IRIX IRIDEX Corporation

Iridex Corporation (Nasdaq: IRIX), a worldwide leader providing innovative and versatile laser-based medical systems and delivery devices for the treatment of glaucoma and retinal diseases, today announced the publication of a landmark peer-reviewed study in Ophthalmology Therapy. This study highlights the sustained safety and efficacy of MicroPulse Transscleral Laser Therapy (TLT) (also referred to as Transscleral Cyclophotocoagulation) in managing both primary and secondary glaucoma over five years. Conducted by Dr. Ronald de Crom and colleagues at the University Eye Clinic Maastricht, Netherlands, this research is the first to evaluate outcomes of MicroPulse TLT over such an extended period.

The study assessed 165 pre- and post-cataract eyes treated between 2016 and 2019, with 112 eyes completing the five-year follow-up. Treatment was delivered using the Iridex Cyclo G6® Laser in its MicroPulse® Mode and the original MicroPulse P3® Delivery Device. Results demonstrated that MicroPulse TLT achieved significant (p<0.001) reductions in intraocular pressure (IOP)—32.5% on average—while also enabling a significant reduction (p<0.005) in IOP-lowering medications with a low rate of complications across a broad range of glaucoma types and severities.

"These findings suggest MicroPulse TLT can be a viable alternative to invasive incisional glaucoma surgery, particularly in patients with secondary glaucoma and those for whom incisional surgery may be challenging,” said Dr. de Crom. "Its ability to achieve sustained IOP reduction with minimal complications makes it a cornerstone treatment option."

Additionally, over the five-year follow-up period, only 38% of eyes required retreatment. “Patients who underwent retreatments achieved similar levels of success as those treated initially with no significant increase in complication risk.” Dr. de Crom continued, "The ability to safely repeat MicroPulse treatments while continuing long-term glaucoma care management without having to progress to more invasive glaucoma surgeries, is a huge advantage to clinicians and patients alike!"

Patrick Mercer, CEO of Iridex, commented, "This is the first long-term, peer-reviewed study that demonstrates the safety, effectiveness, and repeatability of MicroPulse TLT. This milestone study supports our commitment to delivering innovative, non-incisional solutions that improve patient outcomes while creating value for our investors and customers.”
