I. What are keratoplasty lenses
Keratomileusis is a new type of youth myopia prevention and treatment means, it is through a physical shaping method, through a reasonable, programmed special design of rigid corneal shaping lens to achieve the role of reducing myopia, control the development of myopia. At night, it is worn on the surface of the eye, and then the cornea is deformed according to the reasonable shape we set, and through the change in the shape of the cornea, some of the problems that existed in the youth such as myopia and astigmatism can be specially and effectively corrected, so that the purpose of wearing the lens at night is to make the myopic cornea become mildly myopic or become non-myopic, and during the day, the youth, because of the change in the shape of the cornea, therefore myopia During the day, the shape of the cornea changes, so myopia is reduced or disappeared, long-term use can make myopia can be controlled (compared to the frame glasses control effect of more than 50%), but also can play a role in the prevention and treatment of myopia. At present, this is the latest research abroad, a new technology to treat and prevent myopia aggravation, especially for the control of youth myopia has a good role.
Second, what is the principle of keratoplasty lens
The optics of myopia is that the parallel incident light enters the eye and focuses on the front of the retina, i.e. the refractive power of the eye is too high. By wearing specially designed rigid orthopedic keratocontact lenses, the shape of the corneal surface can be reasonably altered to reduce the refractive power of the eye, thereby reducing or even eliminating myopia. This principle is the same as that of laser surgery. Except that laser surgery permanently chips away at some of the tissue inside the cornea, whereas keratoconus therapy works on the outer surface (epithelium) of the cornea and does not touch any of the internal corneal tissue.
Will keratomileusis have any side effects on the eyes?
Long-term use of keratomileusis will not cause particular adverse effects on the eye, but of course the premise of safety requires that it be worn under the premise of scientific and standardized use in accordance with the doctor’s prescription, and it can achieve a safe and effective effect. Therefore, the technology of keratoplasty to prevent myopia in adolescents is a safe and effective method.
Fourth, who is suitable for wearing rigid keratomileusis
1, children and adolescents using frame glasses do not have good results, myopia is growing rapidly
2, myopia, astigmatism, especially children with high refractive error
3, parents with high myopia, the child has a tendency to inherit
4, in the treatment of myopia in the optical lens it is the best quality is also the most advantageous.
V. Can students wear rigid keratomileusis?
At present, the treatment of keratoplasty is mainly for adolescent myopia, for example, at the age of about 8 years old, until about 18 years old, this age myopia is the fastest growing stage, some children may grow 100 degrees or even 200 degrees per year, such children are not given control will easily develop into high myopia. High myopia can have a negative impact on future studies and employment. Therefore, ophthalmologists advocate early control and early intervention for adolescent myopia. At present, there are many ways to prevent myopia in adolescents, but in general, international ophthalmologists generally recognize the method of myopia treatment with corneal shaping lenses.
Is it safe to wear rigid keratomileusis?
The premise of safe eyewear is that it must be used under the guidance of an ophthalmologist, and there is a scientific procedure for fitting and use in a regular hospital. Regularly go to the hospital to receive the optometrist’s review and maintenance, so that for children and adolescents, it is safer.
Seven, misconceptions: is it possible to cure myopia by wearing keratomileusis in the child stage
So far, there are many methods to prevent and treat myopia, but none of them can cure myopia at all. However, if used properly and in a timely manner, keratoplasty can have a significant effect on controlling and delaying the development of myopia in adolescents with long-term wear.
If the child wears the lenses for a period of time, the vision recovers well, and then stops wearing the lenses, the cornea may rebound back, resulting in a failure of myopia control, at which point it is necessary to insist on wearing the lenses to consolidate the effect.
Myopia that has already occurred cannot be eliminated by wearing keratoconus.
For children with increased myopia, the annual growth rate of myopia may be greater with ordinary frames, but the growth rate of myopia with keratomileusis is only about one-half of that with frames, or even less.
The clinical indicators show that keratoplasty is effective in delaying and controlling myopia.
Eight, the procedure of keratoconus care
First of all, it is very important to clean your hands and develop good hygiene habits. In addition, special care products must be used for the lenses. As the only children’s hospital in the province, our ophthalmology department is equipped with professional optometrists who are responsible for the supervision and implementation of this technology, and regularly perform all relevant examinations, lens cleaning and care for children with lenses.
Nine, about how long to wear rigid keratomileusis at night
Medium and low myopia should be worn for about 7-9 hours per night. High myopia, for example, more than 600 degrees, or even more than 1000 degrees, such children do not advocate the use of corneal plastic lens night wear, we recommend the use of RGP or corneal plastic lens day wear, so that not only can have a good vision effect during the day, but also will achieve a certain myopia control role, and safer.
