At the National Two Sessions in 2022, some representatives suggested that all myopic people aged 18-45 should undergo surgical correction.
Someone has a question:
“Many ophthalmologists also wear glasses. They don’t do myopia surgery themselves, so why let others do it? Isn’t it safe?”
For the answer to this question, let’s see what Tao Yong, the “professor of ophthalmology without glasses” has to say…
Maybe it was surgery, but you don’t see it?
Some ophthalmologists don’t do myopia surgery, not because they don’t believe in the surgery, but because they don’t need it.
Because surgery or not, it doesn’t affect him seeing a doctor.
Ophthalmology treatment is mostly done under microscopic conditions, requiring the help of an operating microscope, but not too much for uncorrected vision.

Therefore, it is the doctor’s personal choice to do or not to perform myopia surgery.
After all, an ophthalmologist who can treat people’s eye diseases is the best ophthalmologist!
The word “sequelae” sounds scary. Especially moving the knife on the delicate eyes, it is inevitable to make people feel guilty.
But don’t be afraid, the most common clinical observations about the discomfort after myopia surgery are dry eye syndrome and visual regression.
1. Dry Eye
Operation may damage the ocular nerves and corneal epithelial cells, disrupt the eye’s adjustment function, and affect the secretion of tears.
Lack of moisture from tears results in dry eyes[1].
However, as the cornea heals itself, the symptoms of dry eye disappear [2].
2. Vision regression (progressing myopia)
Mostly, myopia deepens due to poor eye habits and heavy eye burden after surgery.

Generally speaking, after the degree of myopia in adults tends to be stable, as long as they undergo strict pre-operative examination, follow the doctor’s instructions, use the eyes reasonably, and review regularly after the operation, there will be basically no vision loss. back situation.
However, for patients with high myopia (above 600 degrees), due to the elongated eye axis, they are often accompanied by fundus lesions. Although the visual acuity improves 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 be short-sighted again [3].
If you want to correct myopia after “re-myopia”, the difficulty and sequelae will be greatly improved.
Therefore, you must develop a good eye habit after surgery, and don’t be “short-sighted” again!

Dr. Tao Yong’s warm reminder
Small surgery can be risky
Myopia surgery is no exception
But don’t overdo it
As long as you don’t listen and don’t spread online rumors
Go to a regular hospital for a detailed eye examination
Choose the right surgical plan with the help of your doctor
Minimize risk
Achieving the best surgical outcomes
There are 4 types of myopia surgery commonly used at present: half-femtosecond laser (femtosecond laser), full femtosecond laser, ICL lens implantation, Trans-PRK superficial laser.
Each method has its own advantages and disadvantages, as well as the applicable population. How to choose?

As mentioned earlier, after myopia surgery, there may be a phenomenon of “regression of vision”.
But fear not!
It is recommended that people who look at the computer and work at a desk for a long time should reduce the time of using their eyes at close range for 1 to 2 months after surgery to avoid eye fatigue.
Even after the post-operative recovery period, you should pay attention to healthy eye use and allow your eyes to get enough rest to prevent vision loss.
How do I protect my eyes?
Remember the following 4 eye care tips after myopia surgery!
Dr. Tao Yong’s warm reminder
1. Myopia surgery can only correct, not cure myopia
2. Myopia surgery is not for everyone
If you want to do it yourself, consult an ophthalmologist before deciding
