Can corneal plastic lens really control the growth of myopia?

Abstract: the fitting age of corneal plastic lens is generally older than 8 years old. Children with myopia can slow down the development of myopia by wearing corneal shaping glasses; Adults wearing corneal shaping glasses can improve daytime vision and quality of life.

what is a keratoscope?

corneal shaping lens, also known as “O.K lens”, is a kind of “contact lens”, but it is not what we usually call “contact lens”, because of its special material and design, it can be worn during sleep at night and control the development of myopia.

can wearing corneal shaping glasses really control the development of myopia?

corneal shaping lens has its unique anti geometric design. The radian of the central area of the lens is smoother than that of the central area of the individual cornea. Wearing at night can flatten the center of the cornea and reduce or even eliminate myopia. However, because the corneal tissue is elastic, the effect of reducing myopia is reversible, Therefore, the main function of corneal plastic lens is to control the progress of myopia. How old can

and

wear corneal shaping glasses? The fitting age of

and

corneal plastic lenses is generally greater than 8 years old. Children with myopia can slow down the development of myopia by wearing corneal shaping glasses; Adults wearing corneal shaping glasses can improve daytime vision and quality of life. What is the role of

and

corneal shaping lenses in controlling myopia? Due to its unique multi arc design, the central area of the

and

corneal shaping lenses is flat compared with the central area of the cornea. When worn at night, the optical characteristics of the inner front surface of the cornea are changed through the force of tears between them, so as to temporarily reduce myopia and astigmatism. Compared with frame glasses, corneal shaping lens can not only correct the refractive state of macula, but also correct the refractive state of peripheral retina, and effectively slow down the development of myopia. What is the difference between

corneal shaping lens and RGP?

and

corneal shaping lenses and RGP belong to breathable rigid corneal contact lenses. Corneal shaping lenses are mainly worn at night and RGP is mainly worn daily. The main function of corneal shaping lens is to control and slow down the development of myopia. Wearing it at night can achieve better naked vision during the day and take off the shackles of frame glasses. RGP can achieve clear vision when worn during the day. The two are suitable for different groups of people.

what degree of myopia is suitable for people to wear corneal shaping glasses?

and

corneal shaping lenses are suitable for people with myopia below 600 degrees, astigmatism within 150 degrees, no organic lesions in both eyes, and the degree increases too fast. What is the difference between

corneal plastic lens and laser surgery? The principle of

and

corneal shaping lenses and laser surgery in the treatment of myopia is to change the optical characteristics of the central anterior surface of the cornea, but the corneal shaping lens flattens the central area of the cornea through tears through the elastic action of corneal tissue through wearing lenses at night. This change is reversible. After stopping wearing corneal shaping lenses, the cornea completely recovers its original shape and state, Laser surgery is to thin the central part of the cornea, which is permanent and irreversible. For teenagers, the degree of myopia is not stable, the length of eye axis is still changing, and it is not suitable for laser surgery to treat myopia. After adulthood, and the degree of myopia is stable for two years, it is more suitable for laser surgery to treat myopia.

which kind of corneal shaping lens is more recommended by doctors? The designs of

and

corneal shaping lenses are divided into: VST design (vision shaping treatment) is the design patent of Boston company in the United States; CRT design Corneal refractive therapy is a design patent of Paragon company of the United States. At present, Paragon CRT of the United States, alpha of Japan, Euclidean of the United States, e-anyi of Hong Kong, luxid of Korea, Hengtai of Taiwan and David of China dream are used in China. Paragon crt100 of Paragon company and David of China dream are the most popular among doctors Recommended.
