OK镜副作用了解一下：网页链接 Ortho-k is associated with an increased risk of infection (microbial/bacterial keratitis). This risk is especially concerning for children and adolescents, who may be less able than adults to maintain good hand and contact lens hygiene.
Each year, nearly a million Americans go to the doctor because of eye infections. And the biggest risk factor for infections is contact lens wear. Eye infections can have serious consequences including lifelong vision impairment. For this reason, ortho-k may be more dangerous than glasses, which can be used to correct the same conditions. That’s one of the reasons it is important to consult with an ophthalmologist if you are considering ortho-k.
There is no limit to how long you can use orthokeratology lenses. You must see your ophthalmologist for regular check-ups. But if your eyes stay healthy and comfortable, ortho-k could be used for years.
