Keratoplasty is an effective reversible treatment for non-surgical removal of myopia through the use of specially designed keratoplasty lenses that symmetrically and progressively change the shape of the central corneal surface; similar to laser surgery, but unlike laser surgery, keratoplasty produces temporary and reversible results.
I. What is keratoplasty?
It is a type of corneal contact lens made of rigid, highly oxygen-permeable and light-transmitting material that reshapes the curvature of the cornea by changing the curvature of the cornea to reduce myopia and astigmatism, thereby improving vision or achieving normal vision.
Second, what diseases can be treated with keratomileusis?
1.Light and moderate myopia
2, astigmatism
3, teenage eyes are still in the developmental stage, especially sensitive to the role of shaping, so corneal shaping contact lenses are particularly suitable for teenagers, can be described as the ideal method of treatment to prevent myopia in adolescents, while the treatment method is simple, fast results.
Third, what is the difference between corneal film shaping lenses and ordinary contact lenses?
1.Different materials
Made of high oxygen permeability and high light transmission American special aerospace materials.
2, different wearing methods
Corneal membrane shaping lens is mostly night wear type. But if myopia is very high, you can wear at night with part of the day to meet the daytime refractive requirements, to be more stable corneal shaping, can gradually reduce the wearing time.
3.Different designs
There are four different curved surfaces on the inner surface of OK lenses, which play different roles in keratomileusis and coordinate with each other to eventually change the corneal refractive power and improve the refractive state.
Four, the characteristics of the corneal membrane shaping lens
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 shaping is particularly sensitive, so the corneal plastic contact lenses are 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 to 7 days effect.
3.Keratomileusis contact lenses are also suitable for the treatment of myopia in various age groups, with a wide range of applications.
4, corneal plastic contact 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 activities of the corneal epithelium, compared with ordinary contact lenses, can reduce the incidence of complications.
V. Wearing method.
As the current corneal film shaping lens is made of high oxygen permeable material, it can meet the corneal oxygen requirement for night wear, so the corneal film shaping lens is mostly night wear type. However, if the myopia is very high, you can wear them at night with some day wear to meet the daytime refractive requirements. After the corneal shaping is more stable, the wearing time can be gradually reduced.
Six, what are the complications of keratoplasty?
1, transient astigmatism
2, corneal damage, such as eye discomfort, eye grinding, eye redness, need to promptly go to the hospital.
