Bausch + Lomb Announces Positive 24-Month U.S. Data on the ELIOS™ System for Treatment of Glaucoma

Mar 23 2026

Both primary effectiveness endpoints were met, demonstrating statistically significant and clinically meaningful intraocular pressure reduction.

VAUGHAN, Ontario--(BUSINESS WIRE)--Bausch + Lomb Corporation (NYSE/TSX: BLCO), a leading global eye health company dedicated to helping people see better to live better, today announced positive 24-month results from the pivotal U.S. clinical trial of the ELIOS System. Developed for the treatment of elevated intraocular pressure (IOP) in patients with open angle glaucoma, ELIOS is an implant-free procedure that uses next generation excimer laser technology. The ELIOS procedure is currently CE marked in Europe and is under development and has not been reviewed by the FDA for safety and efficacy in the United States.

“These strong U.S. study results reinforce everything we’ve learned about ELIOS during the years it has been available in Europe,” said Yehia Hashad, MD, executive vice president, R&D and chief medical officer, Bausch + Lomb. “Achieving meaningful reductions in intraocular pressure and freedom from medication for a majority of patients speaks to the promise of this technology. We look forward to sharing the full dataset with the broader ophthalmic community.”

In the prospective, multicenter study, investigators at 20 sites across the U.S. enrolled 318 patients taking glaucoma medications. Patients were previously diagnosed with mild to moderate primary open-angle glaucoma as well as cataracts. Two co-primary effectiveness endpoints were evaluated: the percentage of patients achieving at least a 20% reduction in IOP, and mean IOP reduction.

The ELIOS system met the study’s co-primary effectiveness endpoints, demonstrating both statistically significant and clinically meaningful IOP reduction. Key results included:

Unmedicated diurnal IOP (DIOP) was reduced by 20% or greater in 76% of patients
Patients experienced an average of 7.4 mmHg decrease in unmedicated DIOP
82% of patients were medication-free at 23 months
No intraoperative complications seen during the ELIOS procedure
Similar postoperative adverse event rate as cataract surgery alone

“The ELIOS procedure shows exciting potential for minimally invasive glaucoma treatment in the U.S., leveraging precision excimer laser technology to enhance the eye’s natural outflow pathways,” said Mark J Gallardo, MD, Glaucoma Fellowship Director at El Paso Eye Surgeons. “I believe glaucoma and cataract specialists alike will be very interested in the consistency of these impressive results as well as the demonstrated strong safety profile.”

These topline results will be discussed at 1:30 p.m. ET today during the inaugural Bausch + Lomb R&D Teach-in Webinar (register here). Detailed results from the pivotal trial will be submitted to a future medical meeting and a peer-reviewed journal.

About the ELIOS System and ELIOS Procedure
The ELIOS procedure is an implant-free, minimally invasive glaucoma procedure that uses excimer laser technology to create microchannels in the trabecular meshwork, facilitating aqueous outflow and reducing intraocular pressure.

ELIOS is currently under development in the United States and has not been reviewed by the U.S. Food and Drug Administration (FDA) for safety or effectiveness.

ELIOS has been available in Europe for several years, and data on the ELIOS procedure has been published in 12 clinical studies¹ with more than 850 eyes treated showing an IOP reduction of 20-40% from baseline, a significant reduction of medication for up to four years, up to 81% of patients “medication free” at one year,²and a favorable safety profile.

Over the past decade MIGS surgeries have transformed the treatment of mild to moderate glaucoma in Europe and have the potential to be an attractive alternative to more invasive incisional procedures such as trabeculectomy and tube shunts in the United States.
