Abstract: at present, there are many kinds of myopia laser surgery, and the prices are different. Its principle is to cut the corneal stromal layer in various ways, which is equivalent to cutting an accurate myopia degree suitable for one’s own on the human cornea. Because the corneal stromal layer has no regeneration ability, this diopter can be maintained for a long time. To achieve the purpose of correcting myopia.
nowadays, some young people have gathered together to “take off their glasses” and mentioned the original intention of taking off their glasses. Some of them said that they were able to choose a good major in order to fill in their volunteers, some were prepared for conscription, and some even felt that wearing heavy glasses was inconvenient and affected the beauty of life. But many people are still on the sidelines about the operation. According to research, the reason why many people don’t choose myopia surgery is that on the one hand, they are worried about its safety, on the other hand, they are worried about rebound after surgery. The reason for such concern is that on the one hand, I don’t know much about myopia surgery, on the other hand, the publicity of myopia surgery is overwhelming, and I don’t know how to choose a regular hospital for surgery.
we objectively introduce the principle and safety of myopia surgery with an attitude of popular science, in order to popularize the relevant knowledge of myopia surgery for the general public, help the people who are willing to surgery to objectively analyze and calmly choose myopia surgery.
the principle of myopia surgery?
at present, there are many kinds of myopia laser surgery, and the prices are different. Its principle is to cut the corneal stromal layer through various ways, which is equivalent to cutting an accurate myopia degree suitable for oneself on the human cornea. Because the corneal stromal layer has no regeneration ability, it can maintain this diopter for a long time. To achieve the purpose of correcting myopia.
myopia surgery will rebound?
everyone’s eye conditions are different, and the level of vision recovery is also different. The human eye is a very complex system. Myopia laser surgery changes the refractive power of the cornea through laser, and turns myopia into a built-in glasses. Therefore, this operation can only help patients achieve the best corrected vision. Most people can achieve 1.0 or 1.2, and individual vision may exceed 1.5, which is related to everyone’s ocular physiological characteristics and visual potential. In principle, there is no rebound problem in myopia surgery. The so-called rebound is mainly divided into two situations:
. One is the visual acuity fluctuation in the process of postoperative corneal wound healing. This problem can disappear through continued medication and recovery. After myopia surgery, as long as you follow the doctor’s advice, take medication, recheck on time, and pay attention to eye hygiene, generally there will be no visual regression. Choosing different surgical methods, the time of postoperative recovery is also different. It is suggested that we choose the one with less damage to corneal tissue and simple intraoperative operation, the better the postoperative visual quality and the faster the recovery.
the second kind of rebound is the patient’s own problem. In principle, there is no problem with normal eye use after myopia laser surgery. But if you continue to use your eyes with high intensity after surgery, (people who use their eyes continuously and closely for a long time, play games all night, and often stay up late) do not pay attention to eye hygiene: rub your eyes with dirty hands at the beginning of the operation. If the dirty water from washing your face and hair does not enter your eyes, low myopia or eye infection may reappear. This has nothing to do with the operation. Although myopia laser surgery can solve your myopia, it can not prevent you from getting sick again Second myopia.
