Abstract: Introduction. The new coronavirus SARS-CoV-2 is transmitted through droplets that an infected person expels while coughing, sneezing, or talking, and it mainly affects the respiratory tract. To this date, there are no treatments, so preventive measures are necessary to restrain its spread. Materials and methods. In Mexico, authorities declared the sanitary emergency on March 30th. From this moment, we began a thorough literature review in PUBMED on the preventive measures for COVID-19 issued by ophthalmological societies. While two researchers went through the titles and abstracts, three dedicated themselves to text analysis. The search strategy is based on the MeSH terms: Wuhan, COVID-19, SARS-CoV-2, Health Workers, Prevention, Guidelines, Patients, and Ophthalmology. The focus is on four critical areas in the management of patients during the outbreak of COVID-19, expressly, user and environmental control, in addition to protection of HCP and overall administrative matters. From these, we derived 15 recommendations, which we, in turn, looked for in each paper. Results. 25 articles were analyzed. The most consistently observed recommendations were: use of personal protective equipment (PPE) (100%), disinfection of patient zones (100%), respiratory triages (96%), avoidance of crowds (96%). As for the rest of the recommendations, there was little agreement between the authors. Conclusions.  There is no uniformity of recommendations in this literature review. It is necessary to carry out a greater number of systematic reviews to create validated guidelines, through the methodology of Grading of Recommendations Assessment for preventive clinical practices in order to standardize these recommendations in all ophthalmology services.
