High myopia with bulging eyes is caused by the elongation of the eye axis, which is irreversible.

Myopia is when parallel light rays entering the eye are focused in front of the retina, after passing through the eye's refractive system, and thus cannot form a clear image on the retina. Myopia can be classified into low, moderate, and high degrees, with high myopia defined as 600 degrees or more. Once myopia progresses to true myopia, it is incurable, and one can only correct or control its progression.

Before the age of 18, myopia can only be corrected and controlled by wearing frame glasses or orthokeratology lenses; after the age of 18, elective surgeries like myopic correction surgery or artificial lens implantation are also available options for correcting myopia.

Is nearsightedness surgery safe?

Myopia surgery is relatively safe, but it is essential to understand the specific indications and contraindications before undergoing such a procedure. Firstly, myopia surgery involves operations on the cornea, including the creation of a concave lens on the surface, and intraocular procedures, such as the implantation of artificial lenses for those with lens-related issues. If there are other underlying retinal problems, these conditions are absolute contraindications. For surgeries on the cornea, it is crucial to measure the corneal thickness and rule out conditions like keratoconus. Once the contraindications and indications are properly assessed, these surgeries are very safe to perform.

Why can't true myopia be reversed?

True myopia is mainly characterized by the elongation of the eyeball, and the current medical level cannot solve the problem of eyeball elongation. Therefore, its nature cannot be changed, which means it cannot be reversed. Present treatment methods can only alleviate the symptoms of blurred vision when viewing distant objects in myopic patients, but cannot resolve the fundamental nature of myopia. Current treatment options include prescription glasses, orthokeratology lenses, contact lenses, and surgical treatments. Surgical options include corneal laser surgery and ICL (implantable collamer lens) surgery. After the onset of myopia, it is important to rest and use the eyes correctly to prevent further progression of the condition.

Does nearsightedness surgery involve holding the eyelid open?

Eye surgery, apart from eyelid surgery, requires the use of a speculum to hold the eyelids open to fully expose the field of vision for surgeries involving the eyeball and the inside of the eye. Myopia surgery, which involves the surface of the eyeball, also necessitates holding the eyelids open. The surgery can then be performed with the aid of a laser.

Children's myopia lacks which trace elements?

The relationship between myopia in children and the lack of trace elements is not significant. Myopia is generally caused by several reasons: The first is hereditary factors, where one or both parents may have myopia. The second reason is poor eye habits in children, such as sitting too close to the desk while doing homework, or excessive use of the eyes, like watching TV or spending a long time on mobile phones, which can easily lead to myopia in children. Once a child develops myopia, the degree could increase by 50-100 degrees each year. Thus, if this is the case, it is necessary to conduct a timely dilated optometry for the child to confirm whether they can wear orthokeratology lenses. If the child is over eight years old and all conditions are suitable, orthokeratology lenses can be prescribed to control the progression of myopia.

Can a child's 150-degree myopia be reversed?

Whether myopia of 150 degrees in children can be reversed depends on whether it is true myopia or pseudo-myopia. However, clinically, the vast majority of cases of 150-degree myopia are true myopia, so the chances of recovery are very small. Pseudo-myopia can be reversed through certain methods, such as protecting eyesight in daily life, developing scientific and reasonable eye habits, and regularly performing eye exercises. After a period, it is possible for the vision to return to normal. However, once true myopia occurs, current medical methods are unable to restore a child's vision to normal. Vision can only be corrected through methods such as wearing glasses, enabling the child's vision to reach a normal level. However, once glasses are removed, the child's vision remains myopic.
