简要总结
The primary objective of this study is to evaluate the safety and effectiveness of the Bionode IOP lowering system in eyes with elevated IOP. The contact lens being studied is similar to an ordinary contact lens that is worn to correct nearsightedness. But the study contact lens has been designed with a thin gold coil around the outside edge of the lens. This design helps deliver a low amount of energy to the eye, which is expected to help lower the pressure inside of the eye. The study contact lens is activated by a pair of glasses (Bionode spectacles) that you wear to apply the treatment to your eye. The study contact lens is only activated when the study glasses are activated.
详细描述
Subjects will be randomized in 1:1 ratio into two groups, designated Group A and Group B. During the study, randomized subjects will be fitted with a pair of study contact lenses, only one of which is embedded with a gold coil to receive electrical stimulation from the study spectacles, in the study eye. Subjects will also wear optical spectacles (study spectacles) that deliver the electrical stimulus the study contact lenses.
Group A will receive electrical stimulation (test group), and Group B will not receive electrical stimulation (control group). Baseline IOP will be recorded prior to the 2-hours stimulation, and will be repeated post-therapy, at increments of 5 minutes, 30 minutes, 60 minutes, and 2 hours from the conclusion of stimulation. The total duration of participation for each subject is up to approximately 5 weeks. The total expected duration of the clinical trial is approximately 4 months.

结局指标
主要结局
Intraocular pressure (mmHg)
时间窗: 0 min (baseline), 5 min, 30 min, 60 min, and 120 min post treatment
The primary effectiveness outcome is defined unmedicated IOP after treatment, at 0 min (baseline), 5 min, 30 min, 60 min, and 120 min. An area under the curve will be calculated from the IOP measures at the 5 time points.
Number of patients with treatment related adverse events
时间窗: 1 month post treatment
