Canaloplasty has been approved by the FDA since 2008. So as of 2012, we have three-year published results, which indicate that the pressure lowering effect of canaloplasty is stable over those three years. Now, three years may not sound like very long, but the older style of surgery, viscocanalostomy, on which canaloplasty is an improvement, has results seven years out. And the seven-year results look very good for that surgery. Since canaloplasty adds to viscocanaloplasty by restoring the natural drainage duct and keeping it open with a stent, we can only imagine that the long term results of canaloplasty are going to be even more impressive.
