Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Implantation of STARflo glaucoma implant into the anterior chamber and suprachoroidal space. The STARflo glaucoma implant (v2.0) is a 5mm x 8mm silicone device made using a patented porous biomatrix designed to facilitate the flow of aqueous fluid through it and enhance compatibility with surrounding tissues. Implantation is performed via an external approach under local anaesthesia and is anticipated to take 45 - 60 minutes.
