What are the pros and cons of orthokeratology lenses?

As far as I know, the pros and cons of orthokeratology lenses are as follows:

The advantages of orthokeratology lenses are: 1. It can only be worn while sleeping, and can maintain stable vision without wearing it during the day. So it's very convenient.

2. Studies have found that it also plays a certain role in delaying the progression of myopia in children. 3. If the degree of myopia is not too high, the vision can be restored to the best state after wearing orthokeratology glasses for a long time.

The disadvantages are: 1. In the case of improper nursing, it may cause corneal damage, cut cornea, and secondary infection. 2. Orthokeratology lenses are only limited to people with myopia within 600 degrees, and the effect is not good for myopia above 600 degrees.

3. **It is more expensive, generally it needs to be replaced once after 1-2 years, which will cause a certain burden to ordinary families.

If you need orthokeratology lenses, we recommend that you go to Meiermu Hospital. Founded in 1988, in the past 30 years, Beijing Meiermu Hospital has given full play to the advantages of private group hospitals, attracting a large number of well-known domestic experts from Tongren, Xiehe, 301, People's Hospital and so on.

Form an authoritative medical team. The annual outpatient volume exceeds 300,000 person-times, and more than 80,000 cases of various surgeries, and nearly 10,000 patients with incurable diseases transferred from Beijing, Guangdong, Sichuan, Tianjin and other places are accepted every year.

Advantages: Professional doctors comprehensively examine and design reasonable orthokeratology lenses, under the premise of scientific fitting, correct use and regular examination, can enable most myopia patients to improve their naked eye vision in a short period of time. In addition, orthokeratology can correct myopia with a degree of 600 degrees and corneal astigmatism up to 150 degrees, and high-quality orthokeratology results appear after 7-21 consecutive nights, and generally last about 10 hours of free naked eye vision during the day.

Disadvantages: Not suitable for patients with high myopia above 600 degrees, not everyone can be fitted, and patients with low systemic immunity can only be determined after passing the examination, and the use period is 1 to one and a half years and needs to be replaced.

Pros: The process of myopia correction with orthokeratology lenses is safe, reliable and effective. The application of high-tech materials, the innovation of lens design and the computerization of production and processing are the keys to the great success of orthokeratology lens technology and its wide acceptance by doctors and patients.

Patients with mild or moderate myopia who use orthokeratology lenses have a significant reduction in refraction and a surprising improvement in vision in a very short period of time.

Disadvantages: Orthokeratology lenses are made of breathable rigid contact lens material, and the lenses need to be cleaned daily, and friction during the process will leave scratches on the surface of the lenses. Over time, increased scratching can lead to decreased oxygen permeability to the lens, protein deposition, corneal epithelial damage, pain, and conjunctival injection.

Therefore, each pair of lenses will have a service life, and the replacement cycle stipulated by the State Food and Drug Administration is 1 year.

Adolescents with abnormal intraocular pressure who are fitted with plastic lenses may experience severe corneal epithelial detachment, inflammation, corneal infection, and even blindness, but these are all eye infections caused by unhygienic procedures.

In fact, the safety of orthokeratology lenses is largely related to the user's hygiene habits, the user needs to complete the cleaning and disinfection procedures according to the specifications, in addition to the necessary regular review after wearing, if there is eye discomfort during wearing, the lens should be removed immediately and the doctor should be seen in time.

Under the premise of good communication, understanding and cooperation with patients, a large number of cases and clinical practices have confirmed that orthokeratology lenses are safe, controllable and effective.

Orthokeratology lenses can correct myopia, what are its advantages and disadvantages?

Orthokeratology is a special design for patients with refractive error (myopia, farsightedness, astigmatism, presbyopia) to wear a specially designed, high-tech orthokeratology lens lens made of high oxygen permeable materials during night sleep, which can significantly improve the naked eye vision when getting up during the day, without any glasses. In order to achieve the temporary elimination or reduction of myopia, farsightedness, astigmatism, presbyopia, etc., and effectively slow down the development of myopia, a medical technology for the purpose of this medical technology.

A orthokeratology lens is currently an effective means to control the development of myopia, which can effectively slow down the decline of myopic vision, provide clear naked eye vision, and can be operated without glasses during the day. After wearing orthokeratology lenses, the corneal morphology changes, resulting in improved vision, and the vision will gradually decrease after stopping wearing.

