Myopia correction surgery is not a one-time cure for myopia. If the eyes are used at close range for a long time after surgery, there may still be fluctuations in the degree. Regular sleep and scientific eye use are the key to postoperative vision protection. The causes of myopia and presbyopia are different, and the two do not "cancel each other out". After entering the middle-aged and elderly stage, myopic individuals may face both myopia and presbyopia problems simultaneously. In recent years, topics such as "mirror removal fever" have frequently appeared on the hot search list, and many people have turned their attention to myopia correction methods due to the needs of voluntary application, employment physical examination, and appearance improvement. Can myopia correction surgery fundamentally solve the problem? Can eye care products on the market improve vision? Do people with myopia not experience presbyopia? Faced with various issues, the reporter interviewed experts. Zhou Xingtao, chief physician of the Eye, Ear, Nose and Throat Hospital affiliated with Fudan University, pointed out that myopia correction surgery is currently a relatively mature vision correction method, mainly divided into two categories: laser (such as full femtosecond, half femtosecond) and artificial lens implantation surgery. The principle is to reshape the corneal shape or implant artificial lenses to improve the refractive state, thereby achieving the effect of correcting vision. But surgery is not a one-time cure for myopia, and if the eyes are used at close range for a long time after surgery, there may still be fluctuations in the degree. Regular sleep and scientific eye use are the key to postoperative vision protection. In response to the problems of eye fatigue and dryness caused by long-term use of electronic products by modern people, Zhou Xingtao shared a simple and feasible "20-20" principle: every 20 minutes of close eye use, look far for 20 seconds, and relieve eye fatigue through brief relaxation. Can various products such as "myopia prevention and control stickers" and "eye protection devices" on the market really prevent myopia and improve vision? Zhou Xingtao believes that there is currently no clear medical evidence to support the effectiveness of such products, and blind use is not recommended. He pointed out that the prevention and control of myopia should prioritize validated methods, mainly including three items: first, insisting on at least 2 hours of outdoor activities every day, even just walking can have a good effect; Secondly, using optical means, wearing OK glasses or functional frame glasses under the guidance of a doctor; The third is to use low concentration atropine and other drugs according to medical advice. Regarding the common misconception that "people with myopia will not experience presbyopia", Zhou Xingtao explained that the causes of myopia and presbyopia are different, and the two do not "cancel each other out". Myopia is caused by the elongation of the eye axis, resulting in blurred vision at far and relatively clear vision at near, while presbyopia is caused by a decrease in eye adjustment ability with age, leading to difficulty in approaching. Therefore, after entering the middle-aged and elderly stages, myopic individuals may face both myopia and presbyopia problems simultaneously. Is it feasible for middle-aged and elderly people to wear reading glasses without replacing them for a long time? Zhou Xingtao reminds that the degree of "presbyopia" may gradually deepen with age. When there is a blurry view up close or when reading requires holding a distance to see clearly, the reading glasses should be replaced in a timely manner. Wearing reading glasses with inappropriate prescription for a long time can keep the eyes fatigued and even accelerate vision loss. He also emphasized that if middle-aged and elderly people experience symptoms such as blurred vision, double vision, eye swelling and headache, and the presence of light circles at night, it may be a signal of eye diseases such as cataracts and glaucoma. They should seek medical attention at a regular diagnosis and treatment institution as soon as possible. Through examinations such as slit lamp microscopy and fundus microscopy, doctors can promptly detect age-related eye lesions. Especially for people with hypertension, diabetes or family history of eye diseases, it is recommended to have an eye examination every six months to one year. (New Society)
