What are the hazards of orthokeratology lenses

Orthokeratology lenses are a device used to correct vision. Many people need to use them, but they also have their hazards. For example, for people with some special corneal diseases, the choice of orthokeratology lenses should be more stringent to avoid inflammation.

1. Orthokeratology lenses are designed for myopic patients with keratoconus and other myopic patients with special corneal diseases.

If this statement is a question to an experienced ophthalmologist, it is clear that orthokeratology and RGP are confused. Although both are rigid contact lenses, their uses are completely different. Orthokeratology lenses are mainly used for children with myopia within 600 degrees. If they meet the requirements after examination, they can effectively control the progression of myopia and improve naked eye vision. RGP is mainly used for patients with high myopia above 600 and keratoconus. It is obvious that the post refers to RGP, not orthokeratology lenses.

2. Both the U.S. FDA and China's National Drug Control Administration stipulate that orthokeratology lenses are Class III medical devices. The third category of medical devices is dangerous

The highest level of medical equipment. How can such a medical device with the highest risk level (orthokeratology lens) be used for common myopia in children and adolescents? There is no age limit for the applicable population of orthokeratology lens. The main test rate is on the child's hands-on ability, and the general requirement is 8-40 years old.

3. If you are not careful, orthokeratology lenses can cause corneal inflammation, perforation, and blindness.

Therefore, many of the adverse reactions to wearing orthokeratology lenses that are now flooding the Internet occurred at that stage rather than at the current stage. Currently, orthokeratology lenses have developed to the latest fourth generation product. There are very few reports in the media about serious adverse events caused by wearing orthokeratology lenses.
