The difference between corneal plastic mirror, RGP and myopia surgery!

Abstract: corneal shaping lens, also known as hard corneal contact 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. After

children are nearsighted, parents usually choose to wear frame glasses for their children, but do you know? In addition to frame glasses, you can also choose to wear corneal shaping glasses, RGP, and myopia surgery. Let’s look at the differences between them.

corneal shaping lens, also known as hard corneal contact 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.

after many parents arrive at the hospital, the doctor will recommend wearing corneal shaping glasses to control and alleviate the development of children’s myopia. Parents will also be distressed. Can keratoplasty really treat children’s myopia?

  1. Corneal shaping lens: effectively control the growth of myopia. Optometry experts of

and

point out that at present, the best way to control the development of juvenile myopia is corneal shaping lens. However, keratoplasty can not “cure” myopia, but delay the process of myopia as much as possible. When the child grows up, the degree of myopia is stable, Other methods (surgery) can be used to solve vision problems!

Corneal plastic lens is a non-surgical method to reduce diopter and improve naked eye vision by changing corneal morphology. The correction principle of corneal shaping lens is to gently shape the cornea with hard high permeability contact lenses, so as to flatten the central cornea of myopia patients, so as to reduce myopia and astigmatism and improve naked vision. After 8-10 hours of wearing corneal shaping glasses at night, the lens will slightly compress the cornea, slowly change the corneal shape and flatten the central optical area of the cornea, so as to effectively prevent the development of myopia. It is known as the “technology of controlling and correcting myopia by sleeping”. It does not wear any correction tools in the daytime and can maintain normal vision.

  2. What is the difference between corneal plastic 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.

  3. What is the difference between corneal plastic lens and excimer laser surgery? The principle of

and

corneal shaping lenses and excimer 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 by wearing lenses at night. This change is reversible. After stopping wearing corneal shaping lenses, the cornea completely recovers its original shape and state, Excimer 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, and the length of ocular axis is still changing. It is not suitable for excimer to treat myopia.
