Design outcomes
Primary
| Measure | Time frame |
|---|---|
| After 12 months of follow-up, a significant reduction in intraocular pressure, of approximately one-third of the preoperative value, is expected in both the experimental group and the control group | — |
Secondary
| Measure | Time frame |
|---|---|
| A significant reduction in the number of hypotensive eye drops required for intraocular pressure control is also expected, with the reduction being on the order of two eye drops in both groups;It is presumed that certain preoperative factors may be considered significant for surgical success or failure: the number of hypotensive eye drops, oral acetazolamide use, race, age, and sex | — |
