Is myopia operation safe? After reading this, you will understand

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.

medically speaking, myopia is a kind of ametropia. In the refractive system of human eyes, corneal refractive power accounts for 70%. Corneal refractive power, It depends on the corneal curvature (the bending radius of the corneal surface).

that is, as long as the corneal curvature radius is reduced, the corneal refractive power can be reduced, and the external imaging focus will move back and fall on the retina, so as to correct myopia. Laser changes the corneal curvature radius by “thinning” the cornea.

Where does the laser “hit” during myopia surgery?

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.

laser surgery for myopia has a short laser wavelength and weak tissue penetration, which 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.

how does the laser “drill an eye” during myopia 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 stars 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.

warm reminder: to do myopia laser surgery, we need to have strict preoperative screening conditions and precise surgical operation equipment, and have high requirements for doctors’ qualification and experience. Therefore, people who want to do myopia surgery must go to a professional and regular hospital, strictly make preoperative evaluation, and then consider whether they are suitable for surgery.
