At the European Glaucoma Society Congress, Professor Gus Gazzard presented the five-year findings from the HORIZON study, the largest randomized controlled trial to evaluate the Hydrus Microstent in glaucoma surgery. The study, encompassing a significant follow-up rate of 80%, demonstrated that 77.2% of patients experienced at least a 20% reduction in intraocular pressure (IOP) without medication at 24 months. Additionally, the Hydrus Microstent significantly decreased postoperative IOP spikes and reduced the need for further surgeries over five years, supporting its efficacy as a treatment option.
