A Comparative Real-World Time And Motion Study Of Voyager™ Direct Selective Laser Trabeculoplasty To Conventional Selective Laser Trabeculoplasty

The Voyager™ Direct Selective Laser Trabeculoplasty (DSLT) device represents the first non-contact laser treatment for glaucoma and ocular hypertension that eliminates the need for a gonioscopy lens. DSLT offers a fully automated procedure that may reduce treatment time and minimize procedural complexity compared with conventional Selective Laser Trabeculoplasty (SLT). To assess its real-world impact, we conducted a prospective, comparative, observational time-and-motion study evaluating procedural efficiency for DSLT versus conventional SLT in subjects with mild to moderate glaucoma.

Single outpatient ophthalmology clinic, Fort Worth, Texas, United States of America.

Forty adult patients with mild to moderate glaucoma received either DSLT or SLT from a single experienced surgeon, based on routine clinical workflow and physician discretion. Patients with angle-closure, congenital, secondary glaucoma, or undergoing a second treatment during the trial period will be excluded. The primary endpoint is treatment administration time, defined as the time from the final anesthetic drop application until the removal of the last instrument. Secondary endpoints include patient-laser interaction time, physician time in treatment room, and patient time in treatment room. Results are presented as observed mean ± standard deviation. Data and statistical analyses are planned.

Enrollment occurred between October 2025 to February 2026. Among the study sample, 20 patients were diagnosed with mild glaucoma and 20 patients with moderate glaucoma. Treatment administration time was 1.61 ± 0.57 mins for DSLT and 6.83 ± 1.05 mins for SLT (observed mean difference: 5.22 mins). Patient-laser interaction time was 1.15 ± 0.59 mins for DSLT and 6.47 ± 1.05 mins for SLT (observed mean difference: 5.32 mins). Physician time in treatment room was 2.04 ± 0.61 mins for DSLT and 8.04 ± 1.02 mins for SLT (observed mean difference: 6.00 mins), and overall patient time in treatment room was 14.57 ± 6.21 mins for DSLT and 21.80 ± 8.19 mins for SLT (observed mean difference: 7.22 mins).

Results show Voyager™ DSLT procedure may enhance practice efficiency by enabling shorter treatment administration time, laser interaction time, physician time spent in the treatment room, and patient time in the treatment room. Statistical analyses will determine if Voyager™ DSLT is associated with statistically significant time savings compared to conventional SLT. Greater practice efficiency with Voyager™ DSLT may support increased patient throughput for glaucoma and ocular hypertension treatments.
