Who knew if it was good for kids to wear orthokeratology lenses?

As long as the examination is qualified, there is no harm in wearing it for the eyes. If you wear glasses at night, you can get clear vision all day long by removing them during the day. Wearing orthokeratology lenses for children is a commonly used means in clinical practice, and wearing orthokeratology lenses can help slow down the progression of myopia, but eye hygiene should be paid attention to when wearing orthokeratology lenses to prevent eye infection.

It is recommended that parents take their children to a regular hospital for a standardized examination, so that a professional doctor can give wearing advice. Avoid delaying the condition and delaying the opportunity.

The keratoscope worn by children is also known as orthokeratology lenses. Orthokeratology lens is a special hard contact lens worn on the eye, worn when sleeping at night, and does not need to be worn during the day, it is also called OK lens. If the degree of myopia is relatively low, such as less than 200 degrees of myopia, wear OK lenses every night, OK lenses play a role in shaping the cornea, and the prescription may return to normal after a period of time.

For more advanced myopia, it can be prevented from progressing further by wearing orthokeratology lenses. The time for wearing contact lenses should be around seven years old, and children below this age are not easy to cooperate, and there are also reasons for hygienic conditions, so it is recommended to wear orthokeratology lenses around seven years old. Wearing orthokeratology lenses to prevent the occurrence of conjunctivitis, before wearing the corresponding examination, children with eyelid entropion trichiasis should first cure the eyelid entropion trichiasis, in order to avoid conjunctivitis and keratitis caused by plastic lenses.

In fact, as long as the child is at least 6 years old, he or she has already met the preliminary fitting conditions of orthokeratology lenses, and can consider checking and wearing! In addition, as long as the child has a certain degree of self-care ability, he can use and take care of orthokeratology lenses on his own. It is important to note that:

The lenses are cleaned every day and the care solution is changed every day to ensure the safety and hygiene of orthokeratology lenses.

Parents may not be very clear that orthokeratology lenses have high requirements for the wearer's daily hygiene and lens care due to direct contact with the eyeballs. If hygiene is not done properly, it may cause eye inflammation. Therefore, the procedure should be carried out according to the instructions of the dispensing physician.

However, there are still parents who are skeptical about their children's orthokeratology lenses and wonder whether it is really safe for their children to wear orthokeratology lenses.

Age is not the main issue, the key is to first look at whether your child's overall eye examination is suitable for wearing, and secondly, to choose the right orthokeratology lenses, and regular follow-up and communication with the hearing care professional are very important. Orthokeratology lenses themselves are safe, the key is to see how to operate, if the child itself is not suitable to wear, it must not be worn, the later operation must follow the doctor's instructions, and there will be no problem with regular reexamination. “

As for corneal epithelial scratches, it is also a small probability event that may occur due to improper operation, and this may also happen when rubbing the eyes, so just follow the doctor's instructions. Because orthokeratology lenses are third-party medical devices, they must be fitted by professional medical personnel in medical institutions to ensure the safety and effectiveness of their wearing. ”

Great, the U.S. Food and Drug Administration (FDA) and China (SFDA) have both approved the use of high-quality night-wearing orthokeratology lenses, both of which have been clinically validated. Among them, orthokeratology lenses are now used in the ophthalmology departments of many hospitals, and you can consult and examine Puri Ophthalmology, which is a well-known professional ophthalmology chain medical institution in China.

IQ test, doctors nowadays dare to do anything for money. The only way to deal with myopia is to wear suitable glasses, correct incorrect lifestyle or study habits, and set aside half an hour every morning in the morning, noon and evening to do eye attention exercises at the farthest and nearest points. In order to effectively delay myopia.

6.Consider a professor who is writing a book. The professor was faster at writing books and collecting the data he needed than anyone else at his university, but he still had to pay students to collect data in the library. Is it wise to do so? Explain why.

When we feel that life is not going well, we always complain about our bad luck, but have you calmed down and thought about it? How much hardship have you endured, how many hardships have you experienced, and you feel unsatisfactory again. We all know that hard work may not lead to success, but continuous failure after hard work is also the wealth of life, and living to die is such a truth.

People's good luck will run out, and bad luck will run out of luck, there will always be a day when it will run out. Those failures accumulated after hard work will also become a road rage that has become a long-term illness, and this is the turning point of good luck. Some people may say that he is so much smarter than me, and I can't keep up with him no matter how hard I try, and then I simply give up.

In fact, this is just an excuse to make people stranded and content with the status quo. What's more, you can't even work hard with others, let alone fight for talent. In fact, intelligence is only an attribute of a few.

If you don't have this attribute, you can also be a sincere person, an upright person, a simple person, a hardworking person, a beautiful person......Because this world is not something that can be supported by intelligence alone. I once heard a saying: people around you ask you to study hard, not because they want you to compare your grades with others, but because they hope that you will have the right to choose meaningful and time-bound work in the future, rather than being forced to earn a living.

Strive to become a better version of yourself, as long as you are good enough, you are worthy of all the good in this world, and you can choose the life you want. It is said that the most important thing is persistence, but persistence is hard work. The harder you work, the luckier you get, and the 100% effort may get a 1% result, but as long as you have faith, the harder you work, the luckier you are.

I'm sure we'll get something out of it!

