• Even before the patient enters the examination room, adhesive medical tape can be used to affix the top of the patient's mask at the dorsum of his/her nose and the cheekbones. Porous and hypoallergenic tapes can be used for patients with sweaty or sensitive skin. 3 This should be done by staff using disposable gloves and ensures that the patient wears the mask properly not only during the slit-lamp examination, but throughout the consultation. • Lens fogging occurs when the warm water vapor condenses on the cooler surface of the lens and forms tiny light-scattering droplets. Washing the lens 

Open Access Full Text Article with soapy water leaves a thin surfactant layer that reduces the surface tension and causes the water molecules to spread out evenly, thus forming a transparent layer. Therefore, the lens is less likely to mist up during the examination. 4 • Finally, especially in patients with less-than-ideal cooperation during funduscopy (eg children), we have found the use of a non-mydriatic fundus camera extremely useful for the examination of the posterior pole.

We hope these alternatives will be useful to colleagues during such challenging times.
