New Touch-Free laser offers hope for glaucoma patients who need a second treatment
NCT ID NCT07589270
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new laser treatment called DSLT for people with high eye pressure or open-angle glaucoma who have already had a similar laser (SLT). The DSLT laser does not touch the eye, which may make it faster and more comfortable. Researchers want to see how well it lowers eye pressure after 6 months in 60 adults.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Direct Selective Laser Trabeculoplasty (DSLT) using the Voyager™ device
- What this could lead to
- If successful, this could offer a quick, comfortable laser option for glaucoma patients who need additional pressure lowering after a previous laser treatment.
- What could go wrong
- This is a small, early-stage study with no control group, so results may not apply broadly. The pressure-lowering effect may be modest or short-lived in these previously treated patients.

Inclusion Criteria: * • Adult patients (18-80 years old), scheduled to undergo DSLT treatment in one eye. * Diagnosis of ocular hypertension (OHTN) or primary open angle glaucoma (POAG). * Previous history of selective laser trabeculoplasty (SLT) treatment. • Medication free or washed out IOP at time 0 ranging from ≥ 18 through 32 mm Hg. Exclusion Criteria: * • Screened patients who were on IOP-lowering medications who did not successfully complete medication washout at the time of the procedure (time 0) * Previous glaucoma surgeries/interventions: * Patients who have undergone prior glaucoma-related procedures (e.g., trabeculectomy, laser trabeculoplasty, MIGS, or tube shunt). * Recent SLT failures (within 6 months of initial treatment). * Patients who have undergone cataract surgery within the prior 2 years. * Secondary glaucoma: o Patients with secondary forms of glaucoma, such as angle-closure glaucoma, neovascular glaucoma, or glaucoma resulting from trauma or other systemic diseases. * Other significant ocular conditions including advanced cataracts, retinal diseases (e.g., age-related macular degeneration), or any condition that might complicate the assessment of intraocular pressure (IOP) or visual function as deemed by the investigator.
