What is myopia surgery?
Disease description:
I have had myopia for many years, and I cannot see clearly without wearing glasses in my daily life, which is very inconvenient. I heard that there is a surgical procedure for correcting myopia. Could you please tell me what exactly is involved in vision correction surgery for myopia?

Myopia surgery, also known as refractive surgery or laser vision correction, is a procedure that improves vision by reshaping the cornea of the eye, thereby reducing or eliminating the need for glasses or contact lenses.
Common types of myopia surgery include the following:
1. Laser corneal refractive surgery: This procedure uses laser technology to correct myopia by altering the curvature of the cornea. It can be further divided into laser-assisted in situ keratomileusis (LASIK) and surface ablation procedures. LASIK involves creating a corneal flap using either a mechanical blade or a femtosecond laser, while surface ablation involves removing the corneal epithelium and applying laser energy directly to the corneal stroma.
2. Phakic intraocular lens implantation: Patients with high myopia can choose to have an artificial intraocular lens implanted in the anterior or posterior chamber of the eye to correct their vision.
3. Posterior scleral reinforcement: For patients with pathological myopia, this procedure involves reinforcing the posterior sclera to stabilize the axial length of the eye, control ocular expansion, and prevent further progression of myopia.
