After parents undergo myopia surgery, will the disease be passed on to their children?

"I can have surgery in the future anyway, and it will be over once and for all." I believe this is the self-comfort of many "glasses wearers" who wantonly squander their eye health and allow their eyes to get dilated. But is this really the case?

Mr. Zheng (pseudonym), 35, likes to play tennis and football, but his myopia of more than 800 degrees in both eyes makes it very inconvenient for him to exercise every time. Some time ago, after careful consideration, Mr. Zheng decided to have myopia surgery to get rid of the trouble of glasses. So he came to Aier Eye Hospital for treatment.

After a series of examinations, Mr. Zheng's eyes met the surgical conditions and could undergo myopia surgery. "Doctor, after the myopia surgery, are my eyes 'cured'? Will myopia not be passed on to the next generation?" he asked.

Doctors said: Under current medical technology, myopia cannot be "cured". The eye structure of myopic patients has changed. Myopia surgery only corrects the diopter, focusing the light on the retina to make the eyes see clearly, but it cannot change the elongated eye axis. Therefore, myopia surgery is only a correction method for myopia and cannot cure myopia.

Does having myopia surgery mean that myopia is cured?

Myopia surgery is not equivalent to curing myopia. Because true myopia is currently incurable. Generally speaking, the axial length of true myopia patients is longer than that of non-myopic people. The higher the degree, the more obvious the axial length becomes. If the eyeball of an emmetropia eye is a spherical ball, the elongated axial length of a myopic eye is an ellipsoid. Myopia surgery cannot shorten the axial length of the eye.

Therefore, rather than saying that myopia surgery solves myopia itself, it is better to say that it solves the problem of not wearing glasses. If the patient already has high myopia before myopia surgery, then after the surgery, the risk of eye diseases such as retinal detachment and macular degeneration caused by high myopia still exists.

After undergoing myopia surgery, is it possible that myopia can still be inherited?

Regardless of whether or not you have surgery, myopia has a certain probability of being inherited, especially for high myopia, and the probability of the next generation becoming myopic is higher. Of course, it does not mean that all myopic children are 100% myopic, but the probability of myopia is higher than that of non-myopic children.

Doctors remind: With current medical methods, no myopia surgery can "cure" myopia, and these surgeries cannot reverse the changes that myopia has already caused to the eyes. Therefore, whether you have normal vision, or you already have myopia, or you have normal vision after myopia surgery, you must protect your eyes.
