Can astigmatism in nearsighted eyes be corrected with surgery?

In general, individuals with myopia and astigmatism can undergo surgical correction, however, those with existing eye diseases or unstable vision prescriptions are not advised to have surgery.

Myopia and astigmatism are both types of refractive errors. Myopia refers to a condition in which, when the eye is in a relaxed state, parallel light rays from distant objects focus in front of the retina. Astigmatism refers to inconsistent refractive power across different meridians of the eye, causing parallel light rays to fail to converge to a single focal point on the retina after refraction. Both conditions can be corrected through surgery under a doctor's guidance. If the degree of myopia or astigmatism has remained relatively stable over the past year, this indicates a stable refractive state, which is a favorable condition for considering surgery. Adult vision tends to be more stable, making individuals more suitable candidates for laser vision correction surgery. For patients with high myopia or high astigmatism, implantable contact lens surgery or other surgical methods may also be considered.

If you have eye diseases such as glaucoma, keratitis, or diabetic retinopathy, this may increase the risk of surgery or affect surgical outcomes. If you are still in a growth and development phase, or if your glasses prescription has fluctuated significantly recently, this may indicate that your vision has not yet stabilized, and surgery at this time may lead to suboptimal results.

To ensure the safety and effectiveness of the surgery, it is recommended that you consult thoroughly with a professional ophthalmologist and undergo comprehensive eye examinations before deciding on surgery, in order to determine whether you are a suitable candidate for surgical treatment of myopia and astigmatism.
