Unlike face masks which provided some protection against both aerosols and droplets, slit lamp shields conferred protection only against direct large droplet transmission, with a limited role in reducing aerosol transmission risk. The SARS-CoV-2 is primarily transmitted via respiratory droplets, contact with 1 contaminated surfaces, or free-floating aerosols. We attempted to replicate the 5 spread of infected aerosols and large droplets in the clinical setting of a slit lamp 6 examination, to evaluate the efficacy of protective equipment in reducing the risk of viral 7 4 The experimental setup ( Figure S1 , available online at 12 www.aaojournal.org) consisted of a slit lamp (B900 Slit Lamp, Haag-Streit Holding AG, 13 Switzerland), a mannequin face which represented the ophthalmologist, and a spray bottle at 14 the chin rest which represented respiratory particle production from the patient. ./cache/cord-290414-8i8g0xdc.txt ./txt/cord-290414-8i8g0xdc.txt