Summary. The following situations should never be equipped with orthokeratology lenses:

1. Ocular diseases, such as patients with diseases on the surface of the eye, degeneration of epithelial cell stromal membrane, endothelial cell degeneration, ** epithelial cell spotting and severe dry eye patients, infection, ptosis surgery, inflammatory eye diseases, etc.

2. Poor self-care ability and poor personal hygiene habits.

3. Those who cannot follow up the observer as required, and those who have poor compliance with wearing and follow-up.

For patients with obvious corneal astigmatism (astigmatism is greater than corneal curvature, too large or too small (general curvature is better in effect), large pupils, small palpebral fissures, mild ptosis, excessive eyelid strength, sensitive eyes, high myopia (myopia greater than mild trichiasis, etc., it will also affect the effect of wearing orthokeratology lenses).

Orthokeratology lenses make it difficult to "get close".

For the prevention and control of myopia in adolescents and children, a safe, effective and easy-to-operate method is a good method.

At present, the maximum power of orthokeratology lenses approved and registered by the State Food and Drug Administration is 600 degrees. High myopia of more than 600 degrees will affect the wearing effect.

A pair of lenses is generally about 10,000 yuan, and it needs to be rechecked every 1 week, 1 month, 3 months, and 6 months in the early stage, and then it needs to be rechecked every 6 months, and the lenses generally need to be replaced in 1 year. From the onset of myopia to the age of 18, orthokeratology lenses will be a huge expense.

Why don't you give your child orthokeratology lenses?

From the onset of myopia to the age of 18, orthokeratology lenses will be a huge expense.

In terms of wearing time, the wearer must ensure that he wears it for 8 to 10 hours a day, but the sleep duration of primary and secondary school students is difficult to achieve. This can explain why orthokeratology lenses are so good, but myopic children rarely choose them.

Before the pros and cons of orthokeratology lenses, let's talk about a concept, what are orthokeratology lenses!

Orthokeratology technology is a lens designed with a special inverse geometric shape, the inner surface of which is composed of multiple arcs, which is worn on the front of the cornea while sleeping, gradually flattening the curvature of the cornea and shortening the eye axis, thus effectively controlling the development of myopia, and is known as "the technology that can control and correct myopia while sleeping".

Its advantages are that the process of orthokeratology correction of myopia is safe, reliable and effective. Wear glasses at night to restore normal vision during the day. Long-term wear can effectively delay the growth rate of myopia.

Of course, there are also advantages and disadvantages, although orthokeratology lenses use physical correction methods to effectively control the progression of myopia, but they cannot be myopia, and there is still no myopia method in medicine. At the same time, orthokeratology lens wearers also have certain requirements: there can be no inflammation in the eye, such as conjunctivitis, keratitis, etc., must be in accordance with the requirements of expert teachers, there are certain health requirements, and the cost is relatively high.

It is not suitable for children in ordinary families. The cost is generally about 6,000 to 10,000 yuan, and the annual cost of care products is also more than 1,000 yuan.

Shuangdong orthokeratology glasses, this may be a new product, we don't know, but I want to advise you, you don't listen to the business publicity, they often expand their words, it's best to ask, who has used it? This is a good grasp of something.

At present, the level of medical technology can not ** myopia, but can only control its progression rate, the control range is between 40% and 60%, which is the most effective of all the optical methods to intervene in the progression of myopia. That is to say, if the child grows 100 degrees in 1 year, and the growth is about 50 degrees in 1 year after wearing keratos, of course, every child is not exactly the same, a small number of children are less than 50 degrees, and some are more than 50 degrees.

As we all know, myopia has the condition of blurring and squinting in the distance. Newborn babies have not yet grown and developed their eyeballs thoroughly, and they are more hyperopia, with the eyeball about 17mm in front and back, with the growth and development of both eyes, the eyeball slowly expands, the front and back left and right diameters slowly increase, and the degree of hyperopia and myopia slowly decreases, and at the age of 1 2, the degree of hyperopia and myopia is in 2 3d (diopter).

With the further improvement of the eyeball, this kind of hyperopia reserve will gradually decrease, and myopia occurs when the parallel-plane light source passes through the refractive system software of both eyes and cannot image the macula of the fundus in 3D, but only in front of the macula of the fundus. Myopia is a disease that is interfered with by multiple factors such as genetic inheritance and natural environment. Myopia is irreversible, but it can be prevented.

Orthokeratology lenses are generally suitable for myopia patients between the ages of 6 and 18, and the benefits outweigh the disadvantages of grasping all the normal wearing methods. If children cannot cooperate effectively with each other, wearing orthokeratology lenses will cause undesirable harms, such as myopia in both eyes due to lens movement, myopia in both eyes, conjunctival inflammation, etc.

It is recommended to wear orthokeratology lenses under the guidance of a doctor, and be sure to maintain the hygiene of the spectacle lenses to prevent corneal diseases. Follow-up eye and vision check-ups for children and adolescents on time. Orthokeratology lenses for children can bring good practical results.

Generally, it is very likely that myopia in children is caused by genetic factors, and it is also possible that it is a long-term TV series or playing with electronic devices, which is likely to lead to myopia in both eyes. In daily life, you must pay more attention not to overuse your eyes, and try to avoid looking at your mobile phone.
