I. What is OK lens?
It is a kind of corneal contact lens made of rigid high oxygen permeable and high light transmitting material, which reshapes the curvature of the cornea by changing the curvature of the cornea to reduce myopia and astigmatism, thus improving vision or achieving normal vision.
Second, OK lens can treat which diseases?
1.Light and moderate myopia
2, astigmatism
3, adolescent eye is still in the developmental period, the role of plastic is particularly sensitive, so the keratoplasty contact lens (OK lens) is particularly suitable for adolescents, can be described as the ideal method of treatment to prevent myopia in adolescents, while the treatment method is simple, fast results.
What is the difference between OK lenses and ordinary contact lenses?
1, the material is different, using high oxygen permeability and high light transmission rate of the United States special aerospace materials made.
2, wearing different ways, OK lenses are mostly night wear type. But if myopia is very high, you can wear them at night with some day wear to meet the daytime refractive requirements. To be more stable corneal shaping, you can gradually reduce the wearing time.
3, different design, OK lens inner surface has four different curved surface, in the corneal plastic play different roles, coordinate with each other eventually change the corneal refractive power, improve the refractive state.
Fourth, the characteristics of OK lenses
1, keratomileusis contact lens is a non-surgical treatment method, will not cause any pain and inconvenience to patients, even if the refractive correction is not satisfactory, will not damage the cornea.
2, adolescent eye is still in the developmental stage, the role of the plastic is particularly sensitive, so the corneal plastic contact lens (OK lens) is particularly suitable for adolescents, while the treatment method is simple, fast results. According to statistics, moderate, low myopia, after 3 months of wearing, correction rate of 95% or more, the fastest 3-7 days effect.
3.Keratomileusis contact lenses (OK lenses) are also suitable for the treatment of myopia in various age groups, with a wide range of applications.
4, corneal shaping contact lenses (OK lenses) are mostly night wear type, can effectively avoid external pollution, impact, no need to wear during the day, the naked eye can still maintain normal vision, wearing safety. High oxygen permeable materials ensure normal physiological activity of the corneal epithelium, compared with ordinary contact lenses, can reduce the incidence of complications.
V. Wearing method.
As the current OK lens is made of high oxygen permeable material, it can meet the corneal oxygen requirement for night wear, so OK lens is mostly night wear type. But if myopia is very high, you can wear night wear with part of the day wear, to meet the daytime refractive requirements. After the corneal plasticization is more stable, you can gradually reduce the wearing time.
Six, what are the complications of OK lenses?
1, transient astigmatism
2, corneal damage, such as eye discomfort, eye grinding, eye red, need to go to the hospital in a timely manner.
