a comprehensive evaluation before deciding on surgery to ensure optimal results and safety.
On the day of surgery, patients should wash their face thoroughly, avoid wearing eye makeup, and refrain from using perfumes or other irritants. Additionally, proper rest and postoperative care should be arranged to maintain the surgical outcome.
