How is refractive surgery for correcting myopia performed?
Disease description:
I have had myopia for many years, and the degree of myopia has been increasing. I cannot see clearly without wearing glasses in daily life, which is very inconvenient. I would like to learn more about how vision correction surgery for myopia works. I heard there are different types of surgical procedures; which one would be more suitable for me?

Myopia correction surgery mainly aims to improve vision by altering the curvature of the cornea or lens.
1. Corneal refractive surgery:
Principle: Using excimer or femtosecond laser to perform precise cutting on the corneal stroma.
Indications: Generally suitable for patients with myopia up to 1200 degrees.
Procedure: Includes preoperative eye irrigation, anesthesia, creation of a corneal flap, and laser ablation.
2. Intraocular refractive surgery:
Principle: Correcting myopia by implanting an artificial intraocular lens with the appropriate refractive power to alter the eye's focusing ability.
Indications: Suitable for patients with high myopia or thin corneas.
Techniques: Includes phakic intraocular lens implantation or lens replacement surgery.
3. Postoperative care: After surgery, antibiotic and corticosteroid eye drops are required to prevent infection and control inflammatory responses.
Myopia correction surgery is not suitable for everyone. Prior to surgery, strict preoperative evaluations must be conducted to identify contraindications and ensure the safety and effectiveness of the procedure. It is recommended to visit a正规 hospital and undergo the procedure under the guidance of qualified physicians.
