The use of properly worn face masks by patients during slit-lamp examinations has become imperative during the COVID-19 pandemic. Unfortunately, vapor escaping from the top of a patient’s mask can form condensation on the cool surface of handheld examination lenses. This can make critical ophthalmic examinations such as funduscopy or gonioscopy very challenging. Pressing the patient’s top of the mask
against the dorsum of the nose or the cheekbones ensures that vapor exhaled by the patient is directed away from the lens, thus avoiding lens fogging. However, touching the patient’s mask carries the risk of contamination. In this article, we offer alternatives to tackle the problem of hand-held examination lens fogging due to face masks, while avoiding the risk of SARS-CoV-2 contamination.
