NO, the Ortho-K lenses are not suitable for everyone. The fitting rule is the same as lasik surgery except for corneal thickness. You have to be checked to see if you are a good candidate for it. You must have a healthy eye that is free of any corneal scarring and pathology.
Not everyone can be a candidate for orthokeratology. People who have something wrong with the cornea, like corneal scarring and other problems are not suitable for orthokeratology. So a candidate for orthokeratology should have healthy cornea.
Those people who have poor hygiene, severe dry eye, inflammations, infections and other problems are not a good candiate for Ortho-K lenses because they have no ability to handle the lens.So they are not suitable for Ortho-k.
Some people are not suitable for OrthoK. For example, people who have very high levels of myopia or those who are farsighted may not be qualified for Ortho-K lens. So I don't think everyone can be suitable for OrthoK treatment.
