Do you believe that you can treat myopia permanently without surgery?
As an important organ for the human body to perceive the outside world, the importance of the eye is beyond doubt. Today, the birth of many electronic products, as well as people's long-term lack of sufficient sunlight, has led to a growing population of myopia. Many people have therefore considered surgery to correct their myopia. Although the development of myopia surgery has been around for a while, the risks involved are still prohibitive for many people.
Principle of visual formation
Today, a new technology is quietly evolving. Recently, the international top journal Nature Photonics published a message in which Columbia University scientists Sinisa Vukelic and Chao Wang proposed a photochemical-based approach that can be corrected without surgery. Vision of myopia patients.
The reason why we can see the object is because the light reflected by the object passes through the cornea, pupil, and then through the lens, through the vitreous, and then concentrated on our retina, and finally through the brain, and finally formed our vision.
There are two reasons for the production of myopia. One is that the cornea is no longer flat and becomes steep. Therefore, the light reflected by the object overlaps before reaching the retina. The projection on the retina is scattered, so the blurred vision is seen. Unclear. The other is that the eye axis of the eyeball becomes larger, which is equivalent to pushing the projector far from the vicinity, and the image projected on the retina is thus blurred. So some people invented the glasses, through the role of the lens to let the light accurately collected on the retina. But some people want to be able to do it once or for all, or simply don't like to wear glasses, so surgery has become another option for these people.
Method of treating myopia
Currently, the most commonly used treatment for myopia is refractive surgery. It can quickly and effectively restore patients to their own myopia, but because this surgery is an invasive surgery, there are still some factors of instability, in some cases patients experienced permanent blindness after surgery.
In addition, laser surgery, such as excimer laser in situ keratomileusis (LASIK) and excimer keratectomy (PRK), laser ablation of the cornea to achieve a thinner cornea, thereby improving the patient's Myopia, but such surgery can make the cornea more fragile.
If the patient's cornea itself is very thin, or if there are other factors such as dry eye, then the above methods are not suitable. So at this time, the method of myopia correction without surgery will become the gospel of these people. Instead of cutting off the excess cornea, or laserizing the cornea, use a femtosecond shaker to change the structure of the cornea.
