Outcome Measures

Primary Outcomes (2)

  • Change From Baseline in Mean Intraocular Pressure (IOP) to 36 Months After Implantation

    IOP is a measurement of the fluid pressure inside the eye. A negative change from Baseline indicates an improvement.

    Baseline (Day decision was made to implant XEN 45 Gel Stent) to 36 months after implantation

  • Change From Baseline in the Number of Topical IOP-lowering Medications 36 Months After Implantation

    IOP-lowering medications included Beta blocking agents, Carbonic anhydrase inhibitors, Parasympathomimetics, Prostaglandin analogues, and Sympathomimetics in glaucoma therapy.

    Baseline (Day decision was made to implant XEN 45 Gel Stent) to 36 months after implantation

Secondary Outcomes (7)

  • Change From Baseline in Mean IOP to 48 Months After Implantation

    Baseline (Day decision was made to implant XEN 45 Gel Stent) to 48 months after implantation

  • Change From Baseline in the Number of Topical IOP-lowering Medications 48 Months After Implantation

    Baseline (Day decision was made to implant XEN 45 Gel Stent) to 48 months after implantation

  • Percentage of Eyes Achieving Qualified Success at Month 36

    Baseline (Day decision was made to implant XEN 45 Gel Stent), Month 36

  • Percentage of Eyes Achieving Qualified Success at Month 48

    Baseline (Day decision was made to implant XEN 45 Gel Stent), Month 48

  • Percentage of Eyes Achieving Complete Success at Month 36

Study Arms (2)

Implant

Chart review was conducted in participants with open angle glaucoma who underwent placement of the implant XEN 45 Gel Stent as a standalone procedure from 1 January 2014 to 1 October 2015. For each eye selected, all retrospective data available from baseline (day when decision was made to implant XEN 45 Gel Stent) until the last visit was extracted from existing medical records.

Device: XEN Group

Implant + Phaco

Chart review was conducted in participants with open angle glaucoma who underwent placement of the implant XEN 45 Gel Stent in combination with phacoemulsification (Phaco) from 1 January 2014 to 1 October 2015. For each eye selected, all retrospective data available from baseline (day when decision was made to implant XEN 45 Gel Stent) until the last visit was extracted from existing medical records.

Procedure: Phacoemulsification
