I heard that Ortho-K lenses are good for eyes. Is that true? What are advantages of Ortho-K lenses?

[Clyattville]

Ortho-K is a non-surgical procedure that helps to correct nearsightedness by reshaping the cornea, which is quite popular nowadays. However, there are still both advantages and disadvantages. On the one hand, ortho-k lenses can provide good vision without surgical procedure and it is not painful and relatively less expensive than surgery. On the other hand, ortho-k treatment is time consuming, needing several visits to the eye-care doctor as well as several lens change and wearing retainer lenses will become imperative to ensure that the cornea does not revert to its original shape. Besides, the exact decrease in myopia cannot be guaranteed and the initial costs are higher compared with soft contact lenses. To sum up, you should weight the advantages and disadvantages careful by yourself.
