====Canaloplasty====
[[Canaloplasty]] is a nonpenetrating procedure using micro[[catheter]] technology. To perform a canaloplasty, an incision is made into the eye to gain access to the [[Schlemm's canal]] in a similar fashion to a viscocanalostomy. A microcatheter will circumnavigate the canal around the iris, enlarging the main drainage channel and its smaller collector channels through the injection of a sterile, gel-like material called [[viscoelastic]]. The catheter is then removed and a suture is placed within the canal and tightened.

By opening the canal, the pressure inside the eye may be relieved, although the reason is unclear, since the canal (of Schlemm) does not have any significant fluid resistance in glaucoma or healthy eyes. Long-term results are not available.<ref>{{cite journal | vauthors = Shingleton B, Tetz M, Korber N | title = Circumferential viscodilation and tensioning of Schlemm canal (canaloplasty) with temporal clear corneal phacoemulsification cataract surgery for open-angle glaucoma and visually significant cataract: one-year results | journal = Journal of Cataract and Refractive Surgery | volume = 34 | issue = 3 | pages = 433–440 | date = March 2008 | pmid = 18299068 | doi = 10.1016/j.jcrs.2007.11.029 | s2cid = 23904366 }}</ref><ref>{{cite journal | vauthors = Lewis RA, von Wolff K, Tetz M, Korber N, Kearney JR, Shingleton B, Samuelson TW | title = Canaloplasty: circumferential viscodilation and tensioning of Schlemm's canal using a flexible microcatheter for the treatment of open-angle glaucoma in adults: interim clinical study analysis | journal = Journal of Cataract and Refractive Surgery | volume = 33 | issue = 7 | pages = 1217–1226 | date = July 2007 | pmid = 17586378 | doi = 10.1016/j.jcrs.2007.03.051 | s2cid = 36397585 }}</ref>
