Abstract
In the normal eye the conventional outflow pathway is responsible for the majority of aqueous humor egress and plays a key role in the
maintenance of healthy intraocular pressure. However, in the glaucomatous eye pathologic changes to the pathway in the trabecular
meshwork, Schlemm’s canal, and collector channel ostia can introduce abnormal resistance to outflow with consequent increase in
intraocular pressure. The OMNI Surgical System (Sight Sciences, Menlo Park, CA USA) is a relatively new surgical device and the
only one that combines two ab interno minimally invasive treatments in a single procedure, canaloplasty and trabeculotomy. This new
technology allows surgeons to address outflow resistance wherever it may be, both proximally (juxtacanalicular trabecular meshwork
and inner wall of Schlemm’s canal), and distally (Schlemm’s canal and the collector channels). This review covers several recent
clinical studies of the OMNI device with the aim of collating what is known and what remains to be learned.
