Study summary

The goal of this study is to learn about outcomes after bio-reinforced canaloplasty surgery in patients with OAG. The key question the study aims to answer is:

How much does the surgical procedure lower pressure inside the eye and what is the durability of this effect?

Participants will return for periodic eye exams for 2 years following surgery.

Read the detailed description

The purpose of this observational study is to evaluate postoperative outcomes in a real-world setting after bio-reinforced canaloplasty in eyes with OAG. Outcomes of interest include change in intraocular pressure (IOP), change in use of glaucoma medications, related adverse events, and surgical reinterventions for additional IOP control.

Patients will be approached for study enrollment based on investigator determination that surgical intervention is necessary to maintain target IOP and the patient may benefit from bio-reinforced canaloplasty.

After surgery, data will be collected from participant examinations on Day 1 and at approximately 1, 3, 6, 12, 18 and 24 months. Examinations at each visit are performed per the investigator's standard of care.

Study population

Patients with OAG who are determined to need surgical intervention for maintenance of target IOP

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

1. Diagnosis of OAG in the study eye and a candidate for bio-reinforced canaloplasty for aqueous outflow enhancement, as determined by investigator

Exclusion criteria

Exclusion Criteria:

1. Diagnosis of acute angle closure, traumatic, congenital, malignant, uveitic, or neovascular glaucoma in the study eye 2. Previous minimally invasive or filtering glaucoma surgery in the study eye 3. Previous IOP-lowering procedure ≤ 12 weeks prior to bio-reinforced canaloplasty in the study eye 5. Previous , or non-standard of care procedures and/or treatments ≤ 12 weeks prior to bio-reinforced canaloplasty

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Groups and cohorts

  • Bio-reinforced canaloplasty

    Participants with OAG who undergo canaloplasty followed by intraluminal placement of minimally manipulated, homologous-use scleral allograft tissue within Schlemm's canal lumen.

    Procedure: AlloSpan Canal Platform Bio-Reinforced Canaloplasty

Interventions

  • ProcedureAlloSpan Canal Platform Bio-Reinforced Canaloplasty

    A canaloplasty procedure is performed using AlloSpan Canal manual surgical instrumentation. After canaloplasty, minimally manipulated, homologous-use scleral allograft tissue is placed within in the canal-wall region of the Schlemm's canal lumen to provide structural reinforcement.
