The child is small and the cornea is not yet shaped, and wearing plastic lenses will not affect the

Hello: From an ophthalmologist's point of view, it is still not recommended that you wear this kind of orthokeratology lens, because after all, it is a rigid contact lens, and this lens is required to be worn at night, which will cause corneal hypoxia.

Lens adhesion. Orthokeratology lenses change the shape of the cornea by mechanically compressing the surface of the cornea, and the most affected part of this repetitive, continuous compression process is, of course, the corneal epithelium. The corneal epithelium is very fragile.

Long-term clinical observations and animal experiments have shown that mechanical compression of lenses can lead to chronic damage to corneal epithelial cells, so it is best not to wear them.

If you particularly want to wear it, you must strictly abide by the operation specifications, wash your hands carefully, avoid contaminating the lenses, lens cases and care solution, replace the lens case with a new one regularly, do not use expired care solution, you should follow the doctor's requirements for regular review, if there is any abnormality, you should contact the doctor in time.

A child's eye development is generally the same as that of an adult at the age of 6. It will not affect the development of children's eyes.

How old is the child, orthokeratology lenses are suitable for children aged 7-22, if they are too young, they are not suitable because the child does not have the ability to take care of himself. As long as orthokeratology lenses are suitable, they will not have any effect on the child.

The eyeball is fully developed at the age of 5 and can be worn around the age of 7.

1) There are misunderstandings in the understanding of orthokeratology**, with high expectations or unrealistic belief that this method can be myopia**.

2) Those with refractive error, those with anti-standard astigmatism, and those with "conformity astigmatism" are not suitable for night wear.

3) Patients with obvious intraocular astigmatism, and the ratio of spherical power to cylindrical power in corrected refractive error is less than 2.

4) Large pupils, especially those with large pupils at night.

5) Eye diseases: epithelial cell lesions, endothelial cell lesions, keratoconus, ** epithelial cell spotting, corneal intuition and severe dry eye and infection, inflammatory diseases, eyelid insufficiency, paralytic strabismus, nystagmus, lens opacity and acute and chronic glaucoma, acute inflammation of any active phase of the eye, chronic uveitis, chronic dacryocystitis, etc.

6) Systemic contraindications: severe diabetes, immune diseases such as rheumatoid arthritis and psychiatric patients.

7) Relative contraindications of individual conditions: those with relatively poor personal hygiene, poor compliance, and inability to review on time.

8) Those who are allergic to the ingredients in the care products.

People with eye diseases, such as corneal epithelial cell spotting, severe trachoma, keratitis, severe dry eye syndrome, too young, poor self-care ability, poor personal hygiene habits, etc., are not suitable for wearing.

If the contraindications are excluded, the degree of myopia is about or so, (the height number fitting needs to be combined with low-degree glasses during the day), and after strict vision examination, it is suitable for trial fitting, and those who can wear and re-examine as required can be fitted.

According to your condition, if your child has myopia caused by staying up late, overusing his eyes, and lack of outdoor exercise, and the myopia continues to increase, you can consider wearing a cornea. It is recommended to choose the ophthalmology department of a regular hospital for try-on, and only if you are qualified, you can customize it, when you usually wear it, you must pay attention to the hygiene of your eyes and hands, and you must review it regularly, when the body's resistance decreases, such as a cold, or there is inflammation and infection in the eyes, you should stop wearing it in time and wear glasses instead.

Orthokeratology lenses can correct and prevent the development of myopia, but they are not suitable for everyone. In addition to orthokeratology lenses, there are also means to control the development of myopia such as RGP, multifocal glasses, and low-concentration atropine, and you can also use your eyes in outdoor environments to develop good eye habits.
