Alternative to LASIK surgery?

As an alternative to LASIK surgery, I remember recently seeing a report on TV about a new technique to "insert" a ring in the eye to alter the shape of the cornea as opposed to permanently reshaping it with a laser.  
This report stated that as opposed to the actual reshaping of the eye with the LASIK procedure, this procedure can be reversed by simply removing the ring.
What is this procedure named, and where is more information available?
