My contact lens prescription is OD: -7.50 and OS: -9 and my glasses Rx is somewhere in this range too. I wear contact lenses most of the time and I am curious if there are any ortho-k lenses for high myopes? Most of the time I stumble upon information that the ortho-k lenses are able to correct up to -6 diopters of myopia but some websites say that it may go even higher than that.
You would be far better off in my opinion to either consider LASIK or the new SMILE procedure. Ortho-K is pretty much a waste of time and money, like trying to permanently get a new figure by wearing a girdle
