Can laser surgery correct astigmatism?

Laser surgery can generally correct astigmatism, but specific criteria must be met and a professional evaluation is required. The details are as follows:

Laser surgery can treat astigmatism by reshaping the anterior corneal surface and adjusting corneal refractive power, enabling light to focus precisely on the retina, thereby correcting astigmatism. However, certain conditions must be satisfied: for example, astigmatism should have remained stable for over two years, corneal thickness and curvature must meet surgical standards, and there should be no ocular diseases such as dry eye or glaucoma. Only after a comprehensive ophthalmic examination and professional assessment can it be determined whether a patient is suitable for surgery.

For the first week after surgery, avoid getting water in the eyes and do not rub them to prevent corneal infection or poor healing. Wear protective sunglasses when outdoors to reduce irritation from wind, dust, and bright light. Limit screen time; during the initial recovery period, avoid prolonged screen use and take breaks every 30 minutes by focusing on distant objects. Use prescribed antibiotic and artificial tear eye drops as directed, attend regular follow-up appointments to monitor vision, and seek medical attention promptly if symptoms such as blurred vision or eye pain occur.
