Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Visual satisfaction measured using the mean of three questions each recorded on a 0 -100 visual analogue scale at each visit (baseline, V1 dispense, V2 10 +/- 3 days later, V3 10 +/- 3 days later, V4 10 +/- 3 days later) | — |
Secondary
| Measure | Time frame |
|---|---|
| Visual acuity measured using high and low LogMar visual acuity charts at a distance of 4 metres during each visit (baseline, V1 dispense, V2 10 +/- 3 days later, V3 10 +/- 3 days later, V4 10 +/- 3 days later) | — |
