First of all, myopia surgery is not ** surgery, it is myopia correction surgery. Nowadays, most myopia surgeries are laser surgery of choice.
Laser myopia surgery uses a computer-controlled laser beam to cut a suitable concave lens in the cornea, so that external light can accurately converge on the retina to achieve the purpose of correcting myopia.
Laser surgery cannot change the structural changes of the eye caused by myopia, especially the fundus changes, and cannot **myopia. After surgery, it is still necessary to pay attention to eye use, reduce near eye use, avoid eye fatigue, pay attention to vision conditions, and have regular check-ups.
Myopia surgery cannot be done "once and for all".
Myopia surgery is to "eliminate" your existing myopia, but it does not prevent you from developing new myopia.
How to understand?For example, you now have 500 degrees of myopia, and through myopia surgery, your 500 degree myopia is eliminated, and you say goodbye to myopia.
However, if you do not follow the doctor's instructions, play with your mobile phone frantically, indulge in electronic products, etc. during the recovery period, the original 500-degree myopia will progress to 600 degrees, which is equivalent to your 100-degree myopia re-appearing after surgery.
How to crack?The body of an adult is mature, and myopia generally does not deepen easily unless you actively destroy it yourself. Therefore, it is not after myopia surgery**, as the prescription that has been eliminated will not be regenerated. It's that your original power has deepened.
In the final analysis, whether myopia or not deepens is actually up to you. You can think about how long it has been since your myopia has deepenedAs an adult, the vast majority of people have a long-term stable degree of myopia.
About "myopia regression".
Many people are skeptical about this problem and are worried that after a period of myopia surgery, myopia will reappear, leading to another operation. There are two main types of myopia regression:
Category I. In fact, it is not called myopia regression.
This is because the patient's own power is not stable and the operation may increase after the operation, so the indication for surgery is that the refractive power is stable.
Category II. Regression of myopia in the true sense of the word.
This type is because refractive surgery uses a laser to cut the corneal tissue, but the corneal tissue will grow to a certain extent, so some drugs are needed to inhibit its growth and regression after surgery.
Fallbacks below 20% are generally normal.
Therefore, myopia is only corrected and not **, although the surgery gives us a chance to recover from the factory, but eye protection depends on the individual, and we must also use our eyes reasonably after surgery and take good care of our eyes, after all, our eyes are the windows of the soul.
If this fact is not acceptable, surgery is not recommended. Myopia surgery is not a necessary surgery and you need to weigh the pros and cons yourself.
If you are determined to undergo surgery, it is recommended to choose an experienced surgeon from a regular public tertiary hospital, which can greatly avoid the risk of surgery.
