Surgical performance and the positivity rate for novel coronavirus (severe acute respiratory syndrome coronavirus 2) in an ophthalmic setup during the coronavirus disease 2019 pandemic

AIM: To describe, the impact of ongoing coronavirus disease 2019 (COVID-19) pandemic on ophthalmic surgeries at a tertiary eye care center of East India during and after the lockdown, and the positivity rate for novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]). MATERIALS AND METHODS: A retrospective study of all ophthalmic surgeries performed during and after lockdown from April 1, 2020 to August 31, 2020, with comparison to the corresponding period in the previous year (2019) was done. Eligible patients were tested for novel coronavirus (SARS-CoV-2) preoperatively as per the institutional protocols. RESULTS: A total of 569 surgeries were performed during the study period compared to 3458 performed in 2019, (P = 0.00001). The maximum number of surgeries were performed in June (191, 33.57%) and July (189, 33.22%) and in the subspecialty of vitreo-retina (337, 59.23%) followed by cataract (101, 17.75%). The most common vitreoretinal procedures were intravitreal injections (223, 66.17%) and retinal detachment surgery (56, 16.62%). Emergency surgeries performed were 30 (5.275%) compared to 76 (2.20%) during the same duration in the previous year (P = 0.00004). Ninety-four (16.52%) cases were screened for COVID-19. A total of 10 (10.64%) cases tested positive for SARS-CoV-2. Only one of these cases was symptomatic. CONCLUSION: There was a drastic decline in the number of both elective and emergency surgeries during and after the lockdown period of the COVID-19 pandemic when compared to the corresponding previous year duration. The maximum number of surgeries was performed in the vitreoretinal subspecialty. The positivity rate for SARS CoV-2 amongst the patients tested was 10.64% and most of these patients were asymptomatic.
