Astigmatism of 350 degrees can significantly affect the patient’s vision, the patient can correct astigmatism through refractive surgery to improve vision, generally will not recur, but the specific prognosis is related to the patient’s condition. Astigmatism is a common disease in ophthalmology, belonging to a type of refractive error, most of which is caused by congenital developmental abnormalities, and some patients are caused by bad eye habits, such as long-term squinting to see things. 350 degrees of astigmatism is a high degree of astigmatism, which will have a more serious impact on vision, and the patient can be corrected by refractive surgery, which will not usually recur. There are many refractive surgeries, such as corneal laser surgery, posterior chamber IOL implantation for crystalline eyes, etc., which are not prone to astigmatism recurrence after surgery. However, if patients do not change their eye habits and continue to squint or rub their eyes frequently, astigmatism may recur. It is recommended that patients with obvious astigmatism symptoms should consult a doctor in time to evaluate their condition and follow the doctor’s instructions for treatment.
