Before the age of thirteen, it is an important stage and period for children's vision and vision development.
After parents find that their child's vision has decreased, they must take their child to the hospital for mydriatic refraction, and after the examination is clear that it is true myopia, then treatment measures should be taken.
Many parents will ask, is it better to wear glasses or orthokeratology lenses for children's myopia?
Let's talk about the advantages and disadvantages of glasses and orthokeratology lenses.
Children with myopia wear glasses
What are the advantages?
What to pay attention to?
It is generally recommended to wear glasses after myopia in children, and the acceptance of glasses is relatively high, especially for younger children.
In addition, the child is in the stage of vision development, with the development of the eyeball, the degree of myopia will develop relatively quickly, the lens update will be very frequent, the advantage of glasses is that it can be replaced at any time.
It is important for parents to choose lenses and frames for their children.
First of all, the quality of the lens should be good, and the power should be appropriate. Choosing the right lens power must be done for medical refraction, that is, mydriatic refraction, and atropine is generally used for mydriasis before the age of thirteen. Atropine is a slow mydriatic drug, so that the ciliary muscle of the eye is fully paralyzed and rested, and the measured prescription is accurate.
Choose a frame, don't just look at whether the appearance is good or not, wear it must be the right interpupillary distance, interpupillary distance is the distance between the pupils of both eyes, everyone's pupil distance is different.
Generally, before the age of thirteen, you must go to the hospital once a year or half a year to check once, measure the interpupillary distance, refraction, see if the degree of myopia has increased, whether the interpupillary distance has changed, and replace the glasses in time if there is a change.
Some parents see that their children's myopia degree has increased, so they only change the lenses for their children, not the frames, which is not right.
Because as we age, the interpupillary distance changes after the face develops. Some parents see that the degree of myopia of their children is not long, so they have not changed their glasses, and the lenses can not be changed, but the frames should be replaced in time according to the change of interpupillary distance.
In addition, glasses should be worn every day, do not take them off for a while, affect the adjustment of the eyes, in addition to sleeping and not wearing, you should insist on wearing them during the day, especially those with high myopia.
Children with myopia wear orthokeratology lenses
Sometimes children play outside, wearing glasses is not very convenient, it is easy to break the glasses during play, the lenses may prick the eyes or hurt the child, which is also the most worried problem for parents.
Therefore, there are also many parents who will choose orthokeratology lenses for their children, especially for active children, orthokeratology lenses are also a good choice.
Orthokeratology lenses are generally suitable for children with low myopia, that is, myopia below 400 degrees, and the effect below 300 degrees will be better.
Orthokeratology lenses are also tailored to the condition of the eyes, choosing the appropriate degree and curvature.
The most important function of orthokeratology lenses is to delay the speed of myopia development, because orthokeratology lenses are directly attached to the eyeball, just like playing abdominal belt, there is some inhibition of the development rate of the eyeball, myopia will develop more slowly, can play a role in preventing and controlling myopia, but not absolute, usually pay attention to eye hygiene.
Orthokeratology lenses are generally worn at night, and the advantage of wearing them at night is that they are not easy to infect, because the eyes are closed when sleeping, and there is no contact with the outside world.
At night, wash your hands before going to bed and put them on your child, just like wearing contact lenses, wear them overnight, and then take them off in the morning.
For example, the child's visual acuity is 0.1, after wearing plastic glasses overnight, the daytime vision can reach 1.0 the next day, can have a very good naked eye vision, no need to wear glasses during the day, life is more convenient.
Orthokeratology lenses can generally only be worn for one day overnight, the vast majority of people, especially people with high degrees do not wear them the next day, and their vision returns to the previous level, so they have to wear them every night, generally children over six or seven years old wear a lot, too young children can not cooperate, can not wear.
At present, for children, correcting myopia is mainly glasses and orthokeratology lenses, parents can choose for their children according to the specific situation, each has its own advantages and disadvantages.
Many parents ask, in addition to wearing mirrors, are there any drugs that can treat myopia in children?
Until now, there has not been a single drug in the world that can treat myopia. If the child is relatively young, close-up reading time is relatively long, easy to appear eye fatigue, you can use atropine to dilate the pupils, let the eyes rest, can slow down the development of myopia, but there is no real treatment of myopia drugs.
Everyone also knows that myopia can also be corrected by surgery, so how old can a child be for myopia surgery?
At what age can my child's myopia be corrected by surgery?
Because surgical correction of myopia is a one-time molding, it is recommended to do it over 18 years old, because 18 years old is an adult, and the body is basically stable.
Surgical correction of myopia mainly uses lasers, there are two kinds of lasers, one is excimer laser, accurate molecular level cutting of the cornea; One is a femtosecond laser, which is fast laser cutting.
Surgery can be done with all excimer laser, can also be excimer combined with femtosecond laser to do, can also be full femtosecond laser to do, these three types of surgery is currently the market share is relatively high, the specific choice, according to personal conditions and myopia degree to decide.
