Inclusion criteria

  1. Male or female subjects, 45 years or older.
  2. History of uncomplicated cataract surgery and posterior chamber intraocular lens (IOL) implantation without compromise to the lens capsule, zonular dehiscence/rupture or vitreous prolapse, 6 months or more prior to Baseline Visit (pseudophakic subjects), OR, phakic and no anticipated need for cataract surgery over the study duration.
  3. Under treatment with a topical prostaglandin F2 analog (e.g. latanoprost, travoprost, bimatoprost, tafluprost) either as monotherapy or in combination with one (1) adjunctive medication for a minimum of 6 weeks prior to the Screening visit.
  4. Intraocular pressure (IOP) at the Screening visit of >18 and not exceeding 36 mmHg.
  5. Diagnosed with primary open angle glaucoma (POAG).

Exclusion criteria

Exclusion Criteria:

  1. Any of the following prior ocular procedures:

    • Laser trabeculoplasty ≤180 days prior to baseline
    • Durysta ≤12 months prior to baseline unless failure is documented and topical medication including a prostaglandin analog is in use as per Inclusion criterion # 3.
    • Implanted with iStent (All types), Cypass, Xen, Express, glaucoma draining device/valve, or Hydrus Device; or
    • Prior canaloplasty, goniotomy, trabeculotomy, trabeculectomy, endoscopic cyclophotocoagulation (ECP), Cyclophotocoagulation or CPC (G probe)
    • Retinal laser procedure ≤3 months prior to baseline
  2. Concurrent IOP-lowering procedure other than the study procedure (OSS) (e.g. ECP, CPC,etc.)
  3. Forms of glaucoma other than POAG including but not limited to: Pigmentary, pseudoexfoliative, acute angle closure, normal tension, pre-perimetric, traumatic, congenital, malignant, uveitic, neovascular or severe glaucoma as documented in subject's medical record.
  4. Women of childbearing potential if they are currently pregnant or intend to become pregnant during the study period; are breast-feeding; or are not in agreement to use adequate birth control methods to prevent pregnancy throughout the study

Study arms

  • Active comparator
    Surgical (OMNI Surgical System (OSS))

    Canaloplasty followed by Trabeculotomy using the OMNI Surgical System.

    Device: OMNI Surgical System

  • Active comparator
    Standard Medical Care (SMC)

    Standard Medical Care with Latanoprost and one or two adjunctive glaucoma medications at the discretion of the Principal Investigator

    Drug: Latanoprost plus adjunctive glaucoma medication

Interventions

  • DeviceOMNI Surgical System

    The OMNI Surgical System is 510(k) cleared and indicated for canaloplasty (microcatheterization and transluminal viscodilation of Schlemm's canal) followed by trabeculotomy (cutting of trabecular meshwork) to reduce intraocular pressure in adult patients with primary open-angle glaucoma

    Also known as: OMNI

  • DrugLatanoprost plus adjunctive glaucoma medication

    * Latanoprost ophthalmic solution (0.005%) is a topical prostaglandin F2 analog used in the treatment of Glaucoma. * Adjunctive topical glaucoma medication(s) as selected by the Investigator
