Abstract
PURPOSE: To describe the impact of lockdown and unlock phases of the COVID-19 pandemic on cataract surgery at a multitier ophthalmology network. METHODS: This cross-sectional hospital-based study included 106,279 eyes operated between March 23, 2019 and March 31, 2021. The data of patients who underwent cataract surgery presenting during the lockdown and unlock phases were compared with the respective periods in the previous year before COVID-19. RESULTS: The cataract surgeries performed decreased to 5.6% (839/14,994) of pre-COVID-19 volumes during the lockdown phase. There was a gradual recovery of the cataract surgeries performed to 86.7% of pre-COVID-19 volumes by May 2020 and exceeded by 17.9% by September 2020. There was a decrease in the number of women who underwent cataract surgery during the lockdown phase (49.11%) compared to the pre-COVID-19 (52.59%) or unlock phase (52.29%, P < 0.001). Patients operated during the lockdown phase were younger when compared to other groups (P < 0.001). The mean LogMAR presenting visual acuity at the time of surgery was worse in patients operated during the lockdown phase (1.84 ± 1.16) as compared to pre-COVID-19 (1.39 ± 1.05) and unlock phases (1.51 ± 1.08, P =<0.001). The proportion of patients with total cataracts were higher during the lockdown and unlock phases compared to the pre-COVID-19 phase (P < 0.001). CONCLUSION: The first year of the COVID-19 pandemic saw a drastic reduction in the surgical volume in the lockdown phase, which recovered quickly during the unlock period. Patients of younger age, male gender, poor presenting visual acuity, denser cataracts, and living close to the surgical center were able to access surgical care due to lockdown restrictions.
