I know someone who was very disappointed as, although it corrected her short sight, she found herself suddenly needing reading glasses. I saw her again a few months later, and now she is used to using reading glasses, she is very happy.
BUT ... she was not very short sighted, and everything independent that I have read about it says that it is not as effective for the severely short sighted. In other words, you may have the treatment, but find that you still need glasses, albeit of lesser strength.
If you've used contact lenses successfully before, apart from the problem of sleeping in them by mistake, then it would be worth investigating. There have been huge advances in lenses, including daily disposables and lenses that you can sleep in.
