| E.5 End points |
| E.5.1 | Primary end point(s) |
| Best Corrected Visual Acuity (BCVA) is the primary efficacy variable and will be measured using the ETDRS method. It will be measured in both eyes (study eye and non-study eye) at the qualification visit and each follow-up visit. BCVA will be performed following manifest refraction, except 1, 7 and 21 days after the study treatment or re-treatment,. At days 1, 7 and 21 after a treatment or re-treatment, visual acuity (VA) evaluations may be performed using refraction obtained at baseline or at the preceding re-treatment visit, respectively. These VA evaluations will be considered as safety measures but not as efficacy measures. All other VA evaluations will be considered as both safety and efficacy measures. |
