Is myopia operation safe?

Abstract: laser surgery for myopia belongs to the operation of eye surface, which only carries out fine cutting on the anterior surface of cornea. The cornea of human eyes is divided into five layers. We operated on the first third of the cornea. And the cornea is the most anterior tissue of the eyeball. During the whole operation, the eyeball is still closed. First, I want to say that

is increasing incidence rate of myopia with the application of various screen terminal monitors. However, many myopia patients have not been corrected, and some of them are worried about the safety of myopia laser surgery and eye damage.

and

in fact, laser surgery for myopia has been carried out for nearly 30 years. It is not a “new technology” in everyone’s mouth. With the improvement of equipment and technology, the safety of surgery is more and more guaranteed. In particular, femtosecond assisted LASIK and all femtosecond laser surgery are quickly accepted by doctors and patients because of their high safety. Under the current medical level, doctors can carry out personalized surgical design for patients, so that each patient can obtain more accurate, safer and reasonable treatment effect and better postoperative visual quality. I mainly elaborate its safety from two aspects:

and

. First, where does the laser hit during operation?

myopia laser surgery belongs to the operation of eye surface. The operation is only fine cutting on the anterior surface of cornea. The cornea of human eyes is divided into five layers. We operated on the first third of the cornea. And the cornea is the most anterior tissue of the eyeball. During the whole operation, the eyeball is still closed. The laser wavelength used in myopia laser surgery is very short, the tissue penetration is very weak, and will not damage other tissues in the eye. In other words, laser surgery will not have any adverse side effects on the internal tissues of the eyeball, nor will there be appalling phenomena such as “myopia and blindness”, nor will there be sequelae after several years of treatment.

second: how does the laser “drill holes” during surgery?

myopia laser surgery is a highly automated surgery. Doctors strictly operate the computer, digitize the whole process, and have a high degree of safety and accuracy. The laser in the process of myopia surgery has an infrared tracking system. During the operation, if your eye deflection exceeds the normal range, the laser will automatically stop shooting, so as to ensure the safety of the operation and avoid “Deviation”. Therefore, some external eye diseases such as “glaucoma and cataract” have nothing to do with “eye deviation” of myopia. Myopia surgery will not increase or reduce the incidence of other eye diseases.

in fact, there is no place in the developed countries (or regions) in the world that prohibits myopia laser surgery. Many of our favorite “little fresh meat” and “handsome uncle” have also undergone myopia laser surgery. Many people say that ophthalmologists do not do laser surgery for myopia. In fact, that is a misunderstanding. Inside the hospital, many doctors, medical staff and their families do myopia laser surgery every year. Because medical staff understand the process of myopia laser surgery, they believe it is safe.