Although orthokeratology lenses have advantages, they also have disadvantages, such as being expensive, more frequent nursing operations and re-examinations, high requirements for hygienic conditions, and more troublesome than glasses. Some patients are not suitable for wearing orthokeratology lenses, such as dry eye syndrome, thin cornea, corneal ulcers, and keratitis patients are not suitable for wearing orthokeratology lenses.

bIf you choose orthokeratology lenses, you must follow the doctor's review, examination and reasonable care. The requirements of orthokeratology lenses are relatively high, and for those with relatively good hygienic conditions, aseptic operation must be carried out to achieve a reasonable and effective application method to control the development of myopia, rather than self-wearing. Orthokeratology lenses are worn for a certain period of time, and the product needs to be replaced in about one to one and a half years.

Remind orthokeratology lens patients to go to the hospital for regular check-ups to avoid adverse damage caused by orthokeratology lenses.

cThis lens has a special design that is opposite to the shape of the cornea. Like a "mold", a new corneal shape is reshaped through the pressure of the eyelids, lenses and the hydrodynamic effect of tears, thereby reducing or increasing the refractive power of the cornea, and reducing or even eliminating the degree of myopia, farsightedness, astigmatism and presbyopia. However, the cells of the corneal epithelial layer are memorable, and they will gradually return to their pre-lens form after stopping.

Therefore, the effect of orthokeratology lenses in reducing myopia is temporary, and it needs to be worn for a long time to maintain the effect.

The pros and cons of orthokeratology lenses, first of all, orthokeratology lenses have appeared in the American market in the 90s, called OK lenses, and then successively introduced to China, and were abandoned at first, because of the damage to the cornea, in the case of improper care, it may cut the cornea and secondary infection, which is a very obvious disadvantage. As for the subsequent return to the market, in addition to the improvement in quality and production materials, there are also advantages that cannot be ignored, such as the ability to wear it while sleeping, but not during the day, and maintaining stable vision. For athletes, actors, or children on campus, it is indeed a very good thing to be able to run freely in the sun without wearing glasses during the day, so it is considered to have obvious advantages.

In addition, big data show that it has a certain role in delaying the progression of myopia in children, although it cannot deify the relative effect, but after all, it needs to be confirmed by more data. As for the disadvantages, in addition to the corneal damage that may be caused by improper care, orthokeratology lenses are only limited to myopia within 500 degrees, and the function of myopia above 500 degrees is not optimistic. In addition, it is more expensive, if it needs to be replaced once in 1-2 years, it will cause a certain burden on wages and ordinary families.

Orthokeratology lenses have the ability to control the degree of myopia no longer or slow down the progression, and get rid of the hassle of wearing glasses during the day. The disadvantage is that it is not suitable for patients with deep myopia of more than 600 degrees, and if the cleaning is not in place, it is easy to cause ophthalmic inflammation. Physician Advice:

Orthokeratology lenses can generally be divided into two stages: the first period and the maintenance period. Precautionary measures: It is recommended to go to the ophthalmology department of a regular hospital for professional selection of orthokeratology lenses, and once the symptoms of eye discomfort appear, it is necessary to stop using them and seek medical attention in time.

Orthokeratology lenses are mainly for people with myopia below 600 degrees and astigmatism below 175 degrees. For patients with myopia above 600 degrees, they need to wear glasses during the day to maintain the needs of daytime work and study. Patients under the age of 18 have the effect of controlling the increase in power.

My colleague's child wears this, it is matched in the east --- south, myopia is 300 degrees, and the degree changes very little after wearing it for a year. The disadvantage is that it is not cheap, and it may not be suitable for those who are not very good in economic conditions.

Orthokeratology lenses can reshape the cornea of the eye, so that the first part of the cornea tends to be flattened, so as to change the refractive state of myopia and improve vision. Advantages of orthokeratology lenses: 1. Vision can be improved in a short period of time; The refraction of myopia decreases rapidly, and the glasses can generally be removed in a week or two.2 It is simple to use without changing the normal physiological structure of the eyes.

Disadvantages: 1. There is an age limit 2. You must insist on wearing it, 3. ** is higher.

