Love has a “shelf life”, so does myopia surgery also have a “shelf life”?

I believe that most people have this simple and pure purpose for myopia surgery: to take off their glasses and regain stable and lasting good vision. Not only do they want to achieve satisfactory postoperative vision, but they also want long-term stability of vision. So how long can good vision after myopia surgery last? What affects it and what determines it?

What is myopia surgery for?

There are two main types of myopia surgery. One is laser myopia surgery, which involves making a concave lens on the cornea on the surface of the eyeball to change the refractive power; the other is lens implantation surgery, which involves implanting a permanent lens into the eye to change the refractive power.

Both surgeries are based on the patient's current myopia correction rather than a permanent cure. Therefore, the premise for postoperative visual stability is that the myopia degree is stable and does not change significantly.

Is myopia surgery effective in the long term?

Many people may feel a little panicked, thinking that if the degree of myopia changes after surgery, good vision will be lost. Don't worry, doctors and experts have also considered this issue.

Do you remember that the popular science said before: Myopia surgery is recommended for patients over 18 years old. This is because minors are in a critical stage of growth and development. In terms of eyes, myopia deepens quickly and vision is unstable. The reason is that the eye axis grows quickly. For every millimeter of eye axis growth, myopia deepens by a corresponding degree. If you have myopia surgery at this time, the possibility of myopia again after surgery is relatively high.

At the same time, the eyeball is a whole, and any problem in any part will affect the visual function. Therefore, before myopia surgery, the doctor needs to do a systematic and complete examination of the eyes to check for various eye diseases. If there are any contraindications, the myopia surgery will be rejected.

Therefore, if you are over 18 years old, your myopia degree is stable, and you have no contraindications, then myopia surgery can be effective for you in the long term.

Keep your eyes in good condition even after myopia surgery

If the above conditions are met, can you rest assured that your eyesight will be good? Can you play games and watch TV series all night long after the surgery? NO, NO, NO!

Zhang Qingsong, deputy chief physician, member of the Refractive Subcommittee of the Ophthalmology Committee of the China Association of Non-public Medical Institutions, and director of the Refractive Department of the Aier Eye Hospital affiliated to Wuhan University (Aier Eye Hospital Group Hubei General Hospital), reminds: Your eyes are not made of iron. After the operation, you must first follow the doctor's advice, avoid eye contraindications during the recovery period, and have regular checkups. Second, you must also develop good eye habits and cherish your eyes. Eyes are the windows to the soul, and eye protection is a lifelong career. Don't think that you have the capital to do all kinds of "eye-damaging behaviors" just because you have good vision after myopia surgery. Only by loving and protecting your eyes can you have long-term good vision.
