What are the advantages and disadvantages of myopia laser surgery? How big is the risk?
Advantages and disadvantages of laser surgery for myopia are as follows:

Advantages: Patients can get better corrected vision after myopia laser surgery, and can see things in the distance clearly. At the same time, some patients choose this operation because of special needs, such as wanting to join the army and do some special jobs, including flight attendants and surveyors. The benefits that patients can get from this operation are that they can get good eyesight and be able to engage in these related jobs;

2. Disadvantages: This operation will cut human corneal tissue and cause certain damage to the tissue. Although there are no blood vessels in the cornea, there are many nerve tissues such as nerve endings, which will bring adverse effects after being cut off. For example, after surgery, you will feel eye pain and dry eye, especially for patients with dry eye before surgery. This kind of laser surgery will also reduce the vision of some patients at night. If some patients drive at night, they will also find a circle of aperture in front, that is, night glare, which will affect patients' travel at night and affect visual quality.
