MOUNTAIN VIEW, Calif., Jan. 24, 2024 (GLOBE NEWSWIRE) -- Iridex Corporation, headquartered in Mountain View, California, and Imperial College Healthcare NHS Trust in London, today announced the first patient enrollment in a collaborative medical research study and registry evaluating the treatment of glaucoma with MicroPulse® Transscleral Laser Therapy (TLT) using Iridex’ Cyclo G6® Laser and the MicroPulse P3® Delivery Device. This partnership establishes a large-scale enrollment platform to advance clinical research.

David I. Bruce, President and CEO of Iridex, shared: "The first patient enrollment in this partnership with Imperial College Healthcare NHS Trust is the first step toward multicenter participation enabling a large-scale view and significant in-country impact of our MicroPulse® technology.”

The study, titled "MicroPulse Transscleral Laser Therapy: A Prospective UK Study," is set to expand Iridex’s global clinical portfolio, through its commitment to funding essential components of the 3-year study and providing a custom-designed and secure database management system.

Professor Philip Bloom, Consultant Ophthalmic Surgeon at Imperial College Healthcare NHS Trust, emphasized the importance of rapid expansion: “We are delighted at Imperial to be able now to offer this minimally invasive treatment for glaucoma. Expansion to include other units will be crucial in advancing glaucoma treatment in the UK. Our partnership with Iridex is key to enhancing this study's reach and impact.” 

The Western Eye Glaucoma Department of the Imperial College Healthcare NHS Trust is the first to implement MicroPulse® TLT as part of this clinical research registry, adhering to NICE IPG692 guidelines. The registry and study is structured for expanded participation from other UK providers to join the program and build enrollment for large patient cohorts.

Both Iridex and Imperial College Healthcare NHS Trust are dedicated to conducting this study in accordance with the strictest ethical and regulatory standards and look forward to welcoming additional sites to join the program. The collaboration symbolizes the company’s shared vision for advancing medical science with MicroPulse® TLT. It promises significant insights and advancements in glaucoma laser therapy, potentially revolutionizing treatment approaches and enhancing patient care.
