In recent years, many people have undergone myopia surgery, hoping to take off their glasses after the surgery and not have to worry about wearing cosmetic lenses. But there are also people who are skeptical about myopia surgery, wondering if they should have myopia surgery? Do you no longer have to worry about myopia after myopia surgery?
The survey data shows that there are about 600 million people with myopia in my country at present, and the probability of myopia in the youth group is 53.6%. About 81% of high school students have myopia problems. It can be said that myopia has become a common but under-appreciated health problem. Every year, about 1-2% of the myopia population considers myopia correction surgery. But there are not many people who really understand myopia surgery. Today I will show you about myopia surgery.
Myopia correction surgery, what is the principle?
Myopia correction surgery mainly improves the degree of myopia by adjusting retinal imaging. In people with myopia, intraocular lens is implanted into the eye through surgery to adjust the state of myopia. It’s like putting a “glass” inside the eye through surgery to allow people to see clearly.
Another option is laser surgery. In people with myopia, the curvature of the cornea changes to a certain extent, resulting in the inability of light to image on the retina normally. Laser surgery is to remove part of the corneal tissue and change the curvature to correct vision.
Both methods can solve the patient’s current myopia problem and improve the current degree of myopia.
After myopia correction surgery, can it be done once and for all?
For many people with myopia, how the surgery is done is not very important. The question is whether they can get better results after the surgery. For example, if the vision improves after surgery, will it be possible once and for all, and myopia will never occur again?
The answer is that myopia correction surgery can only remove the current degree of myopia as a means of correcting vision. But it does not play a preventive role. In other words, even if you have surgery for nearsightedness, it may still happen again in the future.
For example, after surgery, if you still maintain incorrect eye habits, and often take some behaviors that hurt your eyes, and do not pay attention to eye hygiene, it is likely to induce myopia again. This kind of surgery can only control the degree of myopia and correct the current vision, but it cannot completely cure or prevent myopia.
Originally, the higher the degree of myopia, the higher the risk in the process of undergoing surgery, and the problem of poor adaptability and inability to bear the amount of myopia correction after the hand. This also means that there are certain risks in surgery, and not everyone can receive myopia surgery.
Appropriate age group for myopia surgery, pay attention to 3 things
In general, the age of If you are over 18 years old, and meet the degree of myopia between 75 degrees and 1200 degrees, and the degree of astigmatism is within 500 degrees, you can choose to undergo myopia correction surgery after a detailed evaluation in a regular hospital.
What needs to be reminded here is that not only the degree of myopia needs to be within the range, but also the increase of the degree of myopia should be satisfied, which is relatively stable. Stability here specifically refers to less than 50 degrees of myopia growth and less than 100 degrees of growth within 2 years. This shows that the degree is relatively stable and the growth is relatively slow. If the growth is relatively fast, even if surgery is performed, there may still be a higher risk of vision growth afterward. This is not an appropriate time.
It is important for people of the right age to be able to do 3 things well after undergoing myopia surgery.
First, protect your eyes after surgery. After the operation, it is necessary to strictly follow the doctor’s advice to take drug treatment, and avoid direct contact with the eyes, rubbing the eyes, or looking at electronic products for a long time after the operation, which may irritate the eyes after the operation and cause discomfort. symptom.
Secondly, to control the time of eye use to reduce irritation. Generally speaking, in the 2 weeks after the operation, it is necessary to avoid looking at electronic products for a long time, and enter a stable period about 3-6 months after the operation, but also control the use time of electronic products. Relax your eyes for a period of time after the product, otherwise it will increase the risk of poor vision.
Also, maintaining healthy eye habits for a long time is of great significance for preventing myopia from increasing again. For example, keep an appropriate distance when looking at electronic products, reduce contact with the light emitted by electronic screens before going to bed, and keep the surroundings brighter when playing with mobile phones to avoid direct light irritation to the eyes.
If you have myopia correction surgery, you may often experience dry eyes, poor night vision and other problems, and you may not even be able to see directly like a normal person. Very intense light, but these transitions can be improved with active care and scientific eye usage.
Myopia is a very common disease for Chinese people, but it is rarely paid attention to. The myopia correction surgery can better improve the degree of myopia, and get rid of the shackles of glasses if necessary. But what everyone needs to understand is that myopia correction surgery does not prevent myopia, and it is still necessary to maintain healthy eye habits after surgery.
