Popular Science | Answers to common questions about orthokeratology lenses

Recently, many parents and friends have come to offline science museums to consult about issues related to orthokeratology lenses, so let’s have a concentrated answer today!

1. Can I wear orthokeratology lenses if I have inverted eyelashes?

Whether or not a child with ingrown eyelashes can wear orthokeratology lenses depends on the extent of the child's ingrown eyelashes. If the child's ingrown eyelashes are mild, with only a few eyelashes touching the eyeball, there is a chance that orthokeratology lenses can be worn.

If the trichiasis is very serious and a row of eyelashes poke the cornea, the child will cry at any time. In this case, the trichiasis needs to be treated first.

There are two ways to deal with inverted eyelashes: one is non-surgical measures, including using inverted eyelash stickers and eyelash curlers; the other is surgery. You should listen to the advice of professional doctors for details.

2. Can I wear orthokeratology lenses when I have a cold?

Colds are mostly caused by viral infections. During a cold, the human body will carry more viruses and germs. Wearing glasses during this period will increase the probability of eye infection.

During a cold, the body's resistance and immunity will be significantly reduced, and the body's ability to resist external germs and viruses will be reduced. If the lenses are not cleaned properly, it may also cause eye inflammation.

Most people will take cold medicine during a cold, and the medicine may affect tear secretion, resulting in poor tear quality and quantity. Continuing to wear glasses during this period is relatively more likely to cause eye discomfort.

Therefore, regardless of the severity of the cold, we recommend that the wearer stop wearing it for prevention and safety reasons.

3. If my child likes to sleep on his stomach, can he wear orthokeratology lenses?

When wearing OK lenses for the first time, you should sleep lying flat as much as possible. After wearing them for a day or two, the shaping will be basically stable. Even if the child does not sleep well later, it will not have a big impact.

4. Will my myopia degree stop increasing after wearing orthokeratology lenses?

After wearing orthokeratology lenses, the overall control rate reported in the literature is about 50%, but the control effect varies greatly. First of all, it is due to individual differences. Each child's age, myopia degree, genetic condition, eye habits, and eye condition are different. For some children, myopia increases very slowly after wearing orthokeratology lenses, but for some children, it still progresses rapidly. This is the embodiment of individual differences.

Generally speaking, children with large pupils, high myopia, and steep corneas will have better control effects, and vice versa. Therefore, it does not mean that the degree of myopia will not increase after wearing orthokeratology lenses. Slowing down the growth rate of myopia requires the combined control of multiple means.

5.Which brand of orthokeratology lenses is more effective?

There are many brands of orthokeratology lenses, but there is no definite conclusion on which brand is better. Because different children have different corneal morphologies, some children may be more picky about lenses and only fit certain brands; some children have ordinary corneal morphologies and can choose from all brands.

When choosing suitable OK glasses for children, we also need to consider the growth rate of children's myopia and the vision requirements during the day. We need to consider them as appropriate and comprehensively consider the children's eye conditions, daily habits, and eye needs before we can choose the most suitable lenses for children.

At present, we have access to many products related to the prevention and control of myopia in children, but the prevention and control of myopia in children cannot rely on just one product or one method. To effectively control myopia in children, an effective plan that includes behavioral habits, drug means and optical means is needed, and it can be persisted for a long time.
