Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Intra Ocular Pressure (IOP) | Change in IOP from baseline to IOP during surgery and to one week and to three months following surgery | IOP measurement will be taken before, during and after surgery using ICARE tonometer |
| Retinal Nerve Fiber Layer Thickness (RNFL) using OCT | Change in OCT RNFL thickness from baseline to OCT RNFL thickness during surgery and to one week and to three months following surgery | RNFL measurement will be taken before and after surgery using spectralis OCT |
