INTRODUCTION: In the midst of the SARS-CoV-2 virus (COVID-19) pandemic, health professionals, specifically gastroenterologists, have had to use personal protective equipment (PPE) to reduce contact with droplets and aerosols generated during gastrointestinal endoscopy. OBJECTIVE: To evaluate the impact of the use of two types of PPE on quality of vision during gastrointestinal endoscopy. METHODS: A cross-sectional observational pilot study in gastroenterologists who undergo an ophthalmological examination of visual acuity and quality of vision when using two types of PPE. Type #1: 3M N95 1860 green respirator + 3M mono safety glasses + protective screen. Type #2: 3M 6800 full facepiece + 3M NIOSH 7093C HF/P100 filters. RESULTS: Visual acuity and quality of vison parameters while using the PPE that is routinely used when performing gastrointestinal endoscopy during the pandemic were evaluated. It was found that Modality #1 was associated with decreases of up to 37% in visual acuity, 25% in colour visualisation and 75% in contrast sensitivity among digestive endoscopists within minutes of placement. These figures worsened over the course of the procedure, rising to 75%, 60% and 100%, respectively. Modality #2 was not associated with any deterioration in quality of vision. CONCLUSIONS: The different PPE modalities used during gastrointestinal endoscopy could have an impact on the quality of endoscopy studies performed during the SARS-CoV-2 (COVID-19) pandemic.
