Recently, some friends have completed myopia surgery, and they hope to be able to get rid of myopia completely "once and for all".
But today I want to give you a science popularization, myopia surgery is not a one-and-done thing.
Myopia surgery is not myopia, in fact, myopia is irreversible. Myopia eye surgery is only to correct myopia and not myopia.
In layman's terms, what myopia surgery can do is to help everyone "take off their glasses".
After myopia surgery, most people are unlikely to be myopic again after surgery, but there are also a small number of patients who continue to use their eyes unhealthily for a long time after surgery, resulting in regression of vision and relapse of myopia.
Therefore, friends who have no scruples after surgery must be cautious, use their eyes scientifically and rationally, and develop healthy eye Xi, otherwise they will "return to the pre-liberation period".
01. After myopia surgery, will I really be myopic again?In general, relapse myopia may be related to the following two points:
Preoperative power instability
Myopia surgery requires a stable refractive power for nearly two years, with an annual development of no more than 50 degrees.
From the perspective of surgical conditions, people whose myopia has been rapidly deepening in the past two years are not suitable for myopia surgery. If surgery is forced, there may be relapse of myopia.
Therefore, friends who want to have myopia surgery must have a strict preoperative examination and follow the doctor's advice.
Poor eye Xi
Some patients believe that after myopia surgery, it will be done once and for all. In fact, myopia surgery is only a way to correct myopia, not completely.
If the patient still has bad eye Xi after myopia surgery, such as using mobile phones, computers, staying up late, sitting improperly, etc., it is possible to become myopic again.
02. How to avoid myopia again after surgery?
Take precautions after surgery
It is recommended to wear polarizers when going out within one month after surgery to reduce photophobia, effectively protect the eyes, and reduce the damage of ultraviolet rays to the eyes
Wear goggles indoors (at your discretion) to protect your eyes from accidental bumps;
Go to sleep at night and wear an eye mask (2 weeks) to prevent rubbing your eyes during sleep.
Avoid overuse of your eyes.
Develop good eye Xi, 1 week to 1 month after surgery is a critical period for vision to stabilize, it is recommended to watch less TV, computer and mobile phone, avoid excessive eye use and stay up late, especially do not turn off the light to look at mobile phone;
Regular follow-up after surgery is key
It is recommended that patients have 6 reexaminations within one year after surgery, which are 1 day after surgery, 1 week after surgery, 1 month after surgery, 3 months after surgery, 6 months after surgery and 1 year after surgery, which is helpful for doctors to track the patient's eye recovery in real time and put forward targeted scientific eye suggestions.
03. What if I am short-sighted again?After myopia surgery, if the corneal thickness is sufficient and the eye condition is suitable for reoperation, then a second enhancement surgery can be done to correct myopiaIf you are not a candidate for surgery, you may be able to wear glasses as appropriate.