The harms are as follows: 1. It cannot completely block the development of myopia, nor can it make the existing myopia disappear; 2. If the child does not wear it for a few days, the shape of the cornea will spring back, and the vision will also decrease; 3. Wearing orthokeratology lenses has certain risks and needs to be worn carefully. The use of orthokeratology lenses is a strict medical practice and must be done at a professional, certified medical institution.

4. The scope of application is relatively narrow, most brands are only limited to 500 degrees of myopia, and the requirements for corneal morphology are also high, and not everyone can wear it.

The advantage is that it can correct vision, and it is the kind of correction method that has a long-lasting effect and can basically help everyone to restore the eyes to their previous state more easily. The disadvantage is that it is really uncomfortable to wear because of the use of plastic lenses during correction, and it is necessary to go to the hospital for examination frequently during the correction process, which will also delay a lot of time and energy.

The advantage of orthokeratology lenses is that they can see very clearly during the day without wearing glasses, because orthokeratology lenses are worn at night when they sleep, and secondly, this type of orthokeratology lenses can correct children's vision. But it also has obvious disadvantages, that is, the ** of the shaping mirror is relatively expensive, at least more than 1,000 yuan, and it has to be replaced once in a year or two. In addition, the hygiene requirements of plastic lenses are very high, and if you are not careful, you will get infected.

1. The advantage of orthokeratology lens is to correct myopia astigmatism and control its development at the same time;

2. The disadvantage of orthokeratology lenses is that there is a risk of corneal infection;

3. In general, the advantages of orthokeratology lenses outweigh the disadvantages, and its disadvantages can be completely controlled in regular professional eye hospitals. For example, the M3D orthokeratology technology of Beijing Mingshi Ophthalmology is both controlled and safe!

Orthokeratology lenses are a hard thing, and there will be some foreign body sensation when you wear them for the first time, but you can get used to it in about 2 days, as long as you ensure good personal hygiene and recheck on time, there is no harm.

It can effectively control the development of myopia, do not need to wear glasses during the day, is convenient for life, work and study, and the disadvantage is higher than that of ordinary glasses.

The pros outweigh the disadvantages, no need to wear glasses, convenient, and not increase the degree I have been fitted in Chongqing Preh Eye Hospital, and I have been wearing it for almost a year, and there is no discomfort in my eyes I have never had any keratitis.

Orthokeratology lenses originated in the United States, and after 50 years of development, they have been used in 34 countries around the world. It is a special inverse geometry designed orthokeratology lens with an inner surface consisting of multiple arcs. The uneven distribution of the lens and the tear layer, the resulting hydrodynamic effect changes the geometry of the cornea, and is worn on the front of the cornea while sleeping, gradually flattening the curvature of the cornea and shortening the eye axis, thus effectively preventing the development of myopia, and is known as "the technology that can control and correct myopia by sleeping".

Orthokeratology lenses**How do you get myopia? The main principle of orthokeratology lenses is that the patient wears a specially designed rigid gas permeable contact lens with a flat middle and a steep periphery, and the lens produces a slight compression on the cornea, thereby slowly changing the shape of the cornea, flattening the optical area of the cornea, thereby reducing myopia and astigmatism.

In the absence of effective methods to prevent and control myopia in adolescents, this technology does bring hope to both doctors and patients.

The ** of Medigo orthokeratology lenses is generally between 2800-10000, depending on the hospital, region, myopia degree, lens brand, material, design, **There are also differences. Recently, it was jointly organized by the Youth League Municipal Committee, the Municipal Youth Development Association, and the 254th Hospital of the People's Liberation Army. Apply for free trial for teenagers with myopia, in addition to the examination fee of 380 yuan, orthokeratology lenses are suitable for medical treatment.

As long as it is worn on the eyeball while sleeping, it will massage the eyeball flexibly, gradually make the corneal curvature change, flatten, and shorten the eye axis, thus effectively preventing the development of myopia, known as "the technology that can control and correct myopia while sleeping". It is designed with an inverse geometry with multiple arcs on the inner surface. The resulting fluid dynamics change the corneal geometry to correct myopia.

When I get up in the morning and take it off, my vision is back to its best, which is generally above.
