What are the pros and cons of myopia surgery?

Myopia affects many people. Surgical treatment of myopia can be said to be a relatively effective method. In this way, you don’t need to wear glasses in the future. However, there may be certain risks or sequelae after myopia surgery.

1. Myopia causes us a lot of inconvenience in life. Most of myopia is caused by not being able to use the eyes well and healthily, and some of it is caused by genetic or environmental problems. Acquired myopia can be treated through myopia surgery. If the patient is not careful after the operation or the medical institution he chooses is not professional enough, it is easy to cause sequelae. A detailed examination before surgery is one of the necessary procedures to prevent sequelae.

2. The safety of laser correction surgery is related to the doctor's operating experience and equipment. Surgery is not risk-free, and the main thing to do is to avoid two postoperative complications. Any corneal surgery that leaves a wound presents a chance of infection. Some of the sequelae of myopia surgery are caused by the wound being exposed to the air after the cornea recovers. If you do not pay attention to hygiene, it will cause inflammation and infection.

3. The treatment of myopia is to make the cornea flatter, but a cornea that is too flat will be squeezed by the pressure from inside the eye, causing the cornea to bulge forward. People cannot feel this pressure, but the consequence is that not only will it fail to cure myopia, but it will aggravate it and even cause irreversible astigmatism.

4. The occurrence of sequelae of myopia surgery is sometimes caused by the hospital’s failure to carefully screen and exclude patients with congenital eye diseases before the operation.

5. Even though qualified patients are screened, doctors may not perform the surgery on the right scale during the operation. For example, a certain corneal thickness should be maintained, but some doctors want to completely correct the vision of patients with high myopia and cut the cornea too thin, leading to adverse consequences.
