Does long-term wearing of orthokeratology lenses have any effect on the cornea?

There are more and more children with myopia, and orthokeratology lenses are becoming more and more popular among parents. Because orthokeratology lenses are special and are worn at night when sleeping and on the surface of the eyeball, many parents always have some doubts and concerns about safety issues.

Orthokeratology lenses have the effect of slowing down the progression of myopia, which is determined by the principle of the lens. Orthokeratology lenses are worn at night when sleeping. When worn, the lens will form a downward pressure in the center of the cornea, and then under the action of this pressure, the tears will form a "pulling force" on both sides through fluid mechanics. Under the action of pressure and tension, the corneal morphology will be temporarily reshaped, so that you can see clearly without wearing glasses during the day, bringing the effect of slowing down the progression of myopia. To achieve good myopia prevention and control effects, it is essential to follow the doctor's advice to wear the glasses scientifically and establish good eye habits.

Will it cause damage to the eyes? Will it affect the future development of the eyes?

I just talked about the principle of orthokeratology. Orthokeratology does not actually increase the risk of corneal infection. Most of the adverse reactions in clinical practice are caused by improper wearing and care, so it is important to pay attention to correct wearing and care, which can reduce the risk of eye infection. However, it is also reminded that if children experience eye pain, red eyes, photophobia, tears, etc. after wearing glasses, they must stop wearing them immediately and go to the hospital for a follow-up visit in time, so that the doctor can make the correct judgment and treatment.

In summary, if you want to wear orthokeratology lenses scientifically, you need to meet these three conditions:

① Accurate fitting: Orthokeratology lenses are classified as Class III medical devices and require personalized fitting at a professional ophthalmology hospital or optometry clinic with the help of professional physicians;

② Regular follow-up: After fitting the lenses, you need to follow the doctor's advice and go to the hospital for regular follow-up;

③ Standardized care: The infection problems reported so far are caused by improper care, so you should follow the doctor's advice and follow the standardized care. For example, you should rub and clean your glasses before and after wearing them every day, and perform protein removal care once a week.

So what should we pay attention to when choosing OK lens care solution?

He Yongchuan, deputy director of Chongqing Aier Children's Eye Hospital, said: When choosing a care solution, we must first pay attention to the disinfection effect. If the disinfection effect is not good or thorough, it will affect the safety of wearing glasses, and the lenses will become uncomfortable to wear over time. Therefore, the disinfection effect is the most critical.

The second is the ingredients. Nowadays, people pay much attention to the ingredients of the food and things they use. We should also pay attention to the ingredients when choosing the care solution. Because OK lenses are worn directly into the eyes, the care solution will have residues on the lenses, so the ingredients of the care solution must be mild and should not cause irritation or discomfort to the eyes.

Another thing is that the operation is simple. Sometimes there are too many bottles and jars of care products, and it is easy for both parents and children to make mistakes during the operation. Especially for some children who live in school, it is easy for children to make mistakes in too complicated care processes. Once used incorrectly, the consequences can be very serious. Therefore, the simpler the care, the better.

Finally, it can deal with emergencies and achieve disinfection effects in a short time.
