Abstract: at present, the popular rigid high oxygen permeability contact lenses (RGP) not only improve the oxygen permeability, but also ensure good wettability and anti precipitation. It can correct myopia within 2200 degrees and astigmatism within 600 degrees; The chance of causing corneal infection is small and the safety is high., With the popularization of electronic products, the aggravation of learning burden and the shortening of outdoor time, myopia or other refractive errors (including hyperopia and astigmatism) have become the most common eye diseases. Once ametropia occurs, it can be corrected in many ways, and the choice of which method still varies from person to person., Wear glasses according to the doctor’s advice. There are a wide variety of glasses, including simple frame glasses, more convenient contact lenses for wearing in the eyes, and corneal shaping glasses that can alleviate the deepening of juvenile myopia. How to choose glasses? Experts made in-depth analysis: firstly, it is convenient to select frame glasses for fitting, with low one-time cost, but it is inconvenient to live and exercise. If the fitting is not professional, wearing them for a long time will lead to eye deformation. Secondly, compared with frame glasses, soft contact lenses have less visual deformation and wider visual field, but the correction range is limited and the astigmatism correction effect is poor. Long term wearing may lead to complications such as corneal edema and dry eye. Improper wearing methods will lead to corneal and conjunctival inflammation., At present, the popular rigid high oxygen permeability contact lenses (RGP) not only improve the oxygen permeability, but also ensure good wettability and anti precipitation. It can correct myopia within 2200 degrees and astigmatism within 600 degrees; The chance of causing corneal infection is small and the safety is high. However, during the use process, attention should be paid to the care of lenses and eyes, and the wearing should follow the doctor’s advice., There is also a corneal shaping lens suitable for teenagers and children. This is a contact lens with high oxygen permeability and shaping function. It can gently reshape the corneal epidermis. It only needs to be worn when sleeping at night and clear vision can be obtained without wearing glasses during the day. Wearing it for a long time can effectively reduce the deepening of juvenile myopia., The effect of laser myopia surgery is good. After more than 20 years of development, myopia surgery has reached a very high level. It is generally suitable for those over 18 years old whose myopia is stable and no longer deepened. Laser surgery has a wide range of myopia correction, which can reduce the degree of myopia at one time, and avoid the inconvenience of wearing frame glasses or contact lenses and nursing work.,

glasses should be worn according to the doctor’s advice. There are a wide variety of

glasses, including simple frame glasses, more convenient contact lenses for wearing in the eyes, and corneal shaping glasses that can alleviate the deepening of juvenile myopia. How to choose glasses? Expert in-depth analysis:
first of all, the selection of frame glasses is convenient for fitting, with low one-time cost, but it is inconvenient for life and movement. If the fitting is not professional, wearing it for a long time will lead to eye deformation. Secondly, compared with frame glasses, soft contact lenses have less visual deformation and wider visual field, but the correction range is limited and the astigmatism correction effect is poor. Long term wearing may lead to complications such as corneal edema and dry eye. Improper wearing methods will lead to corneal and conjunctival inflammation.

laser myopia surgery has achieved good results.
myopia surgery has reached a very high level after more than 20 years of development. It is generally suitable for those over 18 years old whose myopia is stable and no longer deepened. Laser surgery has a wide range of myopia correction, which can reduce the degree of myopia at one time, and avoid the inconvenience of wearing frame glasses or contact lenses and nursing work.
and
ophthalmologists summarized the following three common surgical methods:
and
the first is ordinary LASIK surgery, which uses a micro corneal lamellar knife to make a corneal flap in the corneal stroma, and then uses excimer laser for treatment, so as to achieve the purpose of correcting ametropia. Although the operation time is short, the postoperative response is good and the price is relatively cheap, it is not suitable for patients with too high degree. The second kind of
and
is femtosecond laser LASIK surgery. Femtosecond laser is used instead of mechanical lamellar knife to make corneal flap, and then excimer laser is used for treatment, so as to achieve the purpose of correcting ametropia, increase the safety and predictability of surgery and greatly reduce the risk of surgery. The disadvantage is that the cost is relatively high and the requirements for machines and operators are higher.
the third is all femtosecond laser myopia surgery. All femtosecond laser myopia surgery is the most advanced corneal refractive surgery in the world, without making corneal flap. When correcting ametropia, laser does not need a knife at all. It can make use of its characteristics of high precision, high power and high resolution to decompose and expand the cells between corneal layers with the same thickness to make a uniform corneal flap. The cost of this kind of operation is relatively high, and it is not suitable for patients above -10.00d.
