Characterizing the microbiota of instrumentation in ophthalmology clinics during and beyond the COVID-19 pandemic.

Graefes Arch Clin Exp Ophthalmol 2022 Mar 31. Epub 2022 Mar 31.

Wilmer Eye Institute, Johns Hopkins University School of Medicine, Johns Hopkins Hospital, 600 N Wolfe St, Baltimore, MD, 21287, USA.

Purpose: Increased ophthalmology-specific risk of novel coronavirus 2019 (SARS-CoV-2) transmission is well-established, increasing the fear of infection and causing associated decreased rates of procedures known to save vision. However, the potential transmission from exposure to clinic instrumentation is unknown, including which additional pathogens may be spreading in this context. This study seeks to fill this gap by characterizing the microbiota of instrumentation in ophthalmology clinics during the COVID-19 pandemic and identifying potential sources of pathogenic spread encountered by patients and healthcare workers.
