Can myopia surgery once and for all?Experts remind that doing this can avoid postoperative vision backwards

Every summer vacation is the peak period of myopia surgery. Many parents think that children can remove glasses after surgery and restore vision. In fact, on July 20th, Wang Hua, director of the Hunan Provincial People's Hospital Eye vision center, said in an interview with reporters today that myopia surgery is only a way to correct myopia. Essence

Although myopia correction surgery is safe after more than 20 years of clinical verification, most people have good visual quality effects after surgery, but they also vary from person to person. Some people may have a little side effects. For example, in the early stage of surgery, the local eyes may be dry, the visual quality at night is slightly poor, and the lights are shining or aperture to see the lights. Impact.

How to ensure the safety of myopia surgery? Wang Hua reminded two points:

First, pre -operation examination is the key.

Not all patients with myopia are suitable for surgery. It has some specific requirements: for example, the age of 18-45; the number of myopia in the past two years is relatively stable; during the pre -surgery, if there are contact lenses, ordinary soft and invisible The glasses need to be stopped for more than 1 week, and the hard contact lenses need to be stopped for more than 1 month, while the cornea shaping lens needs to be stopped for more than 3 months. In addition, the eye has no organic disease and no activity inflammation.

At the same time, whether you can do myopia surgery and what kind of surgical method is suitable, you need to pass the preoperative examination to judge. A comprehensive preoperative examination usually takes about 2 hours. After about 20 detailed and in -depth inspections, the core key data is required to Repeated comparison of different inspection equipment. To avoid surgery risks and achieve good postoperative visual effects, pre -operation examination is a very critical step. Only through strict preoperative examinations and good doctor -patient communication and choosing the most suitable way of surgery can we ensure the safety of the surgery.

Director Wang Hua was interviewing reporters.

The second is to develop good eye habits and protect eyes after surgery.

It is not a lifelong insurance for myopia surgery. If you still use your eyes for a long time, you may still be myopia again. For middle school students around 18 years old, although the effect of the best correction can be achieved after surgery, if you do not pay attention to protecting the eyes, the number of myopia may continue to increase. In addition, whether it is laser surgery or crystal implant surgery, patients must be used in strict accordance with the doctor's advice.

Wang Hua emphasized that it is necessary to strictly follow the doctor's eye drops and regular reviews on time. Regular reviews can be understood in a timely manner, and doctors can also deal with possible problems in a timely manner. Avoid rubbing the eyes after surgery. Specific exercise should be avoided within one week after surgery. Swimming within one month after surgery to prevent dirty water from entering the eyes and avoiding external force impact. At the same time, the eye time and intensity should be appropriately arranged after surgery so that the eyes can be fully rest.

At present several mainstream myopia surgery methods

1. All -femtosecond laser surgery

Full femtosecond surgery does not need to make corneal petals. It only needs to take out the microscopy of the flying laser cutting through a tiny incision of 2-4mm. The postoperative recovery is fast. The postoperative operation will not affect the severe exercise. It is suitable for soldiers, athletes, police and other confrontation. Strong occupation.

2. Semi -flying laser surgery

Under the premise that the corneal thickness is sufficient, it is suitable for myopia people with a myopia below 1,000 degrees and sculpture below 600 degrees. For special eye conditions such as large astigmatism, irregular astigmatism, three personalized guidance surgery methods: corneal terrain map, wave anterior aberration, and corneal terrain diagram converting abbreviation. "Eye customization", the visual quality after surgery is higher.

3. ICL crystal implantation

ICL crystal implantation surgery is a special crystal (equivalent to a microfilm) into a specific location in the eyes, suitable for patients with medium -high myopic and corneal or shape problems that are not suitable for corneal laser surgery. The main advantage is that the corneal is not cut, and the visual quality of high myopia is good and reversible.
