Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Visual acuity (VA) measured using high- and low-contrast conditions using a logMAR visual acuity chart at screening (visit 1), baseline (visit 2), and at follow-ups at 3, 6 and 12 months (visits 3, 4, and 5) | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Axial length (length of the eye) will be measured using non-contact biometry (IOLMaster 500/700) using standard operating procedures at baseline (visit 2), and at follow-ups at 3, 6 and 12 months (visits 3, 4, and 5) 2. Choroidal thickness measured using a non-contact spectral domain optical coherence tomography at baseline (visit 2), and at follow-ups at 3, 6 and 12 months (visits 3, 4, and 5) | — |
