Additive manufacturing has been extensively used during the COVID-19 pandemic to design and produce protection equipment. During clinical examinations using slit lamps, ophthalmologists are at risk of being contaminated by the SARS-CoV-2 virus, and the device itself is exposed to viral contamination. Several solutions have already been proposed for fixing transparent shields on the physician side. Here we propose a 3D-printed device fixed on the chin rest on the patient side, aiming at limiting viral spread both on the lamp itself and towards the physician.
