The first time the school year started, some parents found their children had myopia problems, they heard that the OK mirror on the market can correct children’s vision, but about OK mirror can wear, but there are many different opinions.
The following, my own personal experience to introduce you to the full range of the OK mirror is right and wrong. OK mirror is a good thing, but the fitting is really a lot of things.
When I got the school physical, my heart thumped: my son’s bilateral bare eye vision was 4.6!
I found out before that he was holding things very close, saying that the blackboard words are sometimes hard to read, but a month ago there was 4.8, fell really fast ah! But think about us as a couple, each of us has more than 500 degrees of nearsightedness, plus the child is really good at reading and using his eyes for homework, so it’s not surprising that it’s falling fast. But as a child in Primary 2 to Primary 3, such progress, that’s not good!
So I rushed to take my child to a professional eye doctor, who used atropine to dilate his pupils and then conducted a medical optometry, and patiently explained, “Only when the ‘ciliary muscle’ that controls the adjustment is paralyzed can the exact prescription be determined, because the child’s adjustment ability is so strong that an optometry without dilating the pupils is not completely accurate.
My son loves swimming and basketball, so I didn’t give him any frames because of this concern. One time at dinner, a friend mentioned that his child had been wearing OK lenses for over a year and everything was going well. The point is, the father proudly told me: they play together three children, the remaining two degrees of progress far faster than his son, and now those two children are also ready to come to the glasses.
But I also knew that not every child is suitable for OK lenses, and that an evaluation would be done before wearing them. So, I started to learn more about OK lenses.
First experience with OK lenses
OK lenses are called “keratomileusis”, and they are used to correct vision by changing the curvature of the cornea. You can wear them in bed and take them in the morning to ensure your vision during the day.
After my son underwent a professional eye examination and optometry, the doctor conducted another related examination on the cornea. The results came back and my son was a perfect fit for OK lenses! The doctor immediately determined the prescription of the OK lenses and helped us with the first trial fitting. My son adapted quite well to the first fitting, and his eye irritation was fine, and he proudly asked me to point out his vision chart to him. He tried it on for 40 minutes and his vision actually went up to 5.1.
The next biggest problem was the parents assisting in wearing the glasses. At first I was very confident because I had a lot of experience wearing contact lenses for more than 10 years, and when I saw the lenses, I thought I could totally put them on my son by myself. But after I watched the doctor’s demonstration once, I realized: old revolution meets new problem.
Second, the use of OK lenses
1, take and put need to be careful
OK lens lens texture and contact lenses are completely different, thick texture, and seems to be very brittle, pinching process should really be careful;.
2, cleaning strength appropriate
Protein removal process is complex, especially the scrubbing process, the force is appropriate to effectively remove protein, too hard, the lens may be directly crushed;.
3, cleaning with cold water
Rinse the lenses but also prepare cold boiling water, pure water at home is not recommended.
4, take the mirror skills
Take the lens, relying on a small stick, must be firmly attached to the corneal lens, and then a suction, before coming down.
My son called me on the first morning of wearing it well: “Mom, I can now see the license plate number of every car driving by! When I heard this, I thought about what is a few more minutes a day for “24 mothers” like us. What’s more important is to face the annoying matter of “myopia” together with our children, so that they can cherish the clear world now.
We went to the hospital for a follow-up visit in the first three weeks of wearing the lenses, and the doctor carefully examined my son’s cornea and observed the process of wearing the lenses on my child, pointing out the shortcomings. In the future, monthly checkups were necessary, and after six months, semi-annually.
However, OK lenses do not “cure” myopia, they only slow down the process as much as possible. When the child grows up and the myopia stabilizes, other methods (such as surgery) can be used to solve the vision problem!
Third, learn more about OK lenses
Orthokeratology is a reversible physical correction method that changes the shape of the cornea by wearing a specially designed contact lens that is both rigid and gas permeable, thereby reducing myopia and improving naked eye vision.
A number of studies at home and abroad have shown that OK lenses can effectively curb the progression of myopia in adolescents.
OK lenses are flat in the center and steep in the middle and periphery, which accelerates the shaping speed and makes the effect stable and continuous. Through the hydrodynamic action of tears, the cornea and the lens are drawn tighter and tighter, completing the shaping of the cornea. The lenses are made of high oxygen permeable material to ensure safe night wear.
Who can wear OK lenses?
OK lenses are useful for slowing down the progression of myopia, and young people with myopia are the main group of people using OK lenses in China, but the effect of control varies from person to person.
OK lenses are suitable for myopic patients who do not want to wear frames or whose occupation requires that they cannot wear regular contact lenses.
Specific fitting requirements: age 9 or older, simple myopia or myopic astigmatism, the most ideal degree is less than 450 degrees of myopia, parsimonious astigmatism less than 150 degrees, beyond the above degree fitting difficulty will increase. In addition, the corneal topography of the corneal curvature, corneal eccentricity index and corneal transverse diameter and other parameters also have certain requirements.
V. Who cannot wear OK lenses?
Similar to other corneal contact lenses, OK lenses are not suitable for the following people.
1, various active inflammatory diseases of the anterior segment of the eye.
2, untreated allergic conjunctivitis.
3, severe dry eyes.
4, blepharoplasty gland dysfunction.
5, history of contact lens or contact lens care solution allergy, etc.
In summary, normal ocular surface physiology is required for the fitting of corneal contact lenses. For children, compliance and initiative also need to be considered before fitting, such as whether they live or walk in school, whether they are very sensitive, hygienic and self-disciplined, etc., which may affect the long-term safety and effectiveness.
Therefore, although OK lenses are good for adolescents, fitting them requires a combination of multiple factors. There are two sides to everything, and the same is true for OK lenses.
Its advantages are.
It can delay the deepening of myopia.
You don’t have to wear glasses during the day.
The disadvantages are
Expensive.
require more time and effort from parents to pay attention to the use and cleaning of their child’s lenses.
seven. there is a risk of causing inflammation of the cornea.
If you want to wear OK lenses, you must go to a regular hospital and follow strict medical advice during use, regular cleaning of the lenses as well as regular review. Both parents and children should always keep in mind that eye hygiene is the most important.
