Purpose: To evaluate the impact of the changes in treatment patterns before, during and after the COVID‐19 pandemic on best‐corrected visual acuity (BCVA) in previously treated neovascular age‐related macular degeneration (nAMD) patients. Methods: A multi‐centre, retrospective, observational study of consecutive nAMD patients during 2019–2021. Data collected included demographics, BCVA, dates of intravitreal anti‐vascular endothelial growth factor (anti‐VEGF) injections and clinic visits. Results: A total of 1652 eyes of 1652 nAMD patients were included, out of which 850 eyes were assessed in 2019 (pre‐COVID‐19), 630 eyes were assessed in 2020 (COVID‐19) and 974 eyes were assessed in 2021 (post‐COVID‐19). During the COVID‐19 period, the mean number of anti‐VEGF injections was significantly lower than the corresponding pre‐COVID‐19 and post‐COVID‐19 periods (5.55 compared to 6.13 and 6.60, respectively p < 0.01). A constant lower ratio of injections per patient/month was observed during COVID‐19 compared to previous and following years, with a notable decline during March–April, reaching a ratio of 0.4 in 2020 versus 0.65 in 2019 and 0.62 in 2021 (p < 0.01). Baseline BCVA (0.825, p < 0.001), number of injections (−0.007, p < 0.001), gender (−0.027, p = 0.037) and age (0.004, p < 0.001) were shown to be significant predictors of final BCVA. Conclusion: During the COVID‐19 period, patients were treated with significantly less intravitreal anti‐VEGF injection compared to the previous year with compensation in the following year. These changes in treatment patterns did not have a significant impact on BCVA outcomes. Age, gender, baseline BCVA and number of injections are predictors of final visual outcomes.
