Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The frequency and severity of all treatment-related adverse events, during and after the g-STEAM Procedure for first month and throughout the 6-month follow-up period. Adverse events will be assessed on a continuous basis from the day of the procedure through the study completion at 6 months. 2. Need for adjunct surgery 3. Presence Inflammatory markers in tear secretion 4. Any Complications 5. Any significant changes on Ultrasound bio-microscopy (UBM)Timepoint: First Phase Day 0, 60 minutes, Day 1, 7, 30, 90 Second Phase: Day 0, 60 minutes, Day 1, 7, 30, 90, 180, 360 (optional) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. IOP measured by GAT or by Tonopen in case of irregular cornea. 2. ECD/ECC if permitted by the corneal clarity 3. Elevation Inflammatory markers in tears such as IL6, TNFa, IL1b, MMP9, IL8, bFGF, TGFb, TIMP1 4.PRO and related collateral effects For Sighted Eyes: Additionally, the following endpoints will be measured: 1. Visual Field Assessment 2. Best Corrected Distance Visual Acuity (BCVA)Timepoint: First Phase Day 0, 60 minutes, Day 1, 7, 30, 90 Second Phase: Day 0, 60 minutes, Day 1, 7, 30, 90, 180, 360 (optional) | — |
