The MINIjectTM STAR-I study is a prospective, open, multi-centre clinical trial analysing the efficacy and safety of the MINIject investigational device in 25 patients with open angle glaucoma uncontrolled by topical hypotensive medications. MINIject is intended to be used to reduce intraocular pressure (IOP) by channelling aqueous humor out of the anterior chamber to the supraciliary space, thus enhancing the physiological uveoscleral outflow. The primary endpoint is the absolute reduction in mean diurnal IOP compared to baseline at 6-month follow-up. Secondary endpoints include IOP reduction at 12 and 24-month follow-up, the reduction in the number of topical hypotensive medications at 6, 12 and 24-months compared to baseline, and safety. This trial has been registered on (NCT03193736). Further information can be found at

Primary endpoint results showed that the implantation of MINIject resulted in an average 39% IOP reduction to a mean of 14.2 mmHg at six months, using a mean of 0.3 IOP-lowering medications. At one year, mean IOP was 15.6mmHg with 75% of patients still able to discontinue topical medication usage, remaining medication-free at 12 months. There were no serious adverse events related to the device or the procedure, and no patient required additional glaucoma surgery.

Clinical Trials

There are 2 on-going trials studying the STARflo device.


The STARfloTM European Safety and Efficacy Study is a post-market, prospective, multi-centre clinical trial of the STARflo Glaucoma implant in approximately 50 patients in Europe. The primary endpoint is the reduction in mean diurnal IOP at month 12 vs baseline. Secondary endpoints include safety and the reduction of IOP-lowering medication use. Final results are expected in 2020. This trial has been registered on (NCT02272569). Further information can be found at

The STAR-LIFE study is a registry with the aim of documenting the benefit to patients following the implantation of the STARflo­ implant in a “real-world” patient population, and to learn about surgical practices. The objective is to document the implant’s effectiveness in terms of IOP reduction in open angle glaucoma patients and the reduction in the number of concomitant IOP-lowering medications. The study is designed to allow collection of patient data either retrospectively or prospectively for up to 5 years post-implantation in up to 150 patients. This trial has been registered on (NCT02825264). Further information can be found at
