Canaloplasty is a newer, less invasive surgical
procedure performed for treatment of open angle glaucoma. The procedure involves enlargement
of the eye’s natural drainage canal – the Schlemm’s Schlemm’s canal.
In this procedure: – A small opening is made in the sclera to
gain access to the Schemm’s canal. – A microcatheter, essentially a fiber-optic
tube, is inserted to encircle and enlarge the drainage canal.
– After a full circle of cannulation, the microcatheter is used to pull a suture through
the entire circumference of the canal. – The ends of the suture are then tied together
to provide tension to the inner wall of the canal and the associated trabecular meshwork.
This keeps the canal open and facilitates aqueous humor drainage.
