What is the experience of using orthokeratology lens?

The inner surface of the orthokeratology mirror is parallel to the corneal surface and coincides with each other. The brightness of the lens can be adjusted by changing the outer surface of the lens. Plastic mirrors used for "orthopedic" are the opposite. Its outer surface is simple and its inner surface is relatively complex.

The inner surface of the plastic mirror is no longer parallel or consistent with the cornea, but creates some gaps between the lens and the cornea, and achieves the "orthopedic" effect by using the role of tears.

Extended data:

Although orthokeratology has delayed the development of myopia to a certain extent, it still has limitations and cannot solve all myopia problems. Wearing orthokeratology lens can't completely cure myopia, but it can only be worn at night to relieve vision, and it must be worn when sleeping every night to ensure the pressure brought by the lens to the eyeball. If you don't insist on wearing it and continue to put pressure on the outside of the cornea, your vision will soon rebound and return to its original vision.

Eye examination before wearing orthokeratology lens is very important. Only suitable physiological conditions can ensure the safety and effectiveness of wearing orthokeratology lens. Eye examination includes ocular surface analysis, axial length, corneal thickness and intraocular pressure. Wearing plastic glasses can improve mild and moderate myopia within 600 degrees within a certain range. However, for patients with high myopia above 600 degrees, the wearing effect is not ideal.
