Canaloplasty is a Glaucoma surgery to open the Schlemm's Canal under the limbus. The Schlemm's Canal carries aqueous fluid from the anterior chamber of the eye to the bloodstream. So
after making a small incision to get to Schlemm's Canal the Ophthalmologist will use a microcatheter with a blinking light at the end and feed it all the way around the Schlemm's Canal, once all the way around they will tie a Suture on the end of the
microcatheter. After making sure the suture won't come off they pull the microcatheter back around the canal and as they are doing that the catheter has a gel-like fluid in it to help keep the canal open. After they have removed the microcatheter they use the suture that
was on the end of that and tie it together so the sutures will help keep the canal open. Once that is complete they cut the excess sutures and the suture up the flap that they made.
The photos below are pictures of the process of a Canaloplasty, they are in no particular order.
