Myopia surgery has been developed for more than 80 years and is a blessing for many myopia patients. However, people are always full of doubts about this miraculous and unfamiliar surgery: Is there an expiration date for myopia surgery? Will I be nearsighted again after surgery? Will there be sequelae? Today, let's unveil the mystery of myopia surgery and answer your questions!
Many people have this question after myopia surgery: how long can the effect of this surgery last? Is it like a mobile phone, which needs to be replaced every few years?
In fact, there is no such thing as a "shelf life" for myopia surgery. In general, after rigorous preoperative examination and post-operative care, the results of myopia surgery can last for a long time, even a lifetime. However, that doesn't mean you can take your eyes lightly. Because, myopia surgery does not change the structure of your eyeball, nor does it prevent your eyes from developing presbyopia, cataracts, and other senile eye diseases as you age. Therefore, regular eye examinations and good eye habits are the keys to eye protection.
fromPrincipleAbove, there are two main types of myopia surgery, one is:Corneal lasersMyopia surgery, in which a concave lens is made on the cornea on the surface of the eye to alter the refractive power; One isLens implantation surgeryto implant a permanently usable lens into the eye to alter the refractive power. Both surgeries are based on the patient's current degree of myopia, rather than permanently** myopia.
1. Why does postoperative vision occur"**
Myopia surgery is based on the existing myopia degree for correction, like "tailor-made", tailored according to each person's unique "body", for most people, the possibility of myopia or regression after surgery is small, but there is no guarantee that each person's future "body will not change". Why do some people experience vision after surgery?
· In the short term
Generally, the "regression" that occurs within 3-6 months after surgery is related to corneal trauma healing and repair, which may be related to postoperative corneal epithelial remodeling and vision fluctuations caused by dry eye symptoms. This can be controlled by standardizing the use of postoperative eye drops.
· In the long run
Unscientific eye habits may lead to myopia again. For example, some people start to use their eyes for a long time after the first few months of careful care, such as facing the computer and playing with mobile phones frequently, which may cause the eye axis to continue to grow, resulting in myopia again. Secondly, we should also be alert to the protrusion or dilation of the cornea after refractive surgery, which is another disease that requires timely medical attention.
Therefore, to put it simply, the "regression" of vision after a few years after surgery is most likely due to the re-development of myopia.
2. Can myopia surgery be done for the second time?
If the prescription is stable and after a period of observation, the "regression" caused by other factors such as corneal and fundus problems has been ruled out, and the conditions for reoperation can be confirmed after a strict, accurate and comprehensive examination and review, and the conditions for reoperation are confirmed.
3. How to avoid postoperative regression?
· Review on time. It is very important to have a regular follow-up examination after surgery, as the axial changes caused by myopia will not be affected by surgery, so the follow-up examination is especially important for people who are prone to regression such as high myopia.
· Follow your doctor's advice. After surgery, it is necessary to follow the doctor's instructions to take the medication on time and according to the dosage, so that the postoperative tissue repair is within a reasonable range.
Develop good eye habits. It is necessary to pay attention to eye habits, especially in the first month after surgery, try to see more far, less near, control the time of near eye use, control the use time of electronic products, and prevent the myopia from continuing to develop due to improper eye use.
Whether you choose to have myopia surgery or not, remember that the eye is our window to the world and an important organ for us to perceive the world, please cherish it, protect it, and keep it healthy and bright forever. I will continue to provide you with more knowledge and information about eye health.
