As an alternative to vision correction surgeries for near-sightedness like Lasik, some practitioners and patients are experimenting with orthokeratology, in which specially designed gas permeable contact lenses are worn only at night, and during that time the lenses reshape the cornea to allow clear vision without lenses during the day. Unlike surgery, it has no real risks, as long as you keep your lenses clean, and is completely reversible. The disadvantage is that if you stop wearing the lenses at night your vision regresses back to where you started within a few days. Apparently this approach has been around a long time, but new lens materials and computer-controlled manufacturing techniques have made it more likely to succeed.
Question: Has anybody tried this? Has it worked? Are you happy with the results?
