What is the role of orthokeratology?

summary

Orthokeratology originated in the United States. After 50 years of development, orthokeratology has been applied in 34 countries around the world; It is a special orthokeratology lens designed with inverse geometry, and its inner surface is composed of several arc segments. The lens and tear layer are unevenly distributed. The resulting hydrodynamic effect changes the geometry of the cornea. Wearing it on the front of the cornea during sleep gradually flattens the corneal curvature and shortens the axial length of the eye, thus effectively preventing the development of myopia. It is known as "the technology of controlling and correcting myopia when sleeping". What's the role of orthokeratology?

matters needing attention

Nowadays, the phenomenon of myopia among teenagers is more and more common. Most of the myopia is caused by careless use of eyes. Moreover, because young people are reluctant to wear frame glasses for fear of affecting their appearance, more and more people choose to wear orthokeratology glasses.
