First, it is not suitable for everyone. Orthokeratology is not recommended for patients with myopia over 600 degrees and children under 8 years old. Although orthokeratology can alleviate myopia for patients with high myopia and high astigmatism, it is difficult and risky for children under 8 years old to use it for fitting.

The effect of orthokeratology in controlling myopia gradually weakens with age. Orthokeratology is only effective in certain periods, such as childhood. Although orthokeratology can be used at different ages in the future, it is only to ensure the visual quality and not to wear glasses during the day.

Second, the economic cost is high and it needs to be replaced frequently. Orthokeratology is a breathable hard contact lens, which should be cleaned every day. During use, friction will leave scratches.

In the long run, the increase of scratches will lead to the decrease of lens oxygen permeability, protein deposition, corneal epithelial injury, pain and conjunctival congestion. Therefore, each lens will have a service life, and the recommended replacement period is one year.

Third, there are many illegal institutions, and glasses require that orthokeratology glasses are not ordinary glasses, but a non-surgical treatment. Some illegal organizations use orthokeratology as a means of profit, and counterfeit and shoddy products are also emerging in the market.

Therefore, medical accidents caused by orthokeratology are often reported by the media, and there have even been cases of retinal detachment caused by fitting orthokeratology lenses in illegal institutions.

Orthokeratology mirror, as the third kind of medical equipment, is very likely to cause corneal epithelial shedding and even inflammatory reaction of corneal infection if it is not properly worn. Therefore, there should be strict requirements for the qualifications of the wearer and the facilities of the wearing unit. ?
