About this trial

This is an interventional treatment trial for Glaucoma, Open-Angle

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female subjects, 18 years or older
  2. Pseudophakic
  3. Diagnosis of open angle glaucoma (OAG)
  4. On 1-5 ocular hypotensive medications

Exclusion Criteria:

  1. Any of the following prior treatments for glaucoma:

    • Suprachoroidal stent (e.g. Cypass, iStent Supra)
    • Laser trabeculoplasty ≤ 8 weeks prior to Baseline visit with a MIGS or other glaucoma device including but not limited to iStent, iStent inject, Hydrus, CyPass
    • Trabeculectomy or other bleb forming procedure including Xen, PreserFlo, Express, glaucoma draining device/valve
    • Prior canaloplasty, goniotomy, or trabeculotomy including procedures with GATT, Kahook Dual Blade, iTrack, Trabectome
    • Ciliary ablation procedures including Endocyclophotocoagulation (ECP), Cyclophotocoagulation (G probe), Micropulse laser, or high intensity focused ultrasound (HIFU)
  2. Any other form of glaucoma other than OAG
  3. Concurrent ocular pathology or systemic medical condition which, in the Investigator's judgment, would either place the subject at increased risk of complications, contraindicate surgery, place the subject at risk of significant vision loss during the study period (e.g., wet AMD, corneal edema, Fuch's dystrophy, active intraocular infection or inflammation within 30 days prior to Screening Visit, etc.), or interfere with compliance to elements of the study protocol (e.g., returning to investigator's office for follow-up visits).
  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.

5. Study Description

Brief Summary
First, to compare safety and effectiveness outcomes for canaloplasty and trabeculotomy using the OMNI Surgical System to implantation of the iStent inject in lowering intraocular pressure (IOP) in pseudophakic eyes with open angle glaucoma (OAG), and second, to compare safety and effectiveness outcomes for canaloplasty alone (using the OMNI Surgical System)to implantation of the iStent Inject in lowering IOP in pseudophakic eyes with OAG.
