Myopia has become the most prevalent eye disease in the world today. Nearly one-third of the people in China, which accounts for one-fourth of the world’s population, suffer from myopia, especially among teenagers who are burdened with heavy school work.
Myopia can cause a loss of distance vision in the naked eye, causing many inconveniences in work, study and life, and limiting the chance of further education and employment. High myopia, especially super high myopia, not only causes loss of distance vision, but its complications can often cause serious visual impairment and cannot be corrected, even if refractive surgery is difficult to achieve satisfactory results. Therefore, it is important to control the development of myopia in adolescence.
Other methods of myopia correction.
1, frame glasses: cannot provide better quality of vision, many inconveniences in life and sports, and poor appearance.
2, soft corneal contact lenses (soft contact lenses): blocking the corneal supply pathway is a higher risk of infection in the oxygen-deprived cornea, and cannot control the development of myopia.
3, refractive surgery: requires myopia stability for more than 2 years, age 18 years or older, many surgical methods but some patients will not be able to implement the surgery because the myopia is too large.
Keratomileusis.
Keratomileusis and RGP can effectively control and slow down the development of myopia. Keratomileusis is a reversible, non-surgical method of reducing myopia and improving naked eye vision by gradually flattening the central area of the cornea and reducing corneal refractive power through corneal shaping.
I. Features of keratomileusis.
1. a special type of contact lens.
2, used for the correction of low to moderate myopia.
3. nighttime wear.
4.Improve daytime naked eye vision.
5, reversible, can not cure myopia.
6.Effectively control and delay the development of myopia in adolescents.
Second, the indications for keratomileusis.
1, low to moderate myopia: lens maximum – 6.00D, myopia 0.75 – 5.00D.
2, astigmatism ≤ 2.00D.
3, progressive myopia in children and adolescents, delaying the development of myopia.
Third, the corneal shaping lens for the population.
1, adolescents with progressive myopia aged 8 years or older, can cooperate with the examination and removal.
2, adults who wish to solve myopia problems through non-surgical methods. Such as medical examinations, athletes, police officers, etc.
3, myopia, astigmatism within the capacity of keratoconus.
4, corneal curvature between 40-46.
5, no active inflammation of the cornea and no other eye disorders that are not suitable for contact lenses.
6, good hygiene conditions, good compliance.
Rigid oxygen permeable contact lens (RGP)
It is a kind of high oxygen permeable contact lens. It is currently the latest international popular contact lens, is an important symbol of the development of optometric disciplines. It is made of a special material that has good oxygen permeability and unique optical properties, thus reducing aberrations, improving retinal imaging quality, significantly improving visual correction and reducing the occurrence of complications. RGP is ideal for patients with special refractive errors, such as high astigmatism and cone corneas, who cannot achieve good correction results with ordinary frames and soft lenses. RGP is the ideal choice. And it has excellent clinical effect on controlling the development of myopia in adolescents.
I. Characteristics of RGP.
1.Highly oxygen permeable and safe contact lenses.
2.Good optical performance to give you better visual results and correct high astigmatism and irregular astigmatism.
3, comprehensive examination by clinicians, according to the examination data tailored to give the most accurate, the most scientific correction.
4.Simple to use, easy to care for and long life.
5. It can delay the rapid development of myopia in adolescents, and is the most ideal vision correction choice for adolescents.
Second, RGP is suitable for people.
1.Patients with myopia and farsightedness within 2000 degrees.
2, astigmatism including irregular astigmatism and high astigmatism.
3, refractive parallax.
4.Cone cornea.
5, aphakic eyes.
