Surgery for myopia and how effective it is

If you are highly myopic, you are also at risk of myopia complications such as retinal detachment, which is caused by your own myopia, not surgery. After eye correction surgery, the degree of myopia will decrease to a certain extent at a certain age (after the age of about 40). Correspondingly, if you have undergone orthopedic surgery, your vision will be slightly overcorrected or farsighted.

However, I advise you not to do this kind of surgery, because Professor Tsai Rui-fang of National Taiwan University Hospital, who first started this type of surgery in Taiwan, has stopped doing it, because there are still some complications in the long term, and the effect is not very ideal.

If you have chronic conjunctivitis, you must wait until your conjunctivitis has healed before you can undergo surgery.

If you have surgery, I don't know how tall you are now?

Myopia eye surgery can only be done if you are at least 18 years old.

Now, the best thing is femtosecond, but I don't know how old you are.

If chronic conjunctivitis is not too severe and the condition can be controlled for a period of time (i.e., it is not), surgery may be considered on the advice of a doctor. Generally, chronic non-infectious conjunctivitis will not have too much impact on myopia surgery, and myopia surgery can be done for chronic conjunctivitis before myopia surgery.

Only after the examination can you know which type of surgery is effective.

The main indicators for judging myopia are the degree of refraction and the change of the eye axis, rather than simple vision, which is mainly presented as the prolongation of the eye axis, which is irreversible, so it is impossible to achieve the reduction of myopia in children and adolescents, let alone **.

The purpose of myopia surgery is to correct myopia, and there are currently two main surgical methods: laser myopia surgery corrects myopia by cutting the cornea to change the refraction of light, while ICL lens implantation corrects myopia by implanting a lens with a prescription, and the myopia degree that they can correct can remain stable and unchanged for a long time. Therefore, if your myopia does not deepen further or other eye problems occur, then good vision can naturally be maintained for a long time.

Eye protection is not once and for all, and protecting your eyesight is a thing that requires long-term perseverance. Therefore, if you want to maintain good vision for a long time after myopia surgery, you should do the following:

1. Undergo myopia surgery in a professional and formal ophthalmic medical institution, ensure that the preoperative examination process is complete, systematic and standardized, and accept the operation under the premise of meeting the surgical conditions;

2. Adhere to good eye habits after surgery, reduce eye pressure, and avoid deepening myopia or other eye problems caused by excessive eye use;

3. Listen carefully to the doctor's advice, follow the doctor's advice, avoid relevant contraindications, and take medication on time and review regularly;

4. Patients with high myopia with a degree greater than 600 degrees have a certain risk of fundus lesions due to retinal traction and deformation caused by the extension of the eye axis, and myopia surgery will not increase or reduce the risk of this layer, and the fundus should be checked regularly once a year to avoid fundus lesions.

There are many classifications of myopia, and the need to wear glasses to improve vision is just one of the clinical manifestations of myopia. Myopia also involves fundus, corneal or lens lesions, and myopia surgery is a surgical change of glasses on the eye. For example, corneal refractive surgery, after the operation, it is equivalent to having a specific prescription of glasses on the cornea of the patient's eye, that is, the prescription of the glasses is transferred to the eyeball.

There are many classifications of myopia, ordinary simple myopia, pathological myopia, and can also be divided into primary myopia, secondary myopia, congenital myopia, and acquired myopia. If it is simple myopia, due to improper use of the eye caused by low and moderate myopia, this kind of myopia involves less other lesions of the eye, in this case, if corrected by myopia surgery, it is basically not very different from the emmepic eye of normal people. In the case of high myopia, the patient has fundus lesions, or corneal or lens lesions, and surgery cannot change these pathological changes.

Most of the causes of myopia are the elongation of the eye axis, which cannot be shortened by surgery, but by changing the form of the glasses, it is commonly understood that a pair of glasses is made on the cornea. Now myopia surgery is called corrective surgery, and it is not called ** surgery by standard.

True myopia, also known as axial myopia, refers to the fact that the anterior and posterior axis of the eyeball (eye axis) becomes longer due to congenital or acquired factors, resulting in the focus of light entering the eye and the focus cannot be accurately focused on the retina, so that things cannot be seen clearly.

Under normal vision, the average axial axis of the eye is about 24mm, and when light enters the eye, the focus falls accurately on the retina. In myopic eyes, the focus falls before the retina due to the elongation of the eye axis, and in the hyperopic eye, it falls behind the retina. The eye axis cannot be shortened in the same way that a teenager cannot become shorter after growing taller, or the hair of an elderly person cannot be reversed after it has turned gray.

Therefore, with the current technology, true myopia is not possible.

How does myopia surgery restore vision? Since the eye axis cannot be shortened, there are other ways to help myopic eyes correct their vision. For example, eyeglasses and myopia surgery. The principle of eyeglasses and myopia surgery is the same.

Glasses only wear a concave lens lens in front of the eyeball of the myopic eye, while laser myopia surgery is to make a concave lens on the cornea through a laser, although the position of the concave lens is different, but the function is the same, both allow the light to be accurately focused on the retina again. Lens implant myopia surgery involves implanting an ultra-thin miniature concave lens lens directly into the eye that can be used for life.

Although neither of them has **myopia, but they both help you see clearly, but the glasses must be on the bridge of the nose at all times with the help of glasses, which increases the trouble of wearing glasses.

Myopia eye surgery is first of all subject to age restrictions, generally over 18 years old, with stable vision for more than two years, and many people over 40 years old are allowed to undergo myopia surgery. This is just the basics, and a detailed examination is usually required before surgery to see if your condition is suitable for surgery. and whether surgery can be done.

Some people may ask why laser surgery must be over 18 years old, this is because those under 18 are in the stage of vision development, and myopia in this period can be enhanced and improved or even restored by supplementing Leeye vision nutrients, so those under 18 years old are not operable, and timely intervention can restore vision. However, after the age of 18, because the vision has been fixed, the acquired attention and maintenance can only maintain the eyesight and no longer grow.

If you are suitable for myopia surgery, you should pay more attention to postoperative maintenance after doing it, which is the fundamental.

After surgery, we should continue to take care of our eyes, and the measures to prevent myopia should be lifelong, otherwise it can cause new myopia, and there are often new myopia in the outpatient clinic for a certain period of time after surgery, and some people's vision decreases a lot.

Therefore, you still have to take care of your eyes, don't over-fatigue and overuse your eyes.

The cornea cannot be laser cut multiple times, otherwise keratoconus will occur, and it will be troublesome.
