Orthokeratology is a new technology for non-surgical correction of myopia, which has good results in myopia correction and prescription control. It is designed according to the wearer's corneal geometry and refractive power, and is made of highly oxygen-permeable material for eye measurement, so it can maintain good naked eye vision as long as it is worn at night. It is the most effective for the correction of myopia in children and adolescents, and it is an advanced technology that effectively controls the progression of myopia for a long time.

Adolescents with myopia below 600 degrees can consider orthokeratology lens technology, which can control the development rate of myopia within 50% or even 30% of conventional glasses, and is especially effective in preventing the development of myopia in adolescents.

At the same time, orthokeratology only needs to be worn for 8-10 hours at night when sleeping, and the distance vision will be significantly improved during the day, which is very convenient to wear and use (Medigo orthokeratology lenses).

Hello dear, orthokeratology lenses are suitable for correcting myopia from 100 degrees to 500 degrees. Orthokeratology lens is a commonly used means of correcting myopia, by wearing orthokeratology lens while sleeping, exert pressure on the cornea, change the curvature of the cornea, and achieve the effect of clear vision without glasses during the day, and at the same time, it can also delay the growth of myopia by eliminating the peripheral defocus phenomenon. Orthokeratology lenses have a better effect on myopia correction over 100 degrees and below 500 degrees.

When the myopia is lower than 100 degrees, it is not very effective in controlling the growth of myopia, and when the myopia is higher than 500 degrees, it is easy to cause complications such as corneal damage.

Orthokeratology lens wearing conditions:

1. Age 7-40 years old, healthy, no eye problems;

2. The curvature is between 40d and 46d;

3. The degree of myopia is below 600 degrees, and the astigmatism is below 100 degrees.

Orthokeratology lenses are divided into domestic and foreign, ** cheap in thousands to tens of thousands of domestic countries, imported ones are a little more expensive, but imported technology, materials and processes are much higher wearing comfort is not the same, a little better such as the United States Wilma, I hope to help you.

Orthokeratology lenses have been included in the medical equipment, which need to be fitted by a professional fitting specialist in a regular hospital, and various examinations are required before fitting, such as intraocular pressure, corneal topography, slit lamp, optometry, etc., and then try it on, as long as it is suitable for wearing, pay attention to hygiene and recheck it regularly, there will be no problem. Professional hospitals can make accurate examination results, in order to dispense qualified glasses, to make the correct treatment of some situations, I heard that Shandong visual defense is good, in many cities local hospitals have sub-centers, you can go to consult, I hope it will help you and be adopted.

In myopia, the eyeball is elongated, and orthokeratology lenses use external force to force the eyeball to temporarily press the eyeball to a normal level, so that the vision remains normal for a day.

Do you know how "orthokeratology lenses" can control myopia?

Through a series of examinations (corneal thickness, intraocular pressure, corneal curvature, corneal topography, etc.), corneal curvature greater than 46 can not be worn, in the case of suitable wearing, orthokeratology lenses are made by the curvature of the cornea is reduced, in short, the cornea is flattened, through overnight wearing, myopia will be reduced, and the next day is not to wear glasses.
