For myopia surgery, many parents think that surgery will be done once and for all when their children grow up. But in fact, myopia surgery is not something that everyone can do.
Recently, the reporter learned in the Department of Ophthalmology of Taikang Tongji (Wuhan) Hospital that the number of people who came to consult myopia surgery has increased significantly since the summer. The hospital's ophthalmology department has more than doubled its outpatient and surgical volumes. Experts remind that although the technology has developed very maturely, not everyone is suitable for myopia surgery.
Cheng Qiong, deputy chief physician of the Department of Ophthalmology of Taikang Tongji (Wuhan) Hospital, introduced that the age is between 18 and 55 years old. Children under the age of 18 are not suitable for surgery because the development of the body and eye axis changes every year. Most people over the age of 55 have cataracts, so they are not suitable for surgery. If you have certain diseases, such as connective tissue diseases, rheumatoid arthritis, and some diseases of the autoimmune system, you cannot undergo surgery if you are at the stage of the disease. Professionally speaking, if the recent use of the eye is particularly large, it is necessary to assess whether there is a more serious dry eye syndrome, if the dry eye syndrome is very severe, you can consider waiting for the eye adjustment condition to be better before surgery.
In addition, myopia surgery requires different surgical methods for different individuals, and it is not the more expensive the better, the most important thing is to be suitable.
Cheng Qiong: "Myopia surgery is called laser surgery, which can thin our corneal tissue, so femtosecond laser requires that the cornea has no lesions, the cornea itself must be thick enough, and the degree should be lower, we will cut off about 20 microns of cornea for every 100 degrees of myopia, such as 400 degrees of myopia, we will cut off 80 microns, and the remaining corneal tissue must be enough to support future life." The second type is lens implantation, which puts a very soft material into the eye, which itself is a concave lens, to help see clearly. It is required that the internal environment in the eye must be good, the space of the eye must be large enough, and the depth of the front must be deep enough to be implanted. ”
Therefore, if myopic people consider myopia surgery, they first need to undergo a standardized examination to determine whether they are eligible for surgery. Also, myopia surgery is just one way to correct your vision. Patients with myopia can also correct their vision by wearing framed glasses, contact lenses, orthokeratology lenses, etc.
To prevent myopia, scientific eye use is fundamental. Getting enough sleep, getting your eyes in the sun, writing correctly, checking your eyesight regularly, eating vitamin-rich foods, and managing the use of electronic devices can all help your eyes feel less burdened.
Myopia surgery is a means to correct the current degree of myopia, not a way to cure myopia, nor can it prevent myopia. In the first two years of surgery, a myopia growth of no more than 50 degrees per year is considered to be stable myopia, and such patients usually do not develop myopia again as long as they do not overuse their eyes after surgery. Recurrent myopia often occurs when the preoperative prescription is unstable, the doctor's instructions are not followed after surgery, and the eyes are overused for a long time after surgery.
● People who often use their eyes at close range should reduce the time they spend near their eyes and avoid eye strain.
● People who use the computer for a long time should take a 10-minute break after 40 minutes of eye use to avoid excessive eye use.
● Avoid staying up late and do more outdoor sports.
● Avoid using your eyes in low light or using the electronic display for a long time.
In case of recurrence of myopia, a professional institution can be selected for a detailed assessment and examination of the ocular condition. For people with good corneal condition, secondary augmentation surgery can be an option. If a second augmentation surgery is not possible, glasses are the only option.
