Hello, there are many kinds of laser surgery methods for myopia at present, but they are not suitable for all myopia people. Before the operation, strict examination is needed. An experienced refractive doctor will help you analyze whether you can accept the operation and what kind of operation to take according to your examination results and the overall situation of your eyes to ensure the safety of the operation. Laser surgery for myopia is to flatten the anterior surface of cornea by laser cutting, so as to correct myopia. After the precise setting, the laser only acts on the cornea and cannot enter the eye, and the operation will not interfere with other tissues of the eye. Most patients can take off their heavy glasses at one time, and the naked eye vision after operation can generally reach the best corrected vision of preoperative glasses. If you have any plans for surgery, I suggest that you can first find a professional eye hospital to do relevant examinations to determine whether you are suitable for surgery.
