Brief Summary:
This study will prospectively assess the clinical effect of ab-interno transluminal viscoelastic delivery and trabeculotomy performed using the OMNI Surgical System in combination with Cataract Extraction on intraocular pressure (IOP) and the use of IOP-lowering medications in patients with mild-moderate open angle glaucoma (OAG).

Condition or disease Intervention/treatment Phase
Open Angle Glaucoma Device: Transluminal viscoelastic delivery and trabeculotomy Not Applicable

Detailed Description:
This prospective, multicenter, single-arm, post-market clinical study will evaluate the impact of ab-interno transluminal viscoelastic delivery and trabeculotomy using OMNI Surgical System in conjunction with cataract surgery on IOP and the use of hypotensive medications in patients with mild to moderate open angle glaucoma.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in mean unmedicated diurnal IOP [ Time Frame: 12 months ]
    Reduction in mean unmedicated diurnal IOP from baseline to 12 months

  2. Change in mean number of IOP-lowering medications [ Time Frame: 12 months ]
    Reduction in mean number of IOP-lowering medications from screening to 12 months


Secondary Outcome Measures :
  1. Percent of eyes with a ≥20% reduction in unmedicated diurnal IOP at 12 months [ Time Frame: 12 months ]
  2. Percent of eyes with unmedicated diurnal IOP between 6 and 18 mmHg inclusive at 12 months [ Time Frame: 12 months ]

Other Outcome Measures:
  1. Safety Endpoint- Adverse events [ Time Frame: 12 months ]
    Rates of ocular adverse events (intraoperative, postoperative)

  2. Safety Endpoint- best corrected visual acuity [ Time Frame: 12 months ]
    Reduction in best corrected visual acuity (BCVA) from baseline (note: reduction in BCVA due to PCO will not be treated as a safety event)

Layout table for eligibility information
Ages Eligible for Study:   22 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

- (only one eye of each subject is eligible, and all ocular criteria apply to the study eye):

  1. Male or female subjects, 22 years or older.
  2. Visually significant cataract
  3. Diagnosed with mild to moderate open angle glaucoma (e.g. primary open angle glaucoma, pigmentary glaucoma, pseudoexfoliative glaucoma) per AAO/AGS/ICD-10 Glaucoma Stage Definitions.1
  4. At screening, on 1-3 IOP-lowering medications2 with a medicated IOP ≤25 mmHg OR on zero (0) IOP-lowering medications with an IOP 21-30 mmHg.
  5. At baseline, unmedicated diurnal IOP 21-30 mmHg and, for subjects who were medicated at screening, IOP at least 3 mmHg higher than screening IOP.
  6. Scheduled for cataract extraction followed by abinterno transluminal viscoelastic delivery and trabeculotomy using the OMNI Surgical System.
  7. Shaffer grade of ≥ III in all four quadrants
  8. Potential of good best corrected visual acuity post cataract extraction, in the investigator's judgment
  9. Able and willing to comply with the protocol, including all follow-up visits.
  10. Understands and signs the informed consent.

Exclusion Criteria:

- (All criteria apply to the study eye; both eyes of a single subject need not be eligible):

  1. Any of the following prior treatments for glaucoma:

    • Laser trabeculoplasty ≤3 months prior to baseline
    • iStent implanted ≤6 months prior to baseline
    • Implanted with Cypass, Xen, Express, glaucoma draining device/valve, or Hydrus Device
    • Prior canaloplasty, goniotomy, trabeculotomy, trabeculectomy, ECP or CPC
  2. Normal tension glaucoma
  3. Acute angle closure, traumatic, congenital, malignant, uveitic or neovascular glaucoma
  4. Severe glaucoma by AAO/AGS/ICD-10 guideline
  5. Use of oral hypotensive medication treatment for glaucoma
  6. History of elevated IOP due to steroid response
  7. In the investigator's judgement, predisposed to significant risk because of washout of ocular hypotensive medications.
  8. Ocular pathology or 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, etc.), or interfere with compliance to elements of the study protocol (e.g., returning to investigator's office for follow-up visits).
  9. Participation (≤ 30 days prior to baseline) in an interventional trial which could have a potential effect on the study outcome, as determined by the study investigator.
