Why can’t myopia be “cured”?

Abstract: with the continuous development of ophthalmic medical technology, laser myopia surgery is becoming more and more mature.

and

are common concerns of parents of myopia children. Many people mistakenly believe that the reduction of the degree represents the cure of myopia, but in fact, the fundamental complication factors of myopia have not been eliminated, so myopia can not be “cured”.

this also starts from the principle and treatment of myopia. Children’s myopia is generally divided into true myopia and false myopia. When children have vision problems, they should first go to a regular eye hospital for mydriatic optometry and related visual function examination.

pseudomyopia

when looking at near objects, due to the strong degree and long duration of adjustment, the ciliary muscle contracts continuously, resulting in adjustment tension or adjustment spasm. Therefore, when turning to look far after reading and writing for a long time, it can not relax the adjustment quickly, resulting in decreased vision, and may be accompanied by dizziness, eye swelling and other visual fatigue symptoms, This is a temporary myopia caused by abnormal eye function, which is called pseudomyopia.

true myopia

true myopia belongs to organic changes. After using ciliary muscle paralysis, it still shows myopia, which is essentially different from pseudomyopia. This is true myopia.

how to distinguish between true and false myopia

first need to go to the hospital or optometry Center for optometry to confirm whether it is true myopia or false myopia.

if it is pseudomyopia, relevant visual function training is needed to restore vision.

if it is true myopia, it is necessary to formulate a scientific optical correction scheme, including wearing keratoplasty (MCT), breathable contact lenses (RGP), or frame glasses.

why can’t

myopia be treated well? The main causes of true myopia are the growth of ocular axis and the lesions of fundus. For a popular example, this is the same as a child’s long stature. It is impossible to be short when you are tall. Comparison of various correction methods for

true myopia

frame glasses

wearing frame glasses is the most common method. The biggest advantage is that it is economical and simple, but it often causes a lot of inconvenience to life. Especially for some special myopia patients, there are still some limitations, especially high myopia will cause the reduction and deformation of the real image.

myopia surgery

with the continuous development of ophthalmic medical technology, laser myopia surgery is becoming more and more mature. Taking the current mainstream femtosecond laser myopia surgery as an example, there is no knife in the whole operation, which is safer, more accurate, closer to the original corneal state, and the postoperative visual quality is more perfect. However, because myopia surgery is a myopia correction method for adults over 18 years old, and has strict preoperative examination requirements and indications, it is not suitable for myopia teenagers who are still in growth and development.

rigid corneal contact lens (RGP)

Polymers such as silicon and fluorine contained in RGP can greatly increase the throughput of oxygen. Compared with soft contact lenses, it not only improves the oxygen permeability, but also ensures the firmness of the material, and has good wettability and anti precipitation. Its effect of controlling and correcting juvenile true myopia and keratoconus has been verified by ophthalmologists at home and abroad for many years, and has been affirmed.

keratoplasty (MCT)

MCT is a rigid breathable contact lens with inverse geometric design. It is customized according to the shape of the wearer’s cornea. Through wearing, the elastic cornea can be gently and painlessly reshaped, so that the central part of the cornea tends to be flat, so as to change the refractive state of myopia, improve far vision and restore its clear state. Users can enjoy clear naked vision the next day as long as they wear it for 7-8 hours at night. Compared with traditional frame glasses,

and

, MCT can more effectively control the development of juvenile myopia, so that myopia increases by only 17 degrees or less every year, while wearing ordinary frame glasses increases by 85 degrees every year. The effect of MCT is five times that of it, and it has obvious advantages in safety and convenience.
