At the two sessions of the National People's Congress in 2022, some representatives suggested that myopia people aged 18 to 45 should undergo surgical correction.

Questions were raised:
"Many ophthalmologists also wear glasses, they don't do myopia surgery themselves, why let others do it?" Isn't it unsafe? ”
Regarding the answer to this question, we listen to what Tao Yong, the "eye professor without glasses", said...

Maybe it was surgery, but you didn't see it?
Some ophthalmologists do not have myopia surgery, not because they do not believe in the operation, but because they do not have this need.
Because not doing surgery does not affect him to see people.
Most of the ophthalmic treatment is done under microscopic conditions, requiring the help of a surgical microscope, and there are not too many requirements for naked eye vision.
Therefore, whether to do or not to do myopia surgery is a personal choice of the doctor.
After all, an ophthalmologist who can treat people's eye diseases is the best ophthalmologist!
The term "sequelae" sounds frightening. Especially moving a knife on the delicate eyes, it is inevitable that people will be weak-hearted.
But don't be afraid, regarding the discomfort after myopia surgery, the most clinically observed at present is dry eye syndrome and vision regression.
1. Dry eye
During surgery, it may damage the nerves of the eye and corneal epithelial cells, disrupt the regulation function of the eye, and affect the secretion of tear fluid.
Without the moisture of tear fluid, the eyes will dry out [1].
However, as the cornea heals itself, the symptoms of dry eye also disappear [2].
2. Vision regression (deepening of myopia)
Most of them are due to poor eye habits after surgery, and the heavy burden on the eyes, resulting in deeper myopia.
Generally speaking, after the degree of myopia in adults tends to be stable, as long as they are strictly examined before surgery, follow the doctor's instructions, use their eyes reasonably, and review regularly after surgery, there will be basically no regression in vision.
However, for patients with high myopia (above 600 degrees), due to the elongation of the eye axis, there are many fundus lesions, and although the vision is improved after surgery, these fundus lesions still exist. If you don't change your eye habits and don't take care of your eyes, you may really be myopic again [3].
If you want to correct it after "re-myopia", the difficulty and sequelae problems will be greatly improved.
Therefore, after surgery, we must develop good eye habits and do not "stop being short-sighted"!
Dr. Tao Yong warmly reminds
Even minor surgeries can be risky
Myopia surgery is no exception
But there is no need to be overly nervous
As long as you don't listen to or spread online rumors
Go to a regular hospital for a detailed eye exam
Choose the right surgical protocol with the help of a doctor
Risks can be avoided to the greatest extent

At present, there are 4 commonly used myopia surgeries: half-femtosecond laser (femtosecond laser), full femtosecond laser, ICL crystal implantation, trans-PRK surface laser.
Each method has its own advantages and disadvantages, as well as its applicable population. How to choose?

As mentioned earlier, after myopia surgery, there may be a phenomenon of "vision regression".
But don't be afraid!
It is recommended that people who watch the computer and work for a long time should reduce the time spent on the close eye 1 to 2 months after surgery and avoid fatigue.
Even after the postoperative recovery period, it is necessary to pay attention to the healthy use of the eyes, so that the eyes can be fully rested and prevent vision regression.
